Educational copy 13 month licence for FREE
One of my trainee technicians has informed me of something very interesting.
His lecturer has told the student on his course to login in and download the Autodesk software they need so that they can learn how to use it and produce material for their coursework for FREE
Here is the link to the Student Engineering & Design Community :-
http://students3.autodesk.com/?nd=public_signup_v2
I had been looking into the purchase of an educational licence so that I could continue learning the package at home in the evenings. (The company I’m currently working for has not purchased REVIT yet, they are still looking into it).
If you have a school-issued email address you can get started immediately on the new member registration page.
The Autodesk resellers I contacted did no know about this and they had directed me to an academia software site where they are currently selling the same Student / Teacher 13 month licence at £59.99 Buy Online
As with most Autodesk educational software there is a plot stamp embedded within the files produced that states that the drawing has been produced by an educational version.
So make sure that your students know that they are to keep their learning copy at home and the office copy (should you have one) well away from each other i.e. don’t use any files from or produced by the educational version on real work.

Long Time No Blog ..........
I’m sorry for the absence of regular postings to this blog site…
In May this year I moved to a new company that currently does not have Revit (Ok I’m working on that one.) There is the recession on (opps can’t call it that call it a “credit crunch” sounds less threatening) the fear of the workload dropping and the whispers of companies laying off engineers, graduates and draughtsmen.
I can understand that belts in the industry are going to be tightened until we see what the future brings, and there is a lot of financial difference between using seats of AutoCAD and AutoCAD LT and Revit with the cost in training and implementation etc etc.
One of our Major clients insists that we use a particular 3D drafting package for there work so, we also have seats of that for their work as well as seats of AutoCAD, LT Civils etc.
I still attended the London UK Users Group run by Excitech (despite not getting paid for the day, booking it as unpaid leave) because I believe the future is Revit shaped.
I’m biting the bullet and installing the Trial version of Revit Structure 2009 to continue up the Revit Learning Curve, but there is only so much one can do without the facility of being able to save and then reload your tutorial work and continue.
During the last couple of weeks I started on a project with an Architect who bought Revit Architecture, went on a three day course but due to pressure of work is still pumping out drawings using AutoCAD and has not made the transition. It’s no good going on any kind of software training if you don’t use the package before and more importantly straight after the training.
He discussed the possibility of re taking the course (as it’s been well over a year since the last one) and trying to make the move again, the Partners where I work are obviously interested in Revit and lets face it the cost of Revit Structure Suite which comes with AutoCAD is not a lot more than just plain Full AutoCAD if you need to upgrade of buy another copy of Full AutoCAD that is.
That’s the problem justifying the need for Revit or a Full AutoCAD then getting Revit off the back of the purchase. Slowly slowly catche Monkey as my old dear departed Dad would say.
The Architects building would be a challenge in Revit purely because it is curved and you could not use gridlines. I’ve not seen a lot of non –rectangular or rectilinear building detailed in Revit. This building is curved on plan and terraced, looking as if it should be in Spain or some other holiday spot not in the centre of London.
So if there are any Revit heads out there that have curved masonry building on plan I would love to see them.

Impression Update
A big thank you to all those people that sent me example files to forward to Autodesk
These were sent to assist build a case for Revit Structure , Suite and MEP users on subscription to get Impression
Lisa Crounse Product Marketing Manager for Impression emailed me today to inform me that "The team has decided that Impression will be available to Revit Structure customers (both the stand-alone and suite)" She later informed me via email that "Revit MEP is also on board"
She also gave me permission to make this public knowledge
Thanks Lisa and all those at Autodesk that helped make it happen.

Will Revit Structural Suite Users get Impression ?
Autodesk has announced that Impression will be offered as a subscription benefit for customers with AutoCAD, AutoCAD Architecture, AutoCAD Civil 3D, AutoCAD Map 3D, AutoCAD MEP and AutoCAD Revit Architecture Suite in March.
I have not seen any mention of Revit Structure Suite, which comes with AutoCAD so do we or don't we get Impression if we have subscription?
My reseller could not tell me, as they did not know
As a result of sending a support request to Autodesk, I have been contacted by Senior Management at Autodesk who initially asked me to build a “use case” for Structural Engineers owning Revit Structure under subscription to get Impression as part of the subscription.
In my reply I explained that Quote:
“I have not seen any mention of Revit Structure Suite, which comes withAutoCAD so do we or don't we get Impression if we have subscription?
AutoCAD is part of Structure Suite so we should but it's not mentionedin the resellers newsletter sent by email
Reading your (Autodesks) own literature
We would use it to "impress our colleagues and clients with compelling presentation-ready graphics created directly from DWG and DWF Files".
Structural Engineers in the UK do a lot of smaller schemes without the assistance of an Architect, as our drawings are sufficiently detailed for there not to be the need for an Architect. We (Structural Engineers) also undertake Civil Engineering. In the UK we take an Honours Degree in Civil Engineering and usually take the final year options of Advanced Structural design.
A picture is worth a 1000 words and the better the picture the better the understanding.
This package would be useful for civil engineering schemes which include landscaping.
I hope this helps you understand the use cases, Bottom line has to be if you are making this available to people that own AutoCAD then Revit Structural Suite owners should get it.... I just wanted it confirmed and if not lobby for it to be made available to us”
There have been further exchanges of emails and I have been requested to send some example drawings to assist in building the case.
Unfortunately I recently had my backup hard disk die on me so I am having to scour through piles of CD’s to find some good examples.
If Structural Engineers could send me some example dwg or pdf files to my work email at alan.wooldridge@byl.co.uk then I can collate them and send them back to Autodesk I would greatly appreciate it.
And then we Revit Structure Users may end up with a very useful additional tool.

Revit Structure 2008 Shortcuts Quick Reference
There are many predefined keyboard shortcuts for Revit Structure commands.
This document lists the shortcuts by Menu Item - I have printed out two copies, placed them back to back, then encapsulated them in plastic using the a laminating machine to keep nearby as a reference card.
I have also found that you can also configure your own keyboard shortcut key combinations that appear in the Revit Structure interface next to their corresponding menu item.
You can create multiple shortcuts for one menu command. In the menu, the shortcut that displays in the menu is the first shortcut listed in the KeyboardShortcuts.txt file. A job for when I'm more proficient with the package I think!

All Robobat Extensions FREE on Subscription
On the 15th Jan 20008 - Autodesk, Inc. announced that it has completed the acquisition of Robobat for approximately $42.5 million.
Today 2nd February 2008 there was an announcement on AUGI by Wai Chu Autodesk, Inc Technical Product Manager for Revit Structure that all extensions for Revit Structure formerly developed by Robobat, both fee and free, are now available through the Autodesk Subscription Program.
We are told that Revit Structure Subscription customers can login to the Subscription Center and download the Revit Extensions at no additional cost..
But they seem to be having problems again because at the moment I can’t see anything on the Subscription pages.
It took a couple of days for them to get their act together with the Work Sharing Monitor and Batch Print for Revit for UK subscribers.
Revit® Extensions are a series of easy to use applications that extend the capabilities of Revit Structure 2008 in various key areas, including structural analysis and reinforced concrete drafting.
To find out more about this acquisition of Robobat read the press release.Visit the Autodesk’s Subscription page under Services and Support to find out more about this service and becoming a member.

Revit Libraries Reference Guides
Earlier this month I posted information about Revit Libraries available from Autodesk on my Blog.
Well I’ve been downloading, unzipping and comparing these files with what gets installed of the DVD in the box when you buy or get the 30 day trial disk and guess what?
The information available on the web site at http://revit.autodesk.com/library/html/index.html is 12 days older that that on the DVD and there a handful or extra folders and families available from the dvd!
I’ve gone to the trouble or recreating the files structures and in some cases listing the families (errors in spelling and all) and I’ve sent them onto Autodesk so they can correct them for Revit 2009
I’ve turned these documents into Adobe Reference guide which I’m posting on my web site download page http://www.cadalot.co.uk/revit/download.htm and the AUGI forum at http://forums.augi.com/showthread.php?p=805643#post805643

New Revit Tools on Subscription Site (Finally!)
Earlier this week a number of Blogs reported two new tools for Revit 2008 having appeared on the Revit subscription web site; these are the Work Sharing Monitor and Batch Print for Revit.
For some reason not everyone got to see the links on their subscription page – Guys in the United States were reporting seeing a “globe tool” – I only got to see the TrussWizard and Subscription Structural Library until today - four days after notice was given that these tools were available?
So what (if anything) am I or you come to that, missing?
Answers please on a postcard - Scratch that, just post a reply here if you have any info on the Globe Tool and anything else I should be able to see but can't! or please email me

More families at AUGI forums
The AUGU discussion Forums are another source of Families This week on the Revit Structure - Families
Topics about creating families specifically for Revit Structure.
A Revit Structure user called djn (not a lot of other information about him or her other than that) posted their first attempt at created a type catalog for concrete beams and columns. See thread http://forums.augi.com/showthread.php?t=73983
The types start with 12 x 12 and worked up to 48 x 48 by 2s, although this doesn't account for all beams or columns used, djn thinks it will account for most of them.
The rfa, txt and the Excel source files are included for
Concrete-Rectangular-Columns
Concrete-Round-Column
Concrete-Rectangular-Beam
I’ve download the files and had a play. I've created a metric version of the Excel spreadsheets and then the txt file (saving as csv then re-naming as djn suggested). As the originals I've starting at 300 going up to 1200
The metric Excel source files and and txt files have been posted back to the thread.
It's worth keeping an eye on the AUGI forums

UK Revit System Family Files - Wall Libraries
The reason I’m telling you UK Revit newbies about UK Wall families is that if you don’t have a Dan type person handy, you will be stuck with the Basic Wall types that get provided in the templates and not know about the UK walls available for download and will have to create your own.
What is a Dan type person? Dan is a fellow Revithead and friend who is a Building Surveyor that has been using Revit Architecture for a couple of years. “ since when it was called Revit Building 3” so he tells me.
I see Dan once in a blue moon, and he has just found out that I have bought and I’m learning to fly Revit Structure. So recently when he was down from Birmingham doing a job in London and staying over, he came over in the evening for a meal, but also came with his laptop with Revit Architecture so we could play with Revit after.
The good lady wife didn’t mind as she had her Emmerdale, EastEnders, back for Coronation Street etc.etc. then finally she went to bed on her own, whilst Dan and I were still Reviting the night away…… (sad isn’t it)
We got around to discussing making UK specific families and me wanting to create my template with useful stuff already loaded in like UK walls etc. and Dan (bless his cotton socks), produced a family file called GRBENU_Walls.rvt that he had downloaded from http://revit.autodesk.com/library/html/index.html
When you get to the web page select
Revit Architecture 2008 Library \ UK Library \ System Family files
And you should see
Lot’s of lovely stuff to harvest and get lost in…..
I assume that the name GBR is Great Britain but I’m not quite sure what the ENU means possible something to do with EuropeaN Union.
Now it has to be said, when it comes to Revit Family files there are so many available from so many different locations on the Autodesk web site and it is quite confusing just what is in what file.
There are many Templates and Libraries available for download at
http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=9262782
The ones in Metric and for the UK appear to be under Core-Structural Content (Non-Translated, English Only)
StructuralLib.cab (cab - 135 Mb)
StructuralTempl.cab (cab – 8.65 Mb)
StructuralMetLib.cab (cab - 127 Mb)
StructuralIntMetTempl.cab (cab – 9.94 Mb)
StructuralMetTempl.cab (cab – 6.91 Mb)
But what’s in them? And what are the file names trying to tell us? Reasonable guess that Lib is a Library and Templ is a Template but what’s the difference between
StructuralIntMetTempl.cab (cab – 9.94 Mb)
StructuralMetTempl.cab (cab – 6.91 Mb)
Apart from the title and size?
And how do these differ from what comes with Revit when you install it from the DVD?
Looking down the page at Locale/Region Specific Structural Content (UK Only listed below) we find
UK.cab (cab – 309 Mb)
UKRSTLibrary.cab (cab – 16.2 Mb)
UKRSTTempl.cab (cab – 6.99 Mb)
Again UK is United Kingdom RST got to be Revit STructure, this time Library is in full and Templ is obviously Templ-ates, but as before the question is how do these differ from what comes with Revit when you install it from the DVD? And what about the content from the
http://revit.autodesk.com/library/html/index.html page where we found the UK Walls – are these duplicated in UKRSTLibrary.cab?
There are no version numbers, text readme files or anything else with these Libraries and templates that will enable you to keep track on what you are downloading what the latest version is etc.
As I bought Subscription I recently downloaded the Metric Subscription Structural Library which appears to be called MetricContent.zip no matter which version it is. So when I downloaded it and unzipped it went into a folder called 200801090. Now that raises the question “so what happened to the last one I downloaded which was also called MetricContent.zip but unzipped into a folder called 220070608?”
Autodesk don’t seem to keep archive material in the Subscription download area?
Again there is no readme file to tell you anything about the content of each version.
Do the subscription libraries ultimately make it to the next version? or some other file somewhere? Who knows? How as an end user, do I manage this?
Getting back to the GRBENU_ Walls.rvt file. Thank to the Autodesk for producing these and saving me and many other Revit UK user heaps of time creating them, here is some constructive feedback for improvements to the GRBENU_ Walls.rvt file for the future.
The image in the left is a screen dump of the Basic Walls Types provided in the GRBENU_ Walls.rvt file.
OK looking just at the names we should be able to work out the makeup and purpose of each file. BUT if a text file were provided with that information already
First thing that jumps out is we have dense and Dence < is this a typo or an American way of using English?
OK looking down the list
Cav obviously means Cav-ity
45i means 45mm
i-nsulation
P means P-laster
Not sure about what dense does in revit and I’m assuming the Lwt means Light WeighT
22r means 22 r-ender
Third one down Cav 22r 100 50a 30i 100 P – Lwt I have no idea what the `a’ after the 50 could mean – possibly a-ir gap But if it is a for a-ir gap then then Cav 102 50 30i 100 P Lwt should have an `a` after the 50 Also we have dash – Lwt and just Lwt without the dash being used.
Picky I know but If it’s a naming system then it’s got to be consistent (it’s the Structural Engineer in me coming out to play)
Now having come up with a naming convention we get Cav R102 75i 100 P – Band + Render, So what happed to specifying the thickness and render as in Cav 22r 100 75i 100 P –Lwt and why use a capital `R` and not the lower case `r`, there is also nothing to say if it’s dense or Light Weight in the name?
Ext – Ext-ernal
Int- Int-ernal
Then there is the Basic Wall: Int Pa 100 75 100 aP PartyWall What’s the `a` between the Plaster and the Blockwork? Could be `a` for air gap perhaps plasterboard on dabs?
Partn – Part –itio- n
Partn 95mm 1/2 Hr
Partn 120mm 1 Hr Partn 130mm 2 Hr
OK give up? What are these? We have Blockwork and Studwork listed, but all we know about these are their fire rating.
We then get 100, 140, 190 and 215 partition walls with Plaster either one side or both sides but not without plaster on both. I’ve done a lot of school new builds and extensions where the keep the cost down facing blocks have been used so there is no need to plaster saving time and money on the scheme. So what about adding them to this Library?
Site 215 Brick w Footing `w` means w-ith
Then we get concrete walls with plaster on one side, so where are the plastered both and without?
My observations and assumptions listed above have been made before I’ve interrogated the properties of the walls in question, so it’s off I now go to find out the answers to the questions and verify the assumptions I have made above.
Again I stress that a simple readme.txt file providing basic information would save me and many others having to investigate our assumptions. I was told never to assume as it makes an ASS out of U and ME.
I will return at with the results of my investigations in a later posting.
What is a Dan type person? Dan is a fellow Revithead and friend who is a Building Surveyor that has been using Revit Architecture for a couple of years. “ since when it was called Revit Building 3” so he tells me.
I see Dan once in a blue moon, and he has just found out that I have bought and I’m learning to fly Revit Structure.

The good lady wife didn’t mind as she had her Emmerdale, EastEnders, back for Coronation Street etc.etc. then finally she went to bed on her own, whilst Dan and I were still Reviting the night away…… (sad isn’t it)
We got around to discussing making UK specific families and me wanting to create my template with useful stuff already loaded in like UK walls etc. and Dan (bless his cotton socks), produced a family file called GRBENU_Walls.rvt that he had downloaded from http://revit.autodesk.com/library/html/index.html
When you get to the web page select
Revit Architecture 2008 Library \ UK Library \ System Family files
And you should see
Lot’s of lovely stuff to harvest and get lost in…..
I assume that the name GBR is Great Britain but I’m not quite sure what the ENU means possible something to do with EuropeaN Union.
Now it has to be said, when it comes to Revit Family files there are so many available from so many different locations on the Autodesk web site and it is quite confusing just what is in what file.
There are many Templates and Libraries available for download at
http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=9262782
The ones in Metric and for the UK appear to be under Core-Structural Content (Non-Translated, English Only)
StructuralLib.cab (cab - 135 Mb)
StructuralTempl.cab (cab – 8.65 Mb)
StructuralMetLib.cab (cab - 127 Mb)
StructuralIntMetTempl.cab (cab – 9.94 Mb)
StructuralMetTempl.cab (cab – 6.91 Mb)
But what’s in them? And what are the file names trying to tell us? Reasonable guess that Lib is a Library and Templ is a Template but what’s the difference between
StructuralIntMetTempl.cab (cab – 9.94 Mb)
StructuralMetTempl.cab (cab – 6.91 Mb)
Apart from the title and size?
And how do these differ from what comes with Revit when you install it from the DVD?
Looking down the page at Locale/Region Specific Structural Content (UK Only listed below) we find
UK.cab (cab – 309 Mb)
UKRSTLibrary.cab (cab – 16.2 Mb)
UKRSTTempl.cab (cab – 6.99 Mb)
Again UK is United Kingdom RST got to be Revit STructure, this time Library is in full and Templ is obviously Templ-ates, but as before the question is how do these differ from what comes with Revit when you install it from the DVD? And what about the content from the
http://revit.autodesk.com/library/html/index.html page where we found the UK Walls – are these duplicated in UKRSTLibrary.cab?
There are no version numbers, text readme files or anything else with these Libraries and templates that will enable you to keep track on what you are downloading what the latest version is etc.
As I bought Subscription I recently downloaded the Metric Subscription Structural Library which appears to be called MetricContent.zip no matter which version it is. So when I downloaded it and unzipped it went into a folder called 200801090. Now that raises the question “so what happened to the last one I downloaded which was also called MetricContent.zip but unzipped into a folder called 220070608?”
Autodesk don’t seem to keep archive material in the Subscription download area?
Again there is no readme file to tell you anything about the content of each version.
Do the subscription libraries ultimately make it to the next version? or some other file somewhere? Who knows? How as an end user, do I manage this?
Getting back to the GRBENU_ Walls.rvt file. Thank to the Autodesk for producing these and saving me and many other Revit UK user heaps of time creating them, here is some constructive feedback for improvements to the GRBENU_ Walls.rvt file for the future.
The image in the left is a screen dump of the Basic Walls Types provided in the GRBENU_ Walls.rvt file.
OK looking just at the names we should be able to work out the makeup and purpose of each file. BUT if a text file were provided with that information already
First thing that jumps out is we have dense and Dence < is this a typo or an American way of using English?
OK looking down the list
Cav obviously means Cav-ity
45i means 45mm
i-nsulation
P means P-laster
Not sure about what dense does in revit and I’m assuming the Lwt means Light WeighT
22r means 22 r-ender
Third one down Cav 22r 100 50a 30i 100 P – Lwt I have no idea what the `a’ after the 50 could mean – possibly a-ir gap But if it is a for a-ir gap then then Cav 102 50 30i 100 P Lwt should have an `a` after the 50 Also we have dash – Lwt and just Lwt without the dash being used.
Picky I know but If it’s a naming system then it’s got to be consistent (it’s the Structural Engineer in me coming out to play)
Now having come up with a naming convention we get Cav R102 75i 100 P – Band + Render, So what happed to specifying the thickness and render as in Cav 22r 100 75i 100 P –Lwt and why use a capital `R` and not the lower case `r`, there is also nothing to say if it’s dense or Light Weight in the name?
Ext – Ext-ernal
Int- Int-ernal
Then there is the Basic Wall: Int Pa 100 75 100 aP PartyWall What’s the `a` between the Plaster and the Blockwork? Could be `a` for air gap perhaps plasterboard on dabs?
Partn – Part –itio- n
Partn 95mm 1/2 Hr
Partn 120mm 1 Hr Partn 130mm 2 Hr
OK give up? What are these? We have Blockwork and Studwork listed, but all we know about these are their fire rating.
We then get 100, 140, 190 and 215 partition walls with Plaster either one side or both sides but not without plaster on both. I’ve done a lot of school new builds and extensions where the keep the cost down facing blocks have been used so there is no need to plaster saving time and money on the scheme. So what about adding them to this Library?
Site 215 Brick w Footing `w` means w-ith
Then we get concrete walls with plaster on one side, so where are the plastered both and without?
My observations and assumptions listed above have been made before I’ve interrogated the properties of the walls in question, so it’s off I now go to find out the answers to the questions and verify the assumptions I have made above.
Again I stress that a simple readme.txt file providing basic information would save me and many others having to investigate our assumptions. I was told never to assume as it makes an ASS out of U and ME.
I will return at with the results of my investigations in a later posting.

Revit Updates
Autodesk have posted a new build (20080101_2345) of Revit Architecture 2008, Revit Structure 2008, and Revit MEP 2008. It is still considered Web Update #3 because replacing the existing file was the fastest method of delivering it to the public.
Therefore, the executable file names are the same as the previous build (20071102_2345).
Here are the links to the updated downloads...
RAC: www.autodesk.com/revitarchitecture-download
RST: www.autodesk.com/revitstructure-downloads
RME: www.autodesk.com/revitmep-download

UK Revit Register
The UK Revit Register has been created on the cadalot web site to enable companies using Autodesk Revit Architecture, Structure and MEP to find other companies also using Revit based products in their region so that they can collaborate with them on schemes using a common program.
This should also hopefully promote some regional banding of individuals that may want to meet down the local public house or visit one another offices when they found out that they are not the only Revit user in the Village.
You never know, if enough people respond, perhaps regional User Groups may form around the UK?
There is an email hyperlink on the UK Revit Register web page to submit your details, don’t be shy register today.

Errors with Saving out Groups in the New Year
Messages on the AUGI Revit Architect and Revit Structure forums report an error that since the switch over to the year 2008, you can no longer save out your groups.
Here is the posted Revit Support Team response:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I apologize this issue is occurring as I know it must be frustrating. A workaround for now is to change the system clock to a month other than January 2008. The underlying issue for this case is being addressed by our development team on a future release. I am going to place this Support Request in a status called 'Pending Change Request.' It will not be closed and you will be notified when the enhancement has been implemented
Best Regards, Autodesk Support Team

Q: When is a Column not a Column? - Part 3
At the Excitech UK Revit Group London meeting in December 2007, I spoke to Chris George of CSC providers of Fastrak who were there do a presentation on “Fastrak and Revit Structure effective Integration”
He informed me Autodesk dictated to CSC that the prefix library be used i.e. UC152x152x23 and not 152x152x23UC. He also told me that Fastrak users will have problems if they mix family formats in a model. He later confirmed this in he presentation.
He also told us that for the most effective links use Fastrak Building Designer Version 7
With the latest patch (currently) = #4 and Revit Structure 2008 With the patch # 2 and NOT patch 3.
It would appear that Patch 3 introduced to fix issues with cellular beams, but introduces some unfortunate side effects – these have been reported to Autodesk by CSC.
In My Humble Opinion
Its about time Autodesk got it’s act together, this is not rocket science. Either sort the problem out with the UK Steel families or at least add a readme file in the folder to explain.
Ummm let’s see, if they had done that perhaps they would have found that there system was not really a system.
What these families need is an additional field called notation or name or something where the type is not used to name the section on the drawing. That can’t be to difficult to add can it?
When are the Corus Advance sections going to be added? They have been around since September 2006
Now will that be UKC152x152x23, or 152x152x23UKC, or 152x152UKC23 or a 152UKC23
One family with a method or changing the name displayed on the drawing or four families which will promote problems with analytical software?
Lets see that the next version of Revit Structure brings

Q: When is a Column not a Column? - Part 2
Enough of the background information on UK Steel sections back to Revit and columns as beam sections. Below is the example file I am working on to learn Revit. Structure. The columns on this are 152x152UC23 and guess what? the beam at the top is also a 152x152UC23.
Initially when adding the beam (which is a Universal Column section) I went to Metric Library\Structural\Columns\Steel, but the type selected would not load…..
Then the penny dropped…
Column families are created to be placed such that they are vertical and attach to slabs and foundations and grids with a single selection point where as;
Beams families are created to attach to columns and load bearing walls, and are specified by selecting two locations i.e. each end of the beam.
I was then presented with a choice? Ummmmm
Now what is the difference between?
UC-Universal Column.rfa and
UC-Universal Columns.rfa apart from the (s) after the word Column?
I then decided to investigate further ….
Looking at the two open family screen dumps they appear to be the same but……..
UC – Universal Column.rfa – starts at the largest serial size member and the UC designation behind the serial size and weight, where as;
As you only get to look at a small area of the type and property table I went to the folder loaded the two files into a text editor to print out and checked that they were exactly the same, and they are.
So the question was why are there two?
Cast your mind back to my explanation UK steel sections in When is a Column not a Column? -Part 1. Common methods of specifying steel in the UK are (using the same section as an example):
UC152x152x23, or 152x152x23UC, or 152x152UC23 and I have also seen 152UC23 (don’t forget that most, but not all, of the UK columns are square)
So a quick post on the AUGI forum and my suspicions were verified, because they type name is used on the drawing and people like to define the section in different ways and also some analytical software need the UC to be at the front and others need the UC to be at the rear we have two sets of the same family tables.
So you might be fooled into thinking that now you know the plural version of the family name, i.e the one with the (s) at the end, is the one with the section designation at the front this will apply to all the other sections.
BLAMP BLARRRR (A Big Family Favourites you got the answer wrong noise )
Don’t be silly no real logic has been used in developing any kind of file naming system lets take a look.
OK we have dealt with columns.
Beams, Yep there is a UB-Universal Beam.rfa and an UB-Universal Beams.rfa, quick check, Yep the same as the columns
UBP-Universal Bearing Pile.fra and a Piles.rfa – good
RSJ-Rolled Steel Joist.rfa and a Joists.rfa – good
But hang on what’s this why is there a
Rectangular and Square Hollow Sections.rfa
RHS-Rectangular Hollow Section.rfa
SHS-Square Hollow Section.rfa
Now why combine SHS and RHS in one format and separate them in another?
Then there is
PFCH- Parallel Flange Channels.rfa and
PFC-Parallel Flange Chanel.rfa
Ummm lets look
Looking at the type it’s a PFC with the designation at the front so what in blue blazes is the H for (H or Ho it’s the other way round to…. PFC-Parallel Flange Channel.rfa)
Then there are the Angles

Beams families are created to attach to columns and load bearing walls, and are specified by selecting two locations i.e. each end of the beam.
So …. back tracking up the directory structure and back down again to Metric Library\Structural\Faming\Steel

UC-Universal Column.rfa and

UC – Universal Column.rfa – starts at the largest serial size member and the UC designation behind the serial size and weight, where as;
UC – Universal Columns.rfa – Starts at the smallest serial size member and the UC designation is before the the serial size and weight.
A quick slide down the UC-Universal Column.rfs family type thus:
Yep, there they are 152x152x23UCA quick slide down the UC-Universal Column.rfs family type thus:

And I’ve always scheduled angles using 200x150L18 (size, shape, thickness) the same applies to channels.
Q: When is a Column not a Column? - Part 1
A: When it’s a Beam.
A quick explanation for the 37% of you, that visit this blog from the USA. In the UK we use steel sections called Universal Beams (UB) and Universal Columns (UC),
With Universal Beams the Height (h) or web depth of the section is larger than the breadth (b) or width of the flanges.
A quick explanation for the 37% of you, that visit this blog from the USA. In the UK we use steel sections called Universal Beams (UB) and Universal Columns (UC),
With Universal Beams the Height (h) or web depth of the section is larger than the breadth (b) or width of the flanges.
With Universal Columns the height (h) and breadth (b) are approximately the same.
Both UB’s and UC’s come in what is termed “serial sizes”
An example of serial size can be seen in the columns table extract shown above. There are three sections with serial size of 152x152 however to define the actual section specified, one uses the mass per metre, to more accurately define the section.
You will note that the actual depth of section and width of section are given and vary based on the increase in thickness of the Web and Flange and rolling tolerances etc..
One normal pre-computer design practice was to place the designation of UB or UC between the serial size and the weight to assist in avoiding any confusion between size and weight when specifying
i.e. 152x152UC23 = 152x152 serial size Universal Column 23 kg/m
203x133UB25 = 203x 133 serial size Universal Beam 25 kg/m
Another UK practice is to specify the section by placing the section designation after the serial size and weight i.e. 152x152x23UC. Yet another is to use the section designation in font of the serial size and weight i.e. UC152x152x23. This format lends itself to lookup tables for computer programs as it is easier to process information in a table if the section size is presented first in the information.
Now that being said there are occasions where a UK Engineer will use a column section horizontally as a beam, and a beam section vertically as a column, why? Because they can, and sometimes the nature of the situation lends itself to this, typical examples:
Beam sections are used as columns in portal frame structures because of the enhanced resistance to horizontal loads due to the section properties.
Column sections are used in domestic situations where the depth of the beam needs to be contained within a timber floor and the wide flange allows bearing of the timber
Universal Beams typically range from 127 x 76 x 13kg/m up to 1016 x 305 x 487kg/m. Universal Columns typically range from 152 x 152 x 23kg/m up to 356 x 406 x 1086kg/m.
Corus Construction & Industrial provides structural sections in accordance with the following specifications: BS4: part 1: 1993 and EN10056: 1999, ASTM A6/A6m, European narrow flange beams in accordance with Euronorm 89, European wide flange beams in accordance with Euronorm 53-62 and JIS.
From September 2006 the Corus Advance section range was developed to reflect current structural design practice and make it easier to specify Corus CE marked structural sections compliant with the EU Directive on Construction Products.
There are an additional 5 Column Sections and 24 Beam Sections in the Advance section range which are not given in BS 4-1:2005
Corus has trademarked new designations for use by the UK steel construction industry.
UB now becomes UKB
UC now becomes UKC
Asymmetric slimflor beams remain as ASB
Advance, UKA, UKB, UKBP, UKC, UKPFC and UKT are trademarks of Corus.
I’m suspicious that this was not only done to comply with the EU directive but also as a marketing ploy to specify the source of the steel specified by using the UKC and UKB etc designation which are Corus trademarks
