Dealing with bigger models

Status: New Idea
by Valued Contributor mgaafar on ‎07-26-2014 11:46 AM

Hi, So I noticed that as the model gets bigger in size due to big number of elements the model tends to be slower and slower to manage. at this point, and editing in the model will consume lots of time.

I think this happens because RSA saves all the information in one file and as the user edit the model, RSA saves the information in its location in the file and by the time RSA finds the location in the file and edit the code and regenerate that takes a significant time in some cases..

any file has total number of node more than 20,000 things start to get slower and slower.

I hope the programmers can find an algorithm or a way to speed up working with large files. (may be by splitting iinput file into different files or something similar).

Hi everyone,<br><br>It could be absolutely powerful if will be added the option to optimize each bar in the code check, as happened in SAP, in this way the user can define a family of cross section and each bar can be searched in this family. After the first optimization run it is possible to group some member into a "SAME-CROSS-SECTION" family and go on with the optimization and the checking of all the bars.<br><br>Greerings

fix section builder

Status: New Idea
by Valued Mentor on ‎01-13-2014 07:23 PM

The section builder tool is very good, although there are some problems. 


  1. the naming convention is USELESS.  only being able to give a 4 letter description is very limiting.
  2. not being able to save a new profile as a concrete beam is limiting.  the section definition only allows reduction of moment of inertia for steel sections, and any user defined section can only be used as a "steel" section.

Adding beam restraints/internal bracings

Status: New Idea
by enda.farrell1 on ‎05-27-2014 06:02 PM



It would be very beneficial to make the input and display of beam restraints more user friendly as the current method is not straight forward. This is the only reason I avoid using Robot for Portal Frame design.


I have attached a pdf screenshot from another program which is the easiest I have come across to input beam restraints. It also shows an overall structure view of the restraints so it is easy to see if there is a restraint out of place. I find it can be easy to get member restraints backwards or upside down without this view. Just a tick box in display to show restraints would be fine.


Setting restraint points is much quicker because its done from one dialog box for all restraints. This may be something which could be developed in the short term with excel using macros and linked to Robot by creating a new Member Type? 


Please see http://forums.autodesk.com/t5/Robot-Structural-Analysis/Adding-beam-restraints-internal-bracings/m-p... for initial discussion on the above.

Parametric sections C, U, Sigma

Status: New Idea
by Valued Contributor aruser on ‎05-08-2014 03:05 AM

Add to the parametric section tab more sections such us C,U, Sigma. Definig general dimensions, thickness AND BEND RADIUS.


Obviously calculating them as thin walled sections when thinner than 3mm.


Please, this is ESSENTIAL

Legend Colour

Status: New Idea
by Valued Mentor on ‎01-09-2014 01:52 AM

Allows to change colour in the legend when using this for example for section type etc .... sometimes when using a lot of different types, it pretty hard to see the difference even if painting is a hobby!

Steel connections

Splice connection between steel members. Also it would be very
useful the designer to have the information of the weight of the steel

change moment of inertia for any section

similar to how you can change moment of inertia for a concrete beam, extend this functinality to ANY section type.

Node selection

Status: New Idea
by Distinguished Contributor Tuctas ‎02-16-2013 10:51 AM - edited ‎02-16-2013 10:53 AM

  When we select a node by indicating its number, it is marked with a green color spot in the structure but if the structure is a little more than simlpe it's difficult for the user to see where it is... It should be marked by a different (more clear) way, for instance the node could be enclosed in a small circle in order to be visible.

Push over

Status: New Idea
by Distinguished Contributor Tuctas on ‎12-29-2012 10:35 AM

  A general update in push over analysis should take place.

  There are several issues that must be resolved in order this type of analysis to be completed in Robot. Some of these are already posted, for instance the following links:






..and many others like the ability to set a starting case (usually containing dead and live loads) before the push over analysis  e.t.c (I think that some of them are already posted as SR in Subscription Center).

Currently you can add bars to a group which is very useful to select those bars after. But if you want to change some properties such us the material, the section, the release or whatever, you have to do it one by one. I mean, select the bars, then change the section, after change the material, after change the relase...


In my opinion, would be very useful the posibility of make a kind of "MASTER GROUP" which not only save the selection of the bars but also all kind of properties so, changing the property in the group you change it authomatically for all the bars belonging to that group.

That would be much faster to change and review.


Likewise for nodes.

It will be very powerfull if you can add an option in the panels or claddings definition that allow you to create a node-dependent panel or cladding.


In this way if you need to modify the structure geometry by node coordinate, you can transfer this modification automatically in the panels or in the claddings, avoiding geometry imprecision in model definition. 


It will be very powerfull in large models or in complex geometry model.

geometry and interoperability

Status: New Idea

Stories Tables :

1.reduced forces should be given either,  by each storie, and cumulative from stories above (same as displacement). these effort to be given at the bottom of the storie.


Loads :

1.Copying storie from a level to another shoud copy all element belonging to it,  especially  loads  affected to its elements , regardless the way it was defined ( loads on contour , linear loads …)

2.indicating the value of load when draging  the mouse over.


Export to RC design :

1.Names assigned manually to elements in RSA should be retrieved when exported to correspondant RC design.

2.adding preference of soil definition and optimisation pattern to be applicated to set of Foundation at once
