Hi all
During the tests in Inventor, it was possible to export the structure to the .rtd format in order to import it into the Autodesk Structural Robot calculation software.
Do you know if it's possible to do the same with SW? Should we go through another format?
We tested the . DWG, step, ifc, sat and igs but without real success....
Thank you!

Hello
In my opinion the only solution would be to go through a neutral format to import into Invetor to export in RTD.
Since the two software programs are part of the same company, they try to keep as much control over the whole process as possible.
I am indeed afraid that .PL is right.
maybe you can test a scheme by exporting in DWG, then open it with Autocad and see if it's then possible to do it in RTD
(if you have everything in 3D, maybe it works with autocad 3D? I admit I don't know much about this software :s)
Does it still smell like a bit of a messed up footbridge;)
Yes, the big problem is that we want to get the 3D sketch (the skeleton) of the structure in order to put it in Robot, but:
It seems to me (to be confirmed) that it is impossible to convert a SW sketch to a dwg or another format because the export will only take the 3D bodies.
So I'm stuck on this export point ...
@coin37coin, I can actually do this "shenanigans" by going through Inventor which converted to RTD format but I can't find this bridge between my 3D SW sketch and the DWG
But it's strange that in SAT or AICI, it doesn't work, see this video:
https://www.youtube.com/watch?v=Eb54_D4QSvo
Otherwise, the only roundabout way I see, but it can take a little time, is to export the DWG of the front, side and top views. Then in DraftSight for example, reconstruct the 3D DWG "by hand"... to export it afterwards...
I just watched your video and indeed it works on volume but I didn't manage to export a 3D sketch. I think the software converts surfaces into data but since a 3D sketch is wireframe, it doesn't find a surface.
Yes indeed for a 3D sketch remains the other solution I proposed in my last message, but it's tedious.
Hello
Late answer but hey, I just did the test at a customer and in IGES by checking the export options of SolidWorks, the export of 3d sketches and or 3d curves, it works.

Hello
I dust off the subject
A question about the Autodesk Inventor Structural Analysis in Buildings.
In my case when I open robot (2022 version) I can't find the complement. As its name suggests it's a complement, but when I go to the store I can't find this complement!!
Robot I begin, I have only modeled a framework once
Record broken! 
I wanted this record, I wanted it 
I'm proud of myself...
Not even, a record missed a year too early!
You get on the small step of the podium on the other hand!
See the attached top:
Top_Deterrages_20261019_164625.pdf (93.7 KB)
Some have free time!!
If not, what does the " DU " column correspond to?
Is it VBA?
It's the AI that made me the code in 10 minutes (1 or 2 corrections and functional!)
And for something of importance like that, you have to spend the time you need @Le_Bidule ! 
PowerShell script below.
I didn't know anything about it and I admit it's rather powerful and I've done other internal scripts in my company since then (still with AI since I don't know the language!
For those who are interested in putting it in a file to save in .ps1 (with the notepad), then have it executed.

Edit:
@Le_Bidule column naming error indeed.
Du is the number of years between the last message and the digging.
Subject replaces Year as the column title and the rest is shifted a notch to the right! I'm going to yell at the AI right now, not fucked up to do something right!
interesting all this (although...)

And as a bonus, the comment of the " Cat " on the script itself:
A small anomaly spotted by the way: your header row contains 5 columns (Années, Du, Au, Messages, Sujet) but each row of data produces 6 (one too many for the row). Add <th>Rang</th> to the top of the header row so that the 6 columns all have a title — otherwise the rows column has no title in the report.
The cat has mistakenly missing the label for the link column:
Fixed the table part that was wrong:
<table>
<tr>
<th>Sujet</th>
<th>Années</th>
<th>Du</th>
<th>Au</th>
<th>Messages</th>
<th>Lien</th>
</tr>
And for @FRED78 I don't site the name just the link to the subject, it shouldn't become a habit or a search for the feat!
Top fixed (the column names and rankings remain unchanged!)
No, this is not the feat we are looking for, this subject is interesting in my case. We work on SW and inventor, among others, and in calculation on ROBOT. In view of the modeling on ROBOT, using CAD software is a good solution.
What is the purpose of these statistics
None!
It was just on another unearthed subject that I had this absurd idea but which makes me laugh!
Good luck with your subject on which you will note, I have nothing concrete to offer you!
