I'm drawing a frame sructure on ASD (Autocad Structual Detailing). I linked the fame to Robot Structual Analysis. However, connection of the frame on ASD didn't convert to RSA (see attached). Please show me how resolve it?
Unfortunately, thre is nothing to help with in such functionality.
Connections are migrated in backward model transfer, fron RSA to ASD.
It is just because the most common workflow was from calculation and code design model to drafting one.
Opposite workflow was not developed in such way.

One more thing. In RSA you can't add the second Stiffner (the one from the Beam's lower flange), so the Connection is not Exactly the same.
Plus what Jakub said....
I have a different opinion. When Robot calculates the connection accordin to EC3, the Shear Panel relations take in consideration the distance between stiffners.
So if you have a stiffner in the middle of the Column Web that connects the flanges, the Aria to be taken in consideration is half.
Am I missing something?
P.S.: Jakub vs Iacob
I know a formula that says:
t.w= is the thickness of the column web (and additional plates)
d.p= the distance between the stiffners
h.ws= the height of the columns web.
Also you can check a connection in Robot that doesn't satisfies the code : "Web panel - shear". Add an inclined stiffner (this option exists) and usually it solves the problem.
I've atached a picture from EC3 part 8.
I have other question. When I calculate deformation of beam HP14x117 with same boundary conditions (The lenght of beam is 4m. On head of beam is fixed and other is pinned. Pressure is 10kN/m)on Inventor (without stiffeners and with stiffeners) and RSA after that they have different results as follows:
1. On Inventor without stiffeners: max deformation is 0.1452mm
2. On Inventor with stiffeners: Max deformation is 0.2078mm (I wonder why has the result?)
3. On RSA without stiffeners: Max deformation is 0.136mm
Please show me why have the different results?

One more question:
I have frame on ASD (see picture and attached file)
When I link the file to RSA, have some issue as follows:
1. Purlins convert to beam and rigid link. Is it suitable? How can do it? which situation can apply rigid link like that?
2. Connection of bracing to colunm is disappeared
3. When I calculate the frame, RSA has note hereafter:
Please tell me how resolve them? Thank all you so much.
