Hello,
I don't understand the difference between the .Iges/.Igs file and .step file in Mecway.
Using .Iges file I can't generate a solid mesh without create before a shell mesh.
Using .step file Mecway creates automatically a solid mesh (I tried with the "Cadworkflow" tutorial).
I create .iges/.igs file with Autocad but I can't create .step file. If Mecway can't create directly a solid mesh with .Iges file, is there a method to convert .iges file to .step file?
Thanks for tips,
Regards
Marco

On Salome platform sometimes there are issue importing igs because to build volume is necessary to change the tolerance on importing igs
I am trying to model and calculate in Mecway structural steel joint creating solid elements (with Autocad). Have you any advice of a software to create .step file?
Maybe drawing parametric objects for plates and bolts.
Thanks,
Marco

I don't use autocad for this pourpose but I think that isn't the best solution.
As Sergio wrote there are many CAD software. If you are student you can open an Autodesk account and you can use, without resctrictions, Inventor (or Fusion)

I am a structural engineer (civil) and I am trying to calculate structural nodes with FEA software to manage not-standard nodes (generally indications for standard nodes are in National Codes).
Software like Tekla are "closed software". There isn't the possibility to model nodes with complex geometry. Moreover are expensive softwares.
I will try with Freecad. I have seen the on-line documentation and the software can create parametric objects.
I would create a parametric node, export the geometry in FEA software and calculate it.
If some part of the node (plate thickness, bolts, welds) aren't verified, I can change easily the geometry and recalcute it.
At the moment my problem is to create the geometry, after this I think that I have to consider the constraints between objects and loads application (generally derived from a 3D beam model).

After that is possible to verify the bolt with the code (for example Eurocode 3 part 8).
If you are going to simulate with complete bolt as a body, obviously, don't consider the thred

By the way Andrea, how do you apply the temperature preload to a bolt? I have made some kind of analysis using that aproach in the past (with a solid bolt), but applying enough preload/temperature to reach 75% of bolt´s yield stress (after several tries), but there is some more technical procedure to reach a defined bolt preload?
