how can I define different beam sections for different lines?
I’m only able to define 1 type and if I try to define two, selecting one at a time, I get the error message when I run the analysis
BTW, if you set 3D output to true you gone see the different size of the sections. You do not even run an analysis for this. You could use the check analysis type for this. But you need an up to date FreeCAD and you need to add a new solver.
