part-wb: create cylinder
arch-wb: select one or more surfaces on cylinder, press facebinder button
mesh it.

Re: CBFEM for steel connections

I must use CBFEM method or i can only use FEM method with shell element in freecad? and basically what is different between CBFEM and FEM?! We dont use the component method at work. It is only useful for simple 2D-connections, for 3D-joints it is too much work. IDEA-statica mixed the analytical com...

which ccx version did you use to get 0.365 mm?
No ccx. I just opened the beam-file from ickby, activated the FEM-wb and
displayed the results. No FEM-run. 0,44 mm are from recalculating.
How can I find out the ccx version? I see this:
