I am building Gh codes for 3D trusses nowadays, and I would like to analyse them also in Karamba.
My problem is that I can’t figure out how to give different cross sections to different elements (flanges/all other beams).
Whatever I try, it says ‘Rigid body modes’ during analysis. I assume it has to do something with line intersection points (the model seems to be collapsing) but I just can’t find a way to handle this properly.
- If i intersect all the lines and put them in ‘Assemble Model’ , it is working fine.
- If I separate lines to different branches, intersect them and put the results in separate ‘LineToBeam’ components, then it crashes.
Any suggestions how to overcome this issue?
(The columns, braces are derived from division points of the flanges so the end points should be connected perfectly)
