Hi, I have a problem with static catia analysis. I have modified an object with additive manufacturing software and now I would like to import it into the catia for a structural verification. The problem is that the additive software gives me a file with an STL extension. I know that catia works with step files but I can't convert STL to STEP because the geometry is really complicated. Within the part the additive software has created very complicated lattice structures. How can I solve the problem?
