I need to perform a finite element analysis on a structural frame. it is 80ft x 40ft structure, not your typical mechanical engineering part. I normally use CIVIL 3D, but we already own an ACAD package that includes the ACAD mechanical package. I would have to load it AND learn to use it, a costly (time = money) venture. I want to make sure that I can actually get there from here using mechanical ACAD. Please help.
