for FEA i use AutoCAD inventor (Student License) because I thought it would be an easy transition from Normal AutoCAD, not the case tho, apparently its more like Solidworks where you work parametrically. Has Soildworks not got a FEA module I'm sure Ive seen them generated from solidworks.

Its worth down loading the trial versions, if you already have the 3d model then at least theres 30 days of free analysis :whistling:
