What to buy? We need a few of seats of a feature-based solid modeller here soon. Our main area of interest is sheet metal punching & folding, but some extrusions, spinnigs and springs. Most of the drawings at present are done in 2D (in rel14 and LT2000), but we are committed to moving into 3D solids. (most of the sheetmetal dwgs are exported as 2D dxfs or dwgs to the CAD software for our Salvagnini and Amada machines). We have the choice of Solidworks, ProE, Inventor or MDT. We have demos/presentations arranged from the resellers/vendors, but we need to ask the right questions to enable to make the right choice for the future. Has anyone here had to make a similar choice? Advice, pros/cons and links greatly appreciated. Many thanks, JB
