Thanks for the comments, everyone. I am totally convinced that millions of man (or woman- hours) are wasted every year with all the senseless sketching that is mandated by almost all other MCAD programs. I still have to use AutoCAD in 2D at times and remember well the time I thought all the "contruction" line-drawing days were over. Little did I know that they would stick around well into the 2000s and beyond. In companies that have "gone with the flow" of sketch-type MCAD, I hear again and again the age-old saying "I'll just redline the drawing and let drafting take care of the rest." With IronCAD, the designers, engineers, AND draftspeople look forward to making an assembly or changing an existing design in 3D. As long as the non-users make the buying decisions, I see no major change in sight. Therefore, I believe the best strategy is to get the big shots to demo the programs. Yes, this may be a pipe dream, but boy, would companies save a small fortune if this were to happen!
