Well, let me say the feedback on this subject is quite interesting and well receieved, although I feel a little disillusioned. It appears that many are living in dreamland vs. reality. Like or not its about the almighty dollar in todays world and everything else is secondary. Although I agree that the lack of quality does not soley ly on the designers shoulders. If you look at the entire process needed to get an idea into the market, you will see that every step is budget conscience...and rightfully so. Lets face it companies are in business to make money, right? The problem is when business wants to make ludicrious money and make sacrifices in workmanship, employee benefits, etc., etc.. So whether your using the best or the fastest software doesn't make a hill of beans.
And in all honestly, theres software out there thats far better and faster than Autodesk Inventor but until businesses realize that there staff needs more time to make decisions and improve quality you might as well ustick with AutoCAD 2D. In fact that way you have an excuse when deadlines are missed.
