I’m in Inventor training this week. Autodesk Inventor, to be exact, Autdesk’s second attempt to compete with real 3d products. Their first attempt, Mechanical Desktop, was a failure of biblical proportions, and frankly, this should be too. I am stuck with this, our company has chosen to go down this dead end, and I have to try to make it work. Ayone out there who needs a decent 3d design tool, look ANYWHERE but Autodesk. Save yourself!
