I don't get excited about the FREE Cad or CAM software packages very often. So for me to even post something like this is a stretch for me.
This looks exciting.
Autodesk has been in my arena of usage for many many years. I cut my teeth on AutoCAD R9. I bought a student version of R10. I took AutoCAD in college as part of my degree program. I used Mechanical Desktop, which was my first go at 3D modeling. I was a draftsman using AutoCAD for several years. I even used AutoCAM, for several years.
So - Fusion has been out for a couple of years but I never looked at it. Today I did look at it, and it looks good at first glance. It appears to be full 3D, and not just BAS relief.
Anyway - it is certainly worth looking at.
