I tried A2+ before and it did not work well for me. I wrote this at the time: > I liked how easy it was to define constraints between the parts. Unfortunately I found that if I changed any of the parts in any way, then when I updated the part in the assembly, A2plus had lost track of which pieces of geometry were supposed to be constrained. This is very annoying and means you need to redefine the constraints for a part every time you change the part. I read somewhere that A2plus is best used when you have already committed to the design of the parts and you just want to assemble them together, but that is not really a useful workflow. If I've already committed to the design of the parts, I can just print them out and assemble them together in real life!
