Moving Beyond TinkerCad (from part design to system design)

So far I’ve loved TinkerCad to design functional 3D parts. I tried a lot of software (Sketchup, Fusion 360) and just settled into using TinkerCad not only because it was easy, but it wasn’t limiting me in any way.I’m at the point now where I’ve designed a “system” (for lack of a better word) of ~50 3D printed parts that I’ve designed in TinkerCad.I find myself constantly having to print new parts because something doesn’t align right, or my math was off by 1-2mm.I would really like something that I can load all my “parts” into and assemble my “system” in 3D. This way I could check my alignment and verify everything looks good before I start printing. It would decrease my total design time by a very large multiple.I still like the idea that I can design just 1 part in something like TinkerCad but I really need something where I can basically test assembly of my system before wasting time/energy/money into a failed (design wise) print.Can anyone suggest a product that allow me to do this? (I don’t want to consider sketchup, I find it too difficult to design functional parts) http://ift.tt/2dtGb1V

First time i felt i didn’t get enough Acetone, so i tried again. Evidently that was a mistake although I’m not sure why doing it a second time results in something so ugly. Might work great as an effect for wart covered halloween mask parts.
