Zeb, that is super cool. Is Plasticity more like Blender, or more of a 3d CAD like Solid Works or Fusion 360 or so on?
Plasticity is marketed as CAD for artists. Similar to MOI/Rhino, but running on Parasolid kernel (NX, Solidworks) and a super smooth, modern UI. At $100 for the indie version, it is a screaming deal for a Parasolid port and you own the tool. He basically isn't making any money on the indie version, since a lot of that goes to porting Parasolid like other companies do.
Like Rhino, the biggest difference with standard CAD is there's no history timeline and no constraints on sketches. Angles and dimensions can all be entered, so you can be as accurate as you want. I create a folder named "Sketches" that I drag/drop items into and rebuild surfaces and solids out of it. Similar to Rhino except more intuitive for managing construction geometry. That might be a turn off for many here, but it's just a different way to model. No sketch constraints also brings a performance increase. I like to think of it as drafting on paper and using applied geometry.
If you have old STEP dumb solids from a CAD product you no longer have access to, you can re-dimension G1 fillets, faces, etc. Very similar to synchronous modeling in NX. If there's a face you want to move or a drilled hole you want to size, you click it and type in the value. A (G1 conic) fillet chain can be clicked and removed, then reapplied. It even has an experimental tool that auto removes fillets by size entered. etc. Some might stress about not having a rebuild history, but when there's no history to rebuild, things don't break as often.
I could go on, but maybe discussion for another thread for sure. Here's a doodle I made yesterday and even though I struggled quite a bit
trying different things in the recording, it took only 57 minutes to model. This is more a complement of the software.
Last word is that it won't do everything, but in my case it is a huge complement to Alibre for a NURBs modeling workflow. I can leave both on a machine in the attic for ten years, and if I have the itch it's easy to fire up and learn again.
