I'm an old guy that does a lot of woodworking so i use my printers to aid in this. I've been using AutoCad since early 80's (long time), and I typically use Fusion because it's an Autodesk product that I'm familiar with. Sketchup, SolidWorks are a couple other cad programs I use. I love doing architectural 3d models for clients, and then print them in smaller scaled models ... OH! And I love riding Mountain Bikes
