At work I use computer aided design (CAD) software to make 3D models of aerospace parts. At home I’d always been looking for good free CAD software, but never found what I was looking for. I recently revisited FreeCAD, and it has come far. It is still under active development, but it has a lot of the fundamental parametric features working that a hobbyist or mechanical engineer needs. Basically, you can make really good models in it, even though it’s not “done” yet.
Let’s See Some CAD Models
To try it out, I modeled some simple household items, like a cup, a spoon, and a fork. Then I made a jet engine exhaust frame, not based on any real engine. Take a look at the interactive results below. All models can be rotated and zoomed in with your mouse!
