Overview of OpensCAD

OpenSCAD is a program used to make 3D models. But unlike most 3D
modeling programs, there are only 10 things you need to know in order
to be dangerous in OpenSCAD. Unlike most other 3D modeling programs
like Blender, Sketchup,AutoCAD, or Solidworks, it’s really easy to get
started in OpenSCAD. For installing,

sudo apt-get install openscad

Another difference is that you write a programming language to do your
3D modeling. “I’m not a programmer, you say!” Actually, OpenSCAD is a
declarative language, like HTML. If you’ve ever written a simple blog
post or email in HTML, you can handle OpenSCAD.
