I use Rhino 6 for the 3D prints and Coreldraw for 2D prints.
Tinkercad was the first program I used for 3D prints. I think it was a bad choice because the design/create process is not like the ones used in the better CAD programs.
Coreldraw I have used since its inception. But it has changed in many ways I don't like to complete with Illustrator.
