How to modify an STL or mesh - 3D design for 3D printing pt7
To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.
In this episode, we look at situations where a model has already been designed that we want to modify, but the author has not made source CAD available, so all we have is an STL. Onshape has improved its functionality and it’s now possible to add and subtract geometry from STLs and other meshes. We also briefly look at working with a 3D scanned mesh.
