SolveSpace

The power of SolveSpace is that the most common functions have keyboard shortcuts. The basic workflow is to create a sketch in 2D, make it 3D, use extrude and set the size and relations between objects. Then pick a surface on your piece, make a new sketch and extrude. The interface is clean and very easy to get started with. The lack of features will probably be a handicap in the long run, making complex forms harder to create, but it is very easy to begin developing on. In SolveSpace’s favour are its assembly functions, a simple but effective way to put pieces together. You can import any file including assemblies. This is the best choice if you want to make spare parts to replace small damaged pieces in your home. The lack of advanced mathematical curves and shapes will not be a problem for most users.
