Hi everyone, I want to create a set of stl files (my goal is to 3D print 3 separate parts). So far, I have a set of 2D drawings that I have made. So I'm wondering, can these be used to create stl files ? Would these need to be isometric drawing(s) ? Also, I see that Draftsight can export dwg files converting them to stl files, but whenever I try, the stl files are non existent ???
