I have multiple stl files that need to be imported into one solid works project. This has presented 2 problems for me. The first being the stl files are too large to import directly into solidworks (files anywhere between 2mb and 150mb). To sold this part I open the file in meshlab and export the mesh as obj files. I then open the obj in solid works and covert the mesh to a solid. This solution works fine for what I'm doing. The 2nd problem, which I haven't been able to find a solution for, is how to import all the obj files into the same project. All the stls converted to objs are parts of the same assembly. As mentioned previously I'm able to covert each stl to a solid, but now I need to get all the solids into the same project. Any help would be much appreciated.
