I am attempting to convert an .obj file to a solid body so that I can edit it in solidworks and add it to an assembly I am creating. I have run into a problem where the mesh file will only be shown as surfaces. There appears to be some open contours and intersecting surfaces which are making it impossible to convert to a solid.
I have tried running import diagnostics, but solidworks is not able to repair the errors. I also tried converting the file to a solid with meshmixer, but there are still problems when I try to select surfaces.
There are two files which are almost identical. The first one, "yy desk", I am able to open and convert to a solid. The second one, "... with chair", has a slight modification but cannot be opened. Can anyone help me repair these surfaces so that it can open as a solid?
