If you have too many faces/facets, try decimating the model in your favorite mesh editor.

If you know what units the mesh model was exported with, set the units in this SOLIDWORKS dialog box to match. Graphics Body is often the default, and it is mostly useless unless the desire is simply viewing the mesh model. You'll usually want to set the Import As option to Solid Body. Or enter a loop where each fix causes previously repaired errors to return. relying on "autofix" will often make the model worse. Repairing errors takes skill even in expensive programs with "auto fix" tools. Here Magics detects several errors in the mesh: Use the tool you are most familiar with, and repair any holes, flipped normals, or other defects found in your STL mesh model. You might have your own favorite program like Meshlab, or Blender. I like to edit STL data in Materialise Magics, or Design X. If your STL mesh is terrible to begin with, the resulting CAD model is also going to have defects. I'm making a new tutorial to give additional information. There are several tutorials which already exists for this topic.

Need to convert an STL (or OBJ) file into a "real CAD model"?
