Not Solid, just a "Joined Surface

I now have files that are showing as solids. This is a major step forward. However, if I try to export to STEP, it still separates the surfaces individually. These are hundreds of surfaces in these models. Is there no way to make this work? If I have an MOI file that shows as a solid, is it going to show me the problems that are causing the export to STEP to fail?
