Hi, a client sent me a STEP file and when I open it in MoI, some of the surfaces that create a thickness aren't trimmed properly. The model is sort of a pipe and you can see some thickness at the bottom of the image, but it doesn't continue around the entire opening. The model imported small so I enlarged it 100x, hoping to retrim the surfaces, but the trimming edges seem to be missing. I want to look smart for my client. Is there something I can tell them to do in SolidWorks that will create a STEP file that I can use.

Thanks if you can help me!
