Exporting to Solidworks issues

Trying to export solid models from Rhino 5 to Solidworks 2019 and every format that I have tried opens up as loose surfaces in Soildworks. There are also misc surfaces that are in the file. See screen shot of the Solidworks file.

Any suggestions or comments on the issue would be greatly appreciated.

Hello - if these are joined in Rhino and the tolerances reasonably tight (?) then via STEP format they should open as solids in SW. Feel free to post a file here or to tech@mcneel.com (with a link back to this topic, please)
