Hello, I'm working with some imported parts from our OEM to create a drawing with our modifications. I've had issues with files from them in the past, but this one has stumped me on how to get the body to appear in the drawing. When I imported the files, I properly saved the IGES files and healed the faces. When I go to add the model to a drawing, it shows up with the proper bodies, but then they disappear after hitting the checkmark. I've tried to insert>model items>surface bodies, but these aren't surfaces. I've gone from shaded model to view to non-shaded, and they still don't appear, but will show while shaded. If I hover over the drawing view it will show me the outline of the body, which is improperly displayed. I've included some images below. Any help would be great!
