I work at a theatre centre, and I need to convert some simple 3D drawings into 2D. These need to be converted into objects, as that is what my supervisor has requested. I am not allowed to do this via viewports. When I attempt to use the "Convert to Polygon" / Hidden line mode, I end up with several hundred thousand objects. I need a simple way of converting these 3D objects to 2D polygons. Advice would be appreciated. Thanks!
