    The definition of 2D is that all the lines are coplanar. It's impossible to make something 3D into 2D without projecting to a single plane.

    BTW, Inventor and Fusion360 both have a command for projecting anything to a 2D work plane. In AutoCAD, in the "3D Modeling" workspace, Surface tab>Project Geometry panel, there is the PROJECTGEOMETRY command that can project to a ucs or view. The FLATTEN command might be able to do it, but could produce an undesirable result.
