I have code that creates a clipped viewport from a polyline using the command MVIEW. It works quite well on AutoCAD (Electrical) 2018. The only problem is that it does not work with AutoCAD (Electrical) 2016. I have a requirement that this code work with AutoCAD (Electrical) 2016. So I will need a visual lisp replacement, I can only seem create a rectangular viewport using vla-AddPViewport, however, I need a clipped viewport.
