Make 2d issue Rhino8.3

Hi.
I get two different results using make 2d command in shaded and wireframe mode. The wrong result happens when I’m in wireframe mode. Also there are little issues in shaded mode.
I tested the same file in Rhino 7 and it was ok there. Is this a bug in rhino 8?


The file:
R8.3dm (680.5 KB)

I could not reproduce that in our in house build. Since you are running 8.3, pls upgrade to the latest service release and see if the issue persists.
