I tested the make 2D feature in the beta build. When i select the object form perspective view. It makes a 2D drawing without the hidden lines. Allso it adds some strange drawings apart from the 4 drawings that it should.
When i do it from a top viewport it does make the correct hiddenlines but they show in black and you have to change the object properties from show display colour to layer colour.
Allso the viewport gets rather slow when the 2D drawings are made.
