Hi Michael,

Thanks for the explanation. Yes, save-open works fine. Not as fast as I am used to (I actually go a lot back and forth between Rhino and MoI), but that's fine.

I this example, I created a cube, duplicated the edges, threw away the cube, rotated in 3d, adjusted cplane using the script and then project to cplane. Now I have the lines flat on the cplane, and that I can export the DXF for laser engraving.

But the script I have found only gets me close to that, none of the other viewports are identical to the 3d. Any tip?

Thanks a bunch,
Ditto
