Problem with Make2D

Hi @GregArden

Please see files enclosed.

I am trying to make a simple Make2D in the top view.

I expect to see a continuous polyline as in the shaded mode.
Can you please have a look at this?

Hi Dmitry - since the edges are exactly coincident with the green polysurface, hidden and visible lines are, I’m guessing, impossible to sort reliably. If you include hidden lines in Make2d, the curves are correct though not all on the ‘correct’ layer. What would be correct here?


Yeah that should work.
