Previously, when modifying a 3d geometry, the third dimension was lost when you move a vertex, replaced by zero. This commit fixes it.
However, when adding a new vertex in a segment, the third dimension will still be zero. Should it be the average between the previous and next vertex?
Keep the other dim from the original segment when modifying vertex
This looks very solid. I hope to have a deeper look the next days.
Is there a chance to have this in next version, we would really appreciate this correction.
Sorry, I forgot about that one. Still looks good, thanks.
