Hi saltab, for all parallel projections the result from Make2D will preserve scale for lines that are parallel to the view plane.
For the case of an isometric view, the preserved scale will be for lines like this:
If you run Make2D on that isometric view, you should get a result with the 2D projection of that line being the same length as the 3D line, like this:
The other lines will not have the same length as their 3D source lines, because those lines do not have both ends on a plane parallel to the view plane.
That's just the same behavior as Top/Front/Right views, lines that are not parallel to their respective view planes will also not maintain the same length when projected either.
Does that help explain what you're seeing ?
I guess another way to describe it would be that it is preserving scale but it's in a different direction than what you were thinking?
