I sincerely hope the government makes a razzia on your headquarter, seize your computers, send the names of everyone you helped cheating to their schools so they can be expelled, and that you are jailed for helping them cheat.

You are scum.

Thanks for this!

With time some upgrade maybe, to make it work with groups and comps also? ;)

Works a treat!

A sloping, curved driveway converted back into a 2D polyline in a jiffy.


Works great for me. I have always had a problem with that part of my workflow.
Now it is fixed. Thank you for your work.

Hi Eneroth,

is it possible that it doesn't work with curved lines? I have some issues with it in SU2017.

Thanks for your reaction,

SketchUp behaves weirdly when moving individual vertices in curves (the curve gets stretched very far out of the plane). However the plugins should explode the curves before moving anything, to make sure even curves end up on the right plane.

in 2017, plugin doesnt seem to do anything. Shame!

It should work. Do you select edges/faces before running it?
