Ok so I have been trying to find a solution to this, but there does not seem to be any deffinitive answer and I feel like it should be pretty simple.
I come across this problem alot when I try to create a kerb and gutter for a road. I basically create a plan for the road, then do and edge extrusion up, then an edge extrusion and scale to create the top of the kerb but the scale is proportional to the length of the edge not the distance perpendicular to it.
Is there anything internal to blender that can do this, or even a paid addon?
