Offset tool in layout

Hello all.

I use the offset tool a lot to pull a halo outside an irregularly masked viewport - i can fill this with a hatch to create a poche for wall thicknesses.

when the offset path intersects with itself, as it often does, i get an immediate crash. this is troublesome. the offset in sketchup intersects with itself no problem; it would be nice if layout could manage the same.

thx jeremy
