Squish command

I was looking over the Squish docs (http://wiki.mcneel.com/labs/advancedflattening), but couldn’t find anything regarding the curves or points that Squish is asking for. When I run Squish on a surface, it asks me to ‘Select curves or points on 3-D shape:’ - what curves/points should I be giving it?


you can select curves on the surface that you want to squish along with the surface… if you just want to flatten the surface, you can press enter at that step without selecting any curves or points.

you can also select surface edges at that step… when the surface is flattened, the edges will be curves.
