Direction toward the inside boundary of a surface?


Is there any node that allows me to always get the direction toward the inside boundary of a surface or a close loop? Thanks


Offsetting closed PolyCurve with negative value should move lines inside the shape.

If this somehow fails - you can offset face perimeter in both directions and take the smaller one.


Thanks for your reply Tomasz
Yes, input a negative number works, but it only work when offset the close loop. but what about just offset the edge I picked?


Offsetting lines tends to be very inconsistent. The below example is not very straight-forward but the Geometry.Translate node seems to be she surest way:


Something like this?


This is Awesome :+1:
