Internal offset - External

1

offset = -1.80 (negative) —> polygon internal offset
offset = -1.80 (negative) ----> External offset polygon

How can I see if offset it is inside or outside?

You can compare the curves length. Longest curve = positive offset, shortest curve = negative offset

Hi, Have a look at spring nodes and the offset+ node. May very well be what you’re looking for.

I had not thought about it
