I have a list of points generated from previous steps.
In general, I have groups of 4 points in a same plane > Make closed poly-lines in each group > Offset outward those poly-lines.
However, I can not control the offset direction at final stage.
Any advice would be appreciated!
Thank you for your time!
Unify curve directions according to the given planes should work.
