Line offset problem

I achieve the result, as in the picture, that is, I want to make parameters on the roofs of buildings for greater realism…


But I had a problem with the line offset, on the top of the boxes. That is, some lines are offset correctly inward, but others are offset outward. What is tedious to do so that all offset lines are inward?

Hey

There are plenty of answers of this specific question on the forum already ! :slight_smile:

You could either offset in both directions and pick the shortest poly curve of the two offeted poly curves.
Or on your screen, you specify all the planes each poly curves with the component “planar” (“isplanar”) and feed them into you offset component.

cheers
