The surface on the left side which we generated with gh and on the right side which we made in rhino by ourself. but when you turn on PointsOn we still have to deal with the untrimmed surface. we already tried ShrinkTrimmedSrf but that did not help at all. we need it like on the right side because we need to work on with the surface to make the structure of the roof. can you help us with this problem?
