SOLVED_Map to surface includes previously trimmed parts

Hi all,

Im trying to recreate Brasil cathedral. I cannot understand why the Map to surface command is projecting the pattern even to the part of brep that was previously trimmed by Split brep and selected from list.

Im also curious whether there is a better way to create the ribs. My solution is enlarging the ribs around one point, but the enlargement is limited by other curves (triangles) that Im using to define the lofted shape.

Ideal state would be a point movable along the curve. (With slider-0 as a beginning of the rib, 100 end of the rib.) This point would be defining the thickest part of rib. And the changes would be even up to the end of the rib.

Hi.

It's because your trimmed surface still keeping the original untrimmed surface's UV domain data.

This one(Red parts are my additions) is a roundabout method convert your trimmed surface to untrimmed one.

And you can have more control to your section curves of rib with graph mapper and scaling domain.
