Is this what you want?
This is really nice. Thank u soo much, but is it possible to take out crossed rectangles? as in previus picture I showed.
?.. Turn off the preview of Boundary Surfaces.
The criteria for selecting panels to remove is vague.
I didn’t mean exactly that yellow ones.My basic idea was to make them cutted opening and keep only whole rectangles with removing splitted rectangles
as u can see from this picture theres noo splitted rectangles.
thank you Kim.Its more than my expectation.So nice!!
