Trying to pattern fill a standing seam roof. It fills the viewport around the roof but not the roof itself. ? In other words the background gets filled with the pattern. Is there a way to select the roof… within the viewport?
If you want to pattern an area in layout you have to trace around your shape and then assign it a pattern in the shape properties. If you have a roof in SU check out Vali Instant roof tools and you can model the roof spines in SU at light speed.
