I have often a trouble when i'm drawing a facade with spline and clipping area (extend X/Y size to area enable).
Sometimes, i dont know what is wrong with my spline, RC doesn't exclude some spline.
RESULT : I cant make a hole on the facade.
However, my spline seems clean : when i put a shell modifier, the result is good.
I tried some tips like :
- Make first some vertex of spline
- Reverse some spline element (specialy the windows holes)
- reset xForm
But often i get the same issue...
May be i do some wrong choice in my workflow ?
