Exclude small surfaces

  1. How can I exclude surfaces in the circles, which are too small?
  2. How can I transform this structure into a penetrated rectangular for the fasade?

You can use Lager Than+Cull Patternto exclude the small circles that have smaller diameters than you want…

If you have a boundary of these circles, you could use Boundary Surface or Surface Split, but since you have a hell of a lot of circles, so you’ll probably need considerable calculation time…

Thank you, I’ll try tomorrow.
