Eliminate elements from a list

[simonnpro]

Hi all,

I have a surface on which I am projecting squares. I want to eliminate the squares that are not fully projected on the surface. I tried to do this with a cull pattern but this doesn’t seem to work

• How can you implement an if-statement in grasshopper?
• How can you eliminate Invalid Breps (in this case) from a list?

Cull pattern is a list a true false values. In this case (2 values searched) you can use a Cset Component or Match Text
