SplitBrep? and delete one of the remaining surfaces

Hello!! :)

I'm now starting to learn Grasshopper and already encounter my first problems.

I am trying to split this Brep? with a plane and everything seems to work ok. Now as a next step I want to delete the upper part of the Brep and I dont know how. I will atach a screen shot with my approach, a screenshot with my goal and the GS + Rihno files.

Thank you very much

In column01.gh, the loft option 'Cls (Closed)' is incorrect. This is not a closed loft. The 'T (Type)'="Straight" loft option is essential, though, otherwise you get curved surfaces.

ups, yes, you are right forget to undo the closed bool in the hurry, thanks Joseph
