algorithmic modeling for Rhino

I am having trouble with surface split. I have a field of breps, and a dividing brep (a series of lofted curves). I want everything inside of the dividing brep to be eliminated or hidden, but everything outside remain.

hi

i guess one of the problem is that your curves_arches are not intersection all of your elements

so one alternative is to cull out the border points of your srf, so you wont get conponents on the edge.

or

scale the arches so they are bigger that the top srf

 In this particular case, i used a cap component, in order to boolean difference them

one solution culling edge points

cool! so can i "uncap" things after the boolean difference has occurred? so that you can see through the holes in the top?

i'll try the cull border points thing first

thanks!

yes, explode them, then cull the cap

btw, in this case (or in my computer), boolean diff runs faster that srfsplit

something like this
