Dividing buildings into floors

See the attached definition. I made a generic extrusion with two parameters to control the height: 1) floor-floor height 2) floor count. I put a bounding box around this extruded surface and used the first point as the origin of the cutting planes. The two parameters from the extrusion also controls the z-coordinate of the cutting planes. The output is a list of curves. Hope this helps.

Thanks for the help, Tuan! I didn't exactly use your method because the building heights aren't determined by sliders, but looking at your definition helped me understand some of the concepts better. I put in cp origins and they look like they're all set up at the right spots, but when I actually section the geometries, they come out funky. Is it because I've got multiple geometries I'm trying to section?

I cleaned up my definition and re-attached it along with another screen shot.

Use Cross Reference instead of Longest List for you Brep/Plane Intersection component. That should do it.

Ah thanks for the suggestion but it still doesn't work! Sorry to be such a problem child. It divides the breps into many many sections.

I added two data tree components to your definition. See image below.

Ah amazing! Thanks for all your help!! Looks like I've got some homework to do on trees.
