Hi everbody, I'm using grasshopper to calculate the GFA of a tower we're working on. The shape of the tower wasn't generated by grashopper and is a fairly complex polysurface, but perfectly closed (no gaps). It´s set in grasshopper as a Brep, and then I used this very simple setup to make sections for the floorplates. The strange thing is actually that it works for almost every floor to create closed curves for planar srf, except for some. When I take the same sections by hand in Rhino, all curves are perfectly closed. Anyone an idea how I should solve this? I know you can test whether curves are closed or not, but I have no idea how to actually close them... I should maybe do something with selecting the endpoints I guess, and then creating a line between them...
