Hi, I was messing around with 3D grids of boxes in the past, as well as low res volumes/vdb but I never figured out how to generate "boxy" volumes, or box grids with interior faces removed, making a compound shape with no interor geometry. Is this generally difficult to achieve? I think my main problem is terminology and difficulty to accurately search for help on the topic. So any help will be appreciated as I try to dive back in! My last attempt was making basic cellular automata with cubes, it gets very heavy if you output a high res grid with all the interior box faces, which you never see anyway. Thanks, Nik

Extracting a curve from the slice of a terrain...

Hi, I have to issue with something that should be relatively easy to do in my mind. There is multiple poly grids in my scene. 4x4 grids aligned next to each other and also merged together. I need to extract curves splice at certain altitudes. When I use the Cookie SOP, followed by Divide and Ends, I always end up with a seam in between each grids. Is there a way to get rid of the seam? Or a better way to make this happen? The goal would be to extract iso lines just like on this image. BUT... I don't need all those lines. Only one line at the height the user desire. http://www.ctech.com/wp-content/uploads/2011/12/isolines-viewer-1.jpg Many thx C
