Hi Daniel, Thanks a lot for this trick, it works perfectly! Could you explain how (a*c+b*d)%2 works ? what is the % for ? Is there a way to get the culled faces? Many thanks, Arthur

getting a subdivided surface to react to a distance from a point

Hi again guys,Still a newbie, trying to get a little something to work here. So I have this surface that I've subdivided, I will eventually turn this into surface boxes, but before that happens I want them to react to their proximity to a point. If too close to the point, the subsurface doesn't show up. I think that I am on the right track: I have the surface subdivided. I take the centroid of the area of each subsurface for the first point of a distance calc. I use a point that I define…See More

Not to keep bumping this thread, but I just figured out that a 2-rail sweep with a second rail holding the hand of the section basically does what I was intending - but I'm still curious if there's another workaround for 1-rails or not.

Showoff! Another n00b question: the 1-rail sweep component seems to default w/ freeform. Is there a way to get it to the equivalent of roadlike top?

Nice! Thanks David and Daniel for the quick responses. I've already succeeded with David's technique. Daniel, I'm going to set up a scenario like you've posted and work through exactly what's happening at each component.…

Here's how I get around this : where the expression is (a*c+b*d)%2

Hi Brorstein, Using a Culling component, you can remove specific items from lists of data. If all your items (sub-surfaces in this case) would be in a single list, then a Cull Nth component would generate a checker pattern, provided there are an…

Checkerboard pattern?

Hi everyone,Very new to Grasshopper here - I'm trying to do something that's probably quite simple, I just can't seem to find what I'm looking for.So I have a surface, I've divided the domain^2 and made a matrix of subsurfaces from that. Simple. What I want to do now is select a checkerboard pattern in that collection of subsurfaces. Simply adding a 'cull nth' set to every other number selects whole rows of subsurfaces in the 'v' direction. I know this has something to do with the way the…See More
