I have a 2D pattern of a bunch of tiny holes that I would like to extrude into 3D, but because of the number of spots I have, the extrusion takes a long time. I wonder if there’s a more effective method to extruding other than extrudecrv Also, what would be the recommended method if I would like to…

Well, if you imagine why the simple extrusion takes so long - there’s a lot of calculation necessary to create one single surface that has 68,540 edges - which is what the top and bottom surfaces of the solid have. If you extrude open, it only takes a few seconds to do because all the surfaces are …

I would extrude only one of the squares, get its ID, then use something like this script to place a copy of the extrusion at each square centroid. I created an extrusion of one of the squares, it’s ID in my document is e829d7e8-4c32-40bc-a821-495276c8860b. I moved it off to the side. Then I selecte…

Thanks, Nathan, but to clarify, I want the reverse, I want a solid with the curves as hole openings. I tried booleandifference the square extrusion, but it wouldn’t finish. breaking the patterns into squares, I’m able to create surfaces, but then trying to extrude+join them together takes forever… …

Normally, the fastest way (IIRC) is to create a planar surface from the curves and then extrude the surface. Unfortunately, this number of curves is still too much for Rhino, trying to create the planar surface directly or trying to split a rectangular plane both hang Rhino for a long time. (By th…

It does actually finish by extruding with the normal Extrude (solid) command, I have no idea how long it took, as I just left it running this afternoon and forgot about it… Let’s see if it will let me upload it here. Ahh, looks like it did: 2DpatternExtruded.zip (9.5 MB)

[image] Helvetosaur: So, I tried it in the V8 WIP using the solid extrude ball and Rhino simply thought about it for awhile, then gave up. Well, sorta, it actually MOVED the curves up the extrusion distance without actually extruding anything. (This is a bug @wim ) Thanks, Mitch. I’ve added …

Thanks, I guess I need to be more patient when working with large amounts of curves. If I now want to deform/twist, the extruded shape, would you recommend starting from the curves by using flowalongsurface + split, or cageedit on the extruded shape? or is there another method?
