Hello,

I'm new to this forum and to Houdini, and I'm really enjoying Houdini apprentice.
But i'm stuck with a problem, i'm trying to boolean (cookie) a model and boolean this with a scaled down version of the same model. But i would like to have the borders to be of equal thikness, shown in the link. https://docs.google.com/drawings/d/1GsKd3hn2Ym_zX69B1ry2azyLN4fqp7pebSxlfrRgYiM/edit [docs.google.com]

I believe I should scale the entire model along the normals, thats what i would do in blender.

second question, as you can see in the image the model has some bad topology, is there a node to change the triangles to an ngon?

Thanks in advance!

hey William,

to scale a model down or up its normal, try using a peak SOP. also, I could not quite tell the ngons from the picture, but if you are trying to triangulate ngons, you can look into using the group SOP to detect primitives with more than 3 or 4 vertices, then triangulate them or quadrangulate them using a divide sop

If you, instead, are trying to quadrangulate a triangulated model, that is a bit trickier… try using a groupSOP set to edge groups, and group edges based on either their length (generally the mid tri edge is longer than the outer edges) or by angle

hope it helps!

Thx for your quick response,
That peak node is indeed what i needed, but it scaled the sides, top, bottom indepedently.
I used a clean node to get it back to one single mesh, but thats giving a weird pattern on the sides a bit like a saw.

before you use the peak, add a fuse sop.
