Dear Readers:

I am experiencing difficulty with the Cookie and Hole operations. Neither of them give me the result I am expecting which is to take the eye out of the capital letter A so it looks like a correct letter A. If needed I can attach a file for reference. Any ideas what might be going wrong? I played with the tolerance and that didn't fix it.

Sincerely,

“C is for cookie, dat good enough for me!”

Yup, an example file would be handy.

Here's the hip file. Houdini 9.1 .

I even fused the geometry to make sure that nothing was unclosed. . .

the curve in the sop named ‘delete2’ is a bezier curve. You can confirm that by MMB'ing on your sop.

throw a convert sop after your delete2 to convert to polys and you should be off to the races.

Thanks G.

That works somewhat. If there are other NURBS operations that I want to perform on the geometry howevery I have to convert from polys back to splines and that seems to be problematic. I'll have to figure out a hack to simulate what I want. Don't worry, I'll figure it out from here. I was just unaware that cookie or hole only works on polys. In M _ _ _ you can perform Boolean operations on Nurbs as well as Polys.

Hi markerline, Surfsect is the NURBS equivalent of the Cookie SOP.

Thanks, I'll have to try surfsect.
