Perforated Surface

I made a pretty simple definition, that generates a perforated surface. The problem is, that it takes "some" compute time. The question is:

Is there a possibility to trim the surface with generated circles, or create a curve that incorporates both the surface, aswell as the circles, allowing me to extrude it.

If there is another solution, that will cut the compute time, I will be glad to hear it.

Another question regarding the perforation on the edges. Is there a possibility to eliminate that?

I also would like to know how to eliminate the perforations on the edges please.

I am dealing with perforation conditions also. So far I have come to accept that it must be done manually in Rhino geometry.

What is the end goal of this exercise? Fabrication? Visualization? Other?

If it is visualization and from a distance, instead of creating solids you could use an image map or dark gray circular surfaces.

If for fabrication or close-up detail views, then I agree with Adam, you're pretty much stuck waiting.

I modified your definition to make it a little more robust:

- The cylinders extrude in the direction of the surface normal.

- I've culled the circles along the edges.

- I've added a toggle to compute or not the final solid geometry. Leave it at False while you are working, then set it to True when you are ready for the final solution. I do this occasionally at break points in a long or computationally intensive definition, so that I can deal with only what I need.
