Trimmed Brep with Spheres

Hey everyone!

I want to make round cutouts on a brep. So Ive tried populating it with spheres and then trim but some of the spheres dont cut through the whole body. I could make the radius bigger but thats not desirable. Any of you got an idea how to go about this problem? Did I do it the right way?

After baking ive noticed that the mesh is hollow. Is there a way to fill it up? or fill the cutouts?

Thanks in advance for the help!

Why not try "SDiff"?

That looks way better. Thanks! What would I have to do to change the wave pattern? I lofted 2 curves in Rhino to get this form but I want to see how it looks with waves going Left to Right and Top to Bottom.

Your brep container is empty, but what I did was make a surface parallel/offset from the outside of my real surface and randomly populate this with spheres. Then use the offset and sphere radius parameters to control how much the spheres overlap/intersect the real surface. As long as the real surface is the outside surface of a closed brep the Solid Difference function should work OK.

Replace your 'Trim' component with 'SDiff (Solid Difference)':

Thanks Joseph! Do you know how would I go about filling the holes the spheres have left with a material?

Had to 'Partition' the list of spheres to get this to work.

oh wow! thanks! Can I exclude an area where I don't want the solid difference to be applied? I mean specifically at the top as you can see there are the spheres cut off. Or should I just use the Seed slider to find the right positions?
