Hello, I already asked the support but we couldn’t improve the performance from rhino. Maybe you guys know a sulution for my problem. Im creating a pattern with around 12.000 spheres. With that many objects rhinos performance gets really bad. I can’t boolean difference all objects at once and even …

[Screenshot 2025-09-22 141330] i I cant upload the file because its to large but a screenshot could help

Try to block like 100 spheres together and use that to repeat

That is going to be a challenge with the complexity of the single object that spans all the spheres. For such a structure I might recommend: Create a tile that include 1-4 spheres and a small section of the large surface. Then array the resulting tile to get the size of the fina object needed. F…

are you doing dimples or holes? [image] Help pls - beginner perforated metal Grasshopper – Dale [image] Brep Faster Holes? using AddTrimCurve? Scripting Hi @david.birch.uk , You might trying add each planar curve as …

Im doing holes. And even after the boolean difference the performance doesnt improve

Thank you. I will check out the plugin. Does that improve the performance after the boolean difference?

Hi @Jan_Rücker What is the end goal? Are NURBS really needed or could it be a mesh solution… or even displacement mapping? If this is not for production/tooling, but “merely” for visualization or 3D print, I’d go for meshes instead. -Jakob

Hey @Normand . The end goal is for production/tooling but on a DLP-Printer. I created a different pattern which I can’t show here and its used for a lithophane. The pattern doesn’t even matter that much, more how i can improve the performance.

Hi @Jan_Rücker OK - I’ve been there (eg. years ago working on a perforated door for an industrial CPU unit), so I feel your pain :grimacing: There’s no easy solution, I’m afraid. My experience is that it’s easier to work with curves as long as you can, and when you have to go 3D, don’t use booleans…

Hey @Normand thank you for your help. I’ll try that out. I was wondering if i did something wrong and im always open to improve, but good too hear that professionals also have the same problem and i can’t do much about it I also stay in only one viewport. That also helps a little. Best regards, …
