Hi everyone,
I am struggling with a parametric design for 3D printing. My goal is to create a hexagonal pattern within a circular boundary where I can independently control:
-
The Radius of the circular boundary.
-
The Wall Thickness of the hexagonal cells.
-
The Extrusion Depth (height) of the pattern.
My Problem: I have managed to generate the hexagon grid and the circle. However, I cannot find a reliable way to “cut” or “trim” the pattern so that only the hexagons (or parts of them) inside the circle remain.
I’ve tried Region Intersection and Solid Difference, but I often end up with the full rectangular grid or the operation fails to produce a clean, closed solid (Brep/Mesh) that I can export for 3D printing.
Thank you for your quick answer!
Next time i will attache my file.
Have a great day!
is it possible to controll the thicknes of the hexagons?
Yes. Why wait until next time to post your GH file?

good point.
oh ….
I used your steps instead because they’re much easier than what I tried. Could you explain how to thicken the mesh so I can use it for 3D printing?
I’m not going to ask again for your GH file.
Amazing! Thank you so much, I’ll try to wrap my head around this. I’m still quite new to Grasshopper and many components are not clear to me yet
It’s much easier to understand with a working GH file 
P.S. Without the GH file, expressions can be difficult - so here they are:
As recommended on the guidelines page, posting an image along with your GH file can be helpful. Ignoring that page is considered rude by many - including me. Study it
Thanks for the heads-up — I’ll make sure to read through the guidelines and follow them going forward.
