Hi all
I am looking for one hour now online to find a model perforation pattern but for some reason, I'm unable to. Does anyone have one?
I'm not looking for a specific size at the moment, whatever you guys have available will do for now as I am in a hurry.
Thanks in advance.

What kind of component is it that you are trying to model? What kind of perforations are there? Is it in a solid, sheet metal, etc? Unless we know exactly what it is that you are trying to achieve, then we cannot provide / suggest / point out a solution.
Why not use a material with a cutout?
...See the material asset "Brass - Satin Screen" and look at it's cutout.
I'm with @barthbradley. Create a material and give it a cutout. Open any one of the Brass assets. Duplicate, rename.
Switch metal type and finish, check Cutouts, select the Type, size and spacing.
A caveat to the solution posted in my previous post - the cutouts will only be visible in a realistic view. If you would like to see it in a hidden line view, then you would need to add a fill pattern to the surface pattern for the material.
This is actually what I'm looking for. I need it for producing drawings, not 3D renders. So Hidden Line is what I use. The only difference that instead of hexagons I'm looking a pattern with circles.
Interesting. I've never seen a hatch pattern with circles. That would be a real booger it write. If you find one though; please post it here.
...check out Hatchkit @ https://apps.autodesk.com/RVT/en/Detail/Index?id=3030278704485778018&appLang=en&os=Win64
Here you are. I have attached a RVT with the hatch applied to a wall for research. You can apply that material to whatever you need it for, and a PAT file.
Circular enough for me - beats nothing.
Unlike you, @barthbradley - I am easy to please.....
Difficult to please? Moi?
...check out this pat file for one circle. Ain't Hatchkit grand.
I'm using your perforation model fill-pattern. Thanks for posting. I've generated a perspective view with hidden line in Revit. The perforations display as a black mass and no individual perforations can be distinguished. I've tried re-scaling the 3D view to make it very large but still no detail can be made out. Is there a solution to this problem? Thanks.
Hi @Anonymous - can you share a trimmed down file with a piece of geometry that shows this behavior?
If you look at all my previous posts in this thread, you will see that the pattern needs to be applied to the material as a surface pattern, and that the required cutouts will only be visible in Realistic view. If these steps don't work for you, then please share a file to be looked at.
Hi again @Sahay_R
Thanks for your reply. I have applied the hexagons to a floor as a surface pattern. They do display nicely in realistic view. They display in hidden line in plan view too (at 1:10, and zoomed in close). In perspective and hidden line they display as a black mass. My question is to whether it is possible to have them display in hidden line view in perspective. Do you know of any way I can achieve this or something similar?
Attached is a trimmed file. Please see the 3D view named "Perspective".
Thanks again, I really appreciate your time.

Revit will automatically turn off model hatch patterns if they become too dense in a view. What you tried, (scaling up the 'real world' dimensions of the perspective view) is the correct way to combat this, but the size needed for your PAT file size won't resolve this (the view would have to be huge). This is simply cause the hexagons are 16mm across... this is incredibly tiny. You can test this by loading in a larger pattern then seeing it show up.
Not much help, just how it is ![]()
