Hi ! I’m looking everywhere to find how to do this : it’s a hatch (no grasshopper) made of dots with a variable density that adjusts to the exterior line chosen to define hach surface. do you know how to do it ? a .pat file ?
Thank you very much !!
Hi John -
Is it a hatch in a Rhino 3dm file? Or in a different program?
A hatch in Rhino is a simple repetitive pattern that can be described in a simple text file. It has no awareness of its defining borders.

Thank you very much for the response wim. I was also surprised but yes it is a hatch : a .pat file apparently working on rhino but i do not have access to it. That’s why i would like to find an alternative solution.
If your screenshots are from Rhino, then you do have the hatch pattern definition.
Hatch patterns are stored in the 3DM file.
In File > Settings > Hatch, you’ll find the patterns stored in the file.
Thanks but the screenshots are not mine, that’s the problem : i don’t have this hatch…
The only way I can think to “fake” that effect, would be to offset the boundary in, and make 3 separate Hatch applications, with the one closes to the border the most dense, and the one in the center the most open. Then Hide the 2 inner boundary curves.
I see. Thank you very much. I hope to find a better solution though. Seems strange this can’t be made automatically ? Maybe it is possible with grasshopper but that’s too complicated for me X)
Seems it could work with something like that. I choose the two polylines as geometry. But :
-I don’t know how to make grasshopper choose the edges of both to only fill what’s in between them and not the two polylines.
- I don’t know neither how to densify the edges and not the points to be homogeneous inside all the polyline. I guess you know how to use grasshopper better than i do
I know this is an old thread but arrived here from google, and so for others, the above images come from this website:Stipple Hatch (not Rhino). In the end I got a similar effect using this grasshopper tutorial https://www.youtube.com/watch?v=VUHD8AkHtcg and adding a bit of a random wiggle to break up the grid
