I also know that it is possible to get an AutoCAD pattern and use it in Revit, but. Sadly, I couldn't find a ridig insulation pattern in there either.

I can reproduce this now with some hatch patterns i got from AutoCad. The only way to scale them smaller was to change the hatch scaling globally under: Document Properties / Annotation / Hatch / Hatch scaling If you click the Hatch scaling button, then turn on “Enable hatch scaling” and reduce the value from 1 to eg. Downside is, you´ll have to scale up all other hatches if you have one to keep them unchanged., I´ve also notes some strange behavior once above is done, Rhino seems to slow down drastically when i try to change an existing pattern to another one.

Lets try your help. I see I need to change the global hatch from Options Menu and then tweak the hatch scale? (now i understand) But this hatch wont work like cad, on the same line. Rhino full fill the boundary area with a pattern and not like cad with only a line, in this case which is a batting line!? Another question.

And i found that, if i try to export Rhino to Illustrator That Batting Hatch wont be recognized bi illustrator. Either files export from Rhino, or Illustrator import Autocad hatches. Do you have some knowledge on this matter? Thanks for all your help.
