Insulation Hatch

I need to find an insulation hatch file for Rhino 7

Dear Verda
welcome to this forum.

what exactly are you after ?
maybe do a (hand drawn) sketch

rhino 7 can import autodesk .pat files.
there is already a lot of topics for this - see links bekow.

check those resources and tell us what you miss.

hope this helps, merry Christmas, kind regards - tom
