looking for download source for .pat files

[vanderloo5]

Hi,
The only download source I've found for .pat files is RevitCity.com but they are very limited and don't have what I want. (a dimensional composition shingle pattern). Does anyone know of a good source.
Thank You

get hatchkit. thats the best way. there are also lisp routines you can run in autocad, but there are some limitations.
