hatch22 is a Revit addin that helps with the creation of Pat files and fill patterns.
Historically these pat files had to be created by hand. A painful process at best.
With hatch22 you can draw your pattern directly within Revit and hatch22 will convert it to the closest lines that will repeat evenly and will create the pat for you.
