Me understanding drafting pattern doesnt help the fact that revit has to go for autocad or plugins to create patterns
You can write your own hatch pattern definitions as well, using any text editor, such as Note Pad.
Here's one (units are in inches):
*My Hatch Pattern
0, 0,0, 0,.25
0, 0,.125, 0,.25, .125,-.0625
Copy it to a Note Pad file, save it as a .pat file and use it to create a custom Revit DRAFTING Hatch Pattern. Know how? If so, test it. You'll see.
Here's one tutorial I found for you on-line that describes the fundamentals of how to write your own Hatch Patterns. There are others. Just Google search for them.
