Give the new fill pattern a name and browse to your desired hatch file. Create a new Drafting or Model fill as appropriate. Go to the Manage Tab>Additional Settings>Fill Patterns. What I'm really looking for is clay tile roof & asphalt shingle hatches, among others. This simple text file should be renamed as a ‘.PAT’ file before importing into Revit. My question is how can I turn it into a VW HATCH which can fill up an object no matter what it's shape and size, just like the brick hatch I mentioned before. Although it's not what I'm looking for I tried prcatising by 'Add Current To Favorites' & 'Add File To Favorites' but it dosen't show up in the Hatch folder. I have found a dwg file called 'Field Stones', converted into a MCD, it is a bunch of polygons representing the pattern of field stones. What I'd to do is to find new hatches and embed it in my Hatch folder.
I understand, and have used, the process of importing objects to the Resource Browser from other VW files, e.g symbols, worksheets, even hatches(inside the Hatch folder of another file, ready to fill an object, e.g brick in a rectangle).
