2D Hatch
From the Plan Elements area, users are able to define a hatch pattern for the Linear Path in a 2D Plan view.
Hatch patterns applied to multi level surfaces in Revit often become fragmented when viewed in Plan. Applying a pattern to a region overcomes the fragmentation along a multi level surface.
The Overlay Region tool can be run independently of the Linear Path command to mask the breaks in pattern on triangulated floors.
