Offset one edge of a polygon using cartographic representation
I'm working on a map with a polygon with one edge that runs along a main highway in the DRG base below, obscuring the highway from view. Is there a way using cartographic representation to move/offset only the overlapping portion of the polygon from the highway while leaving the rest of the polygon boundary in its original location? I'd rather not edit the geometry of the polygon, which should extend to the centerline of the road.
Mapping Center Answer:
Yes. Once you've converted the symbols in your polygon layer to representations, you can start editing and select the polygon you want to edit, then follow these steps:
- Show the Representation toolbar
- Using the Lasso Direct Select Tool (the white pointer, rather than the solid black pointer) draw a loop around the vertices you want to move.
- Using the move parallel tool move those vertices away from your road.
- Save your edits.
The result is a what we call a geometry override, which is applied only in the representation rule you created, and does not affect the underlying feature's geometry.
