Defining a metal area/route obstruct for an external feature

I have a common situation where a board is mounted in a metal chassis. The metal may simply contact the edge of the board or it may be formed to retain the board, or it may just come close to the board.


How do I define that feature such that clearance rules (copper and part) can be applied to it?


I can achieve this by creating a cell with at least one pad and adding metallisation features, but this is at best a very messy cludge.

Or I can draw the feature, then manually create a route obstruct at the appropriate distance, but this is also a very poor solution.


So how should it be managed with Expedition?
