I fully agree. As an example, two simple modules with edge segments allow me 
to change between a single board pcb and a version ready for panelizing by the 
fab house.

The attached images show my "cut module", a board using the cut and the smooth 
module. The 3D view shows correct handling of zone filling and the like. Even 
export to freerouting.

I am finding it useful to have edge cuts drawings in modules as well. I have 
just been editing the files with a text-editor to change the layer and haven't 
encountered any issues. Would be good to (re?) enable selecting the Edge.Cuts 
layer in the module editor.

Uhmm... that's new for me... I have the RAST card edge connector which
are *defined* by the PCB cuts and I remember that they are defined in
the module. Maybe it's a restriction added later to avoid some issue?

Also: card edge connectors and holes for reverse-mounted connectors (rare,
but I used them). There is definitely a need for them

Probably there is a good reason for the check... maybe some interaction
from the zone filler and/or SPECCTRA (which is kinda picky with card
edges...).



You're right about the zone filler, it doesn't see internal cutouts so I just 
defined keepout zones over my holes to get what I wanted. It shouldn't be hard 
to automatically define keepouts for internal cutouts as long as you can 
reliably distinguish between the board edges and internal holes.
