But my application is a little different.  I want to get a DXF file that I can run through a CAM package, in particular the paste layer, which isn't a 'real' layer, unfortunately -- it is synthesized in the output HID as I understand it.
I somehow feared this while I wasn't sure: so it is not posible to manually define the paste mask on a footprint?
If it's possible, how?
I need this to create the footprint of a part with thermal central pad. The manufacturer recommends the mask should cover 55-70% of the central area while near 100% of the electrical pads are to be covered with paste. The industry std-solution is to "grid hatch" the large continuous areas which also helps to keep the paste in place.
Hand-soldering is a nightmare-option with 0.5mm pad-pitch ;-)
Is it possible to define an offset to the copper area per pad?

If nothing else helps, how difficult would it be, to just create an attribute that triggers a stub that fetches and inserts a handcrafted gerber-snippet from a file instead of running the generator?

Thanks in advance, Armin
