Hi David,
If I do a ":ChangeClearSize(Selected,0.2mm)" on one of the vias I get a bottom-mask gerber file, as expected.
Apparently gerbers are generated on the basis of having valid and useful information (must have, not a nice to have).
If no apertures are "flashed" onto the solder mask, then the mask remains untouched, no gerber file is needed for the fab house.
Any pin or via with a non zero mask clearance would cause an aperture to be "flashed".
Kind regards,
Bert Timmerman.
