invert tstop bstop soldermask layer

Create a polygon in layer 29 (tStop) with the size of the board.

Yes but thing is, cutout option for polygon doesn't seem to work on the tstop layer...

Quote from the manual: "Only polygons in signal layers can have the pour style "Cutout"."

I wonder why...

You may be able to do what you need by using

copy-layer-to-any-layer.ulp

If you can get the stop polygon the way you want it on a copper layer you

can use the ulp to copy that polygon's contour and fill wires to the stop

layer. (Then delete the polygon on the copper layer)

It may take  bit of trial and error to get solder stop where you do need

it.

I tried your suggestion and the ulp does exactly that: it copies the polygon shape to another layer. It still does not work for what I intended to do, since the "cutout" attribute of the polygon on the copper layer is not copied. It therefore still simply draws a solder stop shape on the stop layer instead of cutting out a shape.

It looks like it is not possible at all, as the quote from the manual discovered by Joop14 suggests. It doesn't seem such a far-fetched idea though (feature request?)...

Thanks anyways.

Dont give up. It is possible provided I understand your need correctly

Yes. That is exactly what I want. Still couldn't find the right settings in the ulp to get it to work on my board, though.  What settings did you use?

In the meantime, I drew the tstop layer by hand, which didn't amount to that much more work in the end.
