Allegro 17.2 backdrill solder mask export to GERBER

VECTORT

Hi,

I have created design with backdrills and right now I have an issue with exporting soldermask do gerber files.

For via solder opening there is a layer: VIA CLASS/SOLDERMASK_TOP and VIA CLASS/SOLDERMASK_BOTTOM

And that works perfectly but when backdrills are created the solder mask opening is set in layer named BACKDRILL_SOLDERMASK.

But this layer I can be see only in "PAD Editor" in "Mask Layers" tab.

There I can see SOLDERMASK_TOP: none SOLDERMASK_BOTTOM: none and in BACKDRILL_SOLDERMASK: Circle 0.55

And I have no idea how to export it to GERBER files because there is no such layer in Artwork to be selected.

Thanks in advance for any help.

    Thank you
    That worked.
    The soldermask top and bottom should be different than 'none'
