gEDA-user: [Patch] pcb Added ActionSetMaskGap for setting solder mask gap

[Bert Timmerman <bert.timmerman@xxxxxxxxx>]

Hi all,

This patch is as requested in:

http://archives.seul.org/geda/user/Oct-2008/msg00088.html

I don't know if this is *exactly* what DJ meant but it works for me.

This action sets the gap to the desired value whatever the former gap
distance was (this action even accepts negative gaps, that is, mask
overlapping the area to be wetted by solder, for if you want tented
vias).

Just my EUR 0.02

Kind regards,

Bert Timmerman.

Subject: [PATCH] Added ActionSetMaskGap to allow for setting of a solder mask gap for [Selected, all] pins, vias and pads.

Sets the mask gap between the pin/via or pad edge and the mask edge, of all
or selected pins and/or pads to the required value.
What you can do is this:
* Enable the mask layer.
* Select everything that needs the mask distance value.
* :SetMaskGap(Selected,8,mil) to change them all to that amount.
For all pins, vias and pads to set the mask distance you can do this:
* Enable the mask layer.
* :SetMaskGap(8,mil) to change them all to that amount.
