How to put two gerber files together in a single one?

I often desire to keep free from solder mask some areas, as Logo or areas where I need to solder with thin. The system allow me to reserve from the solder mask only the pads but not all I want. So I have to create another layer that I call "Top Mask". This layer is to add to the auto generated Top Copper (resist). How can I do this obtaining a single file?

An alternative (maybe the right way) could be to put the shapes that I need on the layer "Top Copper (resist)" , but: how to do it?

Thank you

If you it sounds like you have already added the new layer (Top Mask). Make sure the layer type is set to Solder Mask in the design technology. Then in the Output > Manufacturing Plots dialog, click the Auto-gen button and select Gerber. It will then repopulate the list of plots in the plots window, and the Top Mask (or something similar should show up, with its settings already set to include the openings for pads, etc in addition to the shape you drew on your layer.
If you include an explicit mask layer when you first create the PCB, I think it will generate the right ones to begin with, without the need for auto-generating the Plots definitions.

Hi Umurri, you can add an exlusion area to the solder mask layer. But first in DSPCB you must create the layer in the Design Technology such that you can edit it.

You can then add shapes to the layer which will be excluded from having resist applied.

Ciao umurri,
1) in "Outputs\Output Manufacturing Plots" if you select "Top Solder Mask" and in the right panel select "Layers" you can select, in addition to the "Top Solder Mask", your one "Top Mask"; may be, does it work?
2) "Add\Add shape" select what you want, then "Change Layer" (or hit "L" on the kb) and select "Top Solder Mask"; may be, does it work?
