I like to have different folders for different projects. In the bottom of Define CAM Documents dialogue select arrow down next the 'default' and select Create. Give the name of the project and in CAM location it will be a separate folder for that project where Gerber files will go.
Thanks for the quick response. Regarding the Layer information used to Generate the Gerber files, does that get saved with the board (.pcb) file?
Yes. Once you define it save the Gerber setting and save *.pcb and it will be part of your database.
You can also hit 'Export' on the Cam dialog box to save your Gerber settings in a text file. You can use 'Import' to bring this into other designs or it comes in handy if you want another way to tweak things besides the GUI.
I also use an individual folder for each design's CAM. If I was only working on one design at a time then PADS has some nice features if you keep everything in the common folder. Unfortunately I'm often working on multiple designs so I can't have them co-mingling.
If you export your CAM settings, they can be imported into the next design.
One handy feature is that the files is ASCII text. If you have a different number of routing/plane layers, you may find it easier to man-read/decode the CAM settings files and add/delete layers there, then import back into your PADS design file.
You'll find that you need to change the layer number and name in 2 or 3 locations in each layer section to match your Layer Definition settings.
This really only affects your routing/plane layers since your documentation layers (probably) don't change.
Hint: You can do the same ASCII man-read/edit on the *.pdc file that controls the "Create PDF" output!
