Hey all I am converting a Proteus PCB design into Altium and I am wondering what each file is since it asks me in Altium.

My Proteus files are:

enter image description here

And this is what Altium does when I do a PCB Design Check/Fix:

enter image description here

And so I say Yes and I am presented with this:

enter image description here

And this is where I am not sure what to put for each... Any help would be great!

I suspect that those are Gerber photoplot files.

Looking at some of the types listed, I'd say cadacam-bottom-silkscreen.txt should be "Silk Bot", ...bottom_solder_resist.txt should be "Mask Bot". Others seem pretty obvious, although you may have a bit of a problem guessing at the valid type names.

The file names seem to me to be self-explanatory, if you have some idea of the photoplot files required to make a PC board.

  • \$\begingroup\$ since _bottom_copper.txt is Bottom, I'd expect _top_copper.txt to be Top. That is, those two layers are the top and bottom copper patterns (pads and tracks) for your board. _mechanical_1.txt may be the board outline - you'd have to view that file to be sure. The silk_screen files will be the text printed on the finished board. _solder_resist is often called solder mask - it is the green coating that covers the board, except where you want to apply solder. \$\endgroup\$ Aug 11, 2016 at 1:13

  • \$\begingroup\$ The cadcam_mechanical_1 file looks like a Gerber photoplot file. You should look at it (and all the other files) with a Gerber file viewer. If I remember correctly, a Gerber viewer was included with Altium. If you can't find it, google for "Gerber file viewer" - there are a couple of free ones available. \$\endgroup\$ Aug 11, 2016 at 1:32

    \$\begingroup\$ Well, yes - didn't I say mechanical_1 was probably the board outline? In the Gerber viewer, you should be able to view all the Geber files superimposed, to show the full board. \$\endgroup\$ Aug 11, 2016 at 2:10
