Default Spint Layout into Gerber

I am designing a pcb using Spint Layout. But since I want to order my pcb's from Seeed, they need gerber files.

I know there is a gerber export option in Sprint Layout, but can't find how to create the particular files Seeed wants - GTL, GBL etc.

Can anyone help?

Top layer: pcbname.GTL (K1 - Copper top)
Bottom layer: pcbname.GBL (K2 - Copper bottom, NOT mirrored)
Solder Stop Mask top: pcbname.GTS (Soldermask top)
Solder Stop Mask Bottom: pcbname.GBS (Soldermask bottom)
Silk Top: pcbname.GTO (B1 - Silkscreen top)
Silk Bottom: pcbname.GBO (B2 - Silkscreen bottom)
NC Drill: pcbname.TXT (Drill data)

Then you simply can rename the files.

So, for each layer that I have created with Sprint, I just export it to Gerber file and then rename it, right?

And, what am I supposed to do about that drill data?

The GTL and GBL etc extensions they ask for are just their naming convention, so you just need to rename the Gerber file output from Sprint-Layout to match their requirements.

Email them if you are not sure which drill options in Sprint-Layout to use. I usually use 3.2 metric, but that's with other PCB fabs.

Thank you!

I see. These drill options have to do with standard holes that they will have to drill? I mean, the holes I will specify in my files should be a standard size chozen over a certain known range? Is this what this means?

It's not that, it's the format the NC drill info is written in, the way the XY coordinates are written in the file.

PCB fabs will have a range of drills so there shouldn't be a problem. The only thing that might come up is specifying metric drill sizes and sending the Gerber to a fab house in the USA where often imperial sizes are more common. That said, even they are starting to use metric a lot nowadays.

Thanks for the answer! I also use mm.

And how do I get this information out of Spint Layout?

Oh sorry, I was talking about the drill information, I know about Gerber export.

How do I make it into the text form wanted?

So I would like to order some pcb's from seeed, and I am a bit confused about how I should order a single copper layer pcb.

My options are:

Solder side (bottom) consists of : copper layer, soldermask + silkscreen, and:

(1) Component side (top) has only silkscreen.
(2) Component side (top) has through hole pads that come from the solder side (but no copper tracks), soldermask + silkscreen.

So, how do I implement the 2 options? Seeed asks for every layer (so how could I specify that I need no soldermask and copper, for case 1?). For option 2, I assume I just have to choose the option saying "through pad" for pads. Correct?
