How to add components using loop in Eagle PCB script

I didn't know it could do this, but I've just tried it out, and it works. Here's how I did it.

1. Open a new schematic, or whichever schematic you want to add an existing design to.
2. File->Import
3. Select the schematic of the design you want to add to the open schematic.
4. Make sure the nets are named the way you want (identically named nets will merge)

That's it, I get a new sheet for the added schematic and the completed layout added next to the existing layout.

If this doesn't work for you, it's likely because you're using the Eagle Freeware, not Eagle Standard or Professional. The hobbyist/non-commercial version is not too much if that is the problem and it counts as Eagle Standard. It's what I have.

I've used 2 different methods for scavenging components out of Eagle projects.

Automated method. Run exp-project-lbr.ulp, then sort through the automatically generated library.

Manual method. Originally from here.

1. Select the parts you want to copy with the group select tool.
2. Use the scissors button on the toolbar.
3. Right-click the group or hit the GO button after clicking the cut button. Eagle wants to know what it is you wish to "cut", which is really more like the "copy" command in most apps.
4. Open the new file and do a paste, it should copy the info.
