I'm using CircuitMaker 2000, a layout program a quarter of a century old, but it's served me well for dozens of designs. I've never had a problem sending the program's Gerber files to fabricators, but recently I'm being told that "...your .DRL file doesn't call out the hole specs." The CircuitMaker manual claims that Excellon gear looks for a .TOL file for hole diameters, and sure enough, that's exactly where the hole sizes are. Does anyone know why "offshore" PCB shops aren't able to correlate the .DRL and .TOL files?
