Well, I wrote some little C programs that read in a file of X, Y pairs
and output
useful G-code programs. One generates 3 files, to spot, drill through
and tap
the holes. You answer a few questions about depth and feedrate for each
operation.
If you are only drilling, for example, you just throw the extra files away.

I also have a program to do regular grids of holes.

So, I never use a CAD package for these simple tasks. The G-code is
so simple you can write it yourself, too.
