I usually draw stuff in Sketchup8. I started to learn Fusion360 until it went web-only and subscription.

I have a gantry type CNC mill, with MACH3.

I want to do some repetitive hole drilling, so I am going to get it done quicker by hand coding the G-code or is there a quick and easy 2D CAD package that is worth trying? Ideally free, or cheap and subscription free?

If there's something out there that can do 3D too, that'd be great.

Just thought I'd ask here before I go googling...

Cheers.
