Hi Gary.
I use it for all sorts of 2D/3D cnc work.
I've made quite a few moulds from stl files and one of the nice things about CamBam that I find very convenient, is that it's able to cut one from the actual solid model itself. So no messing about, by having to subtract the positive to get a negative.
In case you didn't you know, it has 40 trial sessions (over any length of time), so you could grab a copy and have a play at your leasure.
Like MoI, it's also got a friendly, well behaved forum.

Martin.
