Just throwing my 2 cents in here.
I tried the Bobcad demo and didn't like it.
I also have Turbocad version 12 I think and didn't care for it.
Like many of the Autocad clones it forces you to think their way and I much prefer to just draw.
My current line up is Viacad for the cad side. I just picked up a second copy of the 3d for $69 dollars on sale for a present for my son.
For the cam side I have been through a bunch of trials but since I already own it and am familiar with it I have been staying with Deskcnc.
When the money becomes available I will most likely migrate to Onecnc xr3 or whatever the current version is when I purchase it.
And although I have Deskcnc for my cam software and I use the controller part for my router, I use Mach3 for My mill and will be using it for my lathe.
Mike
