Hi,
I did the Vcarve and they free trial does give you the full power of there app but will not let you export anything you create.
That is the norm with trial versions of CAD/CAM software. I suspect it changes when you buy it. I think you will find
some restrictions of similar nature in Fusion360 as well.....and they to evaporate or at least substantially reduce if you
pay up.
Making CNC parts is a process and its not unreasonable to say that CAD/CAM software underpins the whole thing, I mean
what good is a Mach CNC machine without Gcode programs for it to consume?
I would recommend your current course of trialing all and any software, get inputs from other users before buying.
Every CAD/CAM package I've come across requires considerable learning to get the most from it. You don't want to make
that investment only to realize that its not capable of your current requirements or future needs. The chances are that if you
buy a program you will gain so much familiarity with it that you will be a loyal customer of that company. This is exactly
what AutoDesk want and they cant be blamed for trying it.
