I'm hesitant to even ask this question as I know its very subjective and there are a lot of threads out here asking "whats the best CAD for me". I've read through many of those and still don't have a good feeling of what CAD program I should go with. And with the daunting number of choices, not sure where to start. So I'd like some help narrowing down the choices and then download the demos and see what I find the most comfortable.
Here's my story and "needs".
Just getting into CNC machining. Been playing around with the wizards in Mach3 and its working well cutting air and MDF for practice. I have my g-code book and learning that as well. I've also have my CAM software and learning that (SputCAM). I've had some exposure to CAD many years ago and more recently by using SketchUp (the free version). Eventually I'd like to get into low volume production work and making some money at this (at least enough to partially offset the cost of the mill and tools over time). But for now its just a hobby and learning opportunity and something I can teach my kids.
Looking at primarily 2.5d milling for now. Cutouts, pocketing, 2d curves/circles, drilling, tapping (though initially that will be done manually). Maybe design/mill an AR15 lower receiver, just to say I did. Also like to do some lettering/engraving. Likely be working in aluminum, some steel and some wood.
I'd really like to keep the price below $500 if possible, knowing that once I start doing more complex things I'll likely need to take the next step and spend $1-2000 on a "good" CAD program. But that's probably 1-2 years off. So I'm really looking for a beginner CAD program.
I've looked at:
Alibre - tried, nice but talked to a couple machinists who don't believe the PE version is worth it ($250). The next version up is $1000.
BobCAD - the stand alone v25 CAD program without the CAM stuff is around $250, which is within my budget.
Vectric - Cut2D is priced right at $150, but looks pretty basic. I'd be willing to step up to vCarve Pro for $599, but it seems to have more of a woodworking emphasis, maybe that's an incorrect assumption by me?
TurboCAD - sounds OK, and starts around $130
Rhino - heard good things, but again, starts at $1000
ViaCAD - heard good things and starting $100 for the basic to $250 for the "pro" consumer grade stuff
SketcUp 8 - played with this. pretty simple which is good, but I've heard its not really a serious CAD program, at leas the free version.
FreeCAD - tried, ok but needs polish and is only metric (as far as I can tell). Not sure I want to convert my Mach3 setup to metric.
Are there other options I should consider?
