Seeking Advice on Free 3D Design Software

[jland]

I just bought a used ShopBot PRT 24x32. I want to use it to make necks and tops/backs for archtop guitars and mandolin family instruments. I have been researching several free 3D design software options. At this point this is just a hobby and I don't want to jump in at $1000 (Rhino) or (much) higher for other packages.

I've looked at SketchUp, Blender, 123D Design, among others. Each has its own learning curve, and I am prepared to spend the time to get to know the software I pick (I am a software developer by trade, and know the importance of knowing how to efficiently use software tools). But I want to make the best choice possible up front so as not to waste time going down a path that may have pitfalls not discovered until much time is invested.

I already have Partworks and Partworks 3D and plan to use PW3D to create my toolpaths.

I'm seeking advice from others who may have been down this path. Specifically any recomendations on free (or very inexpensive) software and its suitability to my intended purpose. I want to try many designs, but most everything is going to have a similar profile (e.g. archtops and necks) so I don't expect to be using all of the myriad tools that are involved in most 3D packages.

Thanks in advance for the advice I hope is forthcoming.

Jim,
Sketchup requires an extension called "curviloft" in order to execute the forms you describe. Both are free - I produced a carved stool seat in solid wood with it, but not certain you'd have the control you'd want for the described work. I gave up practicing with it and put Aspire on my wishlist, as it appears much more attuned to producing the organic forms of a wooden instrument.

That being said, give yourself an hour or two with Sketchup and curviloft, and you'll have a good idea if it's to your liking, but I'd stop short of recommending this approach and defer to others' responses regarding the other free 3D's. Hopefully someone can give us both an enthusiastic recommendation towards a more ideal product.

Try Autodesk's Fusion 360. Sign up as a startup and it's free.

Gerry, great suggestion, I had not seen this before. I'm going to explore further. Thank you!
