From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Well my dad basically needs something to make his own custom designs as well as cut costs. He will be 3-D printing them using silver and gold since that is his primary business . We wont be 3-D printing at home tho. He has people who can do it if we have the design in .stl format with much better accuracy. Ofcourse setting the dimensions would also be a problem i think in blender. he says he will be designing earrings and pendants, nose rings etc whose designs we buy from other people. I searched around a bit and found that rhino would be more suitable but it's paid plus proprietary and there's no guarantee it will run on linux with wine
I've decades of computer experience been working with 3D on and off for years. IMO, there's really no magic bullet solution that will likely offer the level of quality and detail he needs given his experience level. There are of course other 3D modeling softwares out there, but for something like custom jewelry I don't expect they'd be much easier to pick up than what you've already tried. However, a combination of tools might do the job better for him:
If he's good at math, then you might instead consider a mathematical based modeling software such as OpenSCAD to build components by formula/code, and then maybe Blender to put stuff together. OpenSCAD has generally been my go-to fit designing parts etc with known dimensions.
A third option might be a good 3D scanner, turntable, and modeling clay etc. He could create the component pieces as real models, scan to a computer for, then touch up, combine, or modify the scan results to build a final product.
Last suggestion, even if he won't be printing the final product, it may be a good idea to pick up a small printer (depending on the size of the jewelry) that does decent detail, so he can do mock-ups and see what things should look like. Even given the cost of a printer (which for a decent small one shouldn't be onerous), catching a flaw in a model done in plastic is probably going to save you money in the long run if you catch it before it gets to the silver and gold stage :-)
As I said, I don't know much about designing jewelry, so I'm probably missing some subtleties. I've had a look at Jewelcraft, and it looks like 90% of what you need to know is standard Blender. Once you start adding components to your asset library it looks like it becomes quicker and easier too. Blender can certainly handle settimg the dimensions on parts, and exports to STL ready for printing. If Rhino feels like a better fit though, they do have a 90 day free trial, so you could see if it works under Wine. It'll have just as much of a learning curve as Blender though, and your likely to find more help for an open source system like Blender.
