Reddit reviews Inside Rhinoceros 4

Why on earth are you learning Rhino? You'll get a lot farther in the industry learning pro-E or Solidworks. I don't know anyone who still uses that program, and your professor is very behind in the times if he's telling you to learn it, especially at junior level.

We had to "become familiar" with Rhino our first year of ID undergrad, and it was a nightmare. It does not function with dimensions, and you'll end up making something that is "three inches-ish." If you'll be using 3D prints with it, joining pieces will never align properly. It loves exploding, especially when trying to apply a radius or round on anything. Our class ended up creating a folder on our shared drive of screen captures of the crazy things rhino would do when it blew up. And be prepared for crashing.. lots of crashing.. Our university has since dropped it.

If you are hellbent on learning it though, try looking for downloadable ebooks/text books like Rhino for Jewelry by Dana Buscaglia or Inside Rhinoceros 4 (try to find them for free; not worth buying ..) Even though the first one is jewelry, it's for beginners of the program, so it'll help you get used to the commands, etc.

I sincerely wish you the best of luck..
