It's a quagmire of good intent, sending you on the road to Hell. It reminds me of someone I know that calls himself a designer, not on this forum, and uses Rhino in the most convoluted, wrong way, yet bangs out zillions of models and complains that nobody buys them. Do not mention that person's name if you know it, just chuckle to yourself. I remodeled one of his works for someone to prove it to them, and also to admonish the ridiculous price he was paying to this poor chap, to get him to make a model he was going to sell ($100 dollars!!!), both were in the wrong. The model I ended up with looked nothing like I was given, and this person could not afford my services, not that I make them available for this hobby, but in the automotive world, it's &75 bucks, cash, first hour up front, and another $75 per hour after that, you do get the Rhino file after that.. That's cheap. If you then want that part made, drop off your first born at my doorstep. Of course, what I do for friends is priceless (mostly free, they supply the materials), I've saved many cars with holes that would have failed inspection with my welders, that's what you do for friends who don't have the means and need their car to get to their job, and that's the big difference.
