I appreciate the compliment. It kind of is easy to be honest. Especially if someone helps you with a basic understanding. Sometimes people try and make what they do seem like they are specially gifted, and no one else can do or understand what they do. They throw tantrums. Don't ask them to change any features, they'll give you ridiculous reasons, and obfuscate they reality of the situation, they might even explode! That's because designing is incomprehensible. Every step is like doing a Rubik's Cube! That is not the reality though. Time committed to Rhino can be a problem . You do need to spend time, and a lot in the beginning to get it. That's true of any CAD program. A lot less time if someone gives you a hand. This model I am designing is taking long because I work on it so little. I had to build a new computer, fix my MG, take a shower. It's going to take 6 months for me to get a wheel done!:twisted: You could do Rhino. I'd help you get started with it if you chose to do it, and there are others who would help you here also. I tried to help out a couple of people but they did not stick with it. Maybe they chose a different path. I would be willing to help anyone else who is willing to try.
