thanks for this. it's very helpful. i've been watching the progress of each program, however, it's hard to tell the true differences without actually getting deeply involved with each program. you're modelling skills are amazing. you were doing things in MoI I didn't even know where possible. My modelling skills are very basic. For a 1.0 release, and the time frame he did it in, Plasticity is impressive. It will help motivate the entire cad world, which has been very slow to progress and often just flat out ignores user requests. Rhino hasn't addressed anything significant that causes me, and many others, problems. I never even had to report any of the problems, because there are 1000s of forum posts about them already, lol. Rhino keeps tacking on stuff I will never use. Plus, their pricing for what I need, just doesn't jive. There really isn't anything I love out there. Each program has pros and cons. Your solution of using multiple tools, is the necessary coarse of action for the foreseeable future.

Rhino has the worst kernel but all the features i need. however, they just don't work good and i have to try over and over to get a half decent result. if they had a good kernel and sold varying levels of features, it would be great. moi is close to what i need but the step export killed it for me. trying to switch from rhino to moi was also much more difficult than i anticipated, as all the commands i use in rhino function completely differently in moi. i'm not sure plasticity has what i would need or ever will. i love the filleting. so i have thought about adding that just so i can make good fillets. something nearly impossible in rhino. the n-sided patching would also come in very handy.

i do hope any given program won't put the other out of business though and somehow everyone can thrive and progress over time. it will be interesting to see what happens. i don't have much hope for rhino, given there development history. moi has impressed me with their dev, community, etc... i just sadly didn't have the experience that most people on the forum have. so i'm still stuck with crappy rhino 5. they never gave me a reason to go to 6 or 7 and 8 is looking pretty bad for me as well. good thing i've been retired for a long time. at this point, it really doesn't matter. the dev time was way to slow, lol. i aged out before cad progressed enough. i was around before rhino 1.0, lol, sigh.
