Yes, there are definitely some eccentricities with Rhino, like FilletEdge, but those are things our people learn early in the process. We take advantage of the training material provided by Mcneel with new employees, for example, the “Advanced Filleting” tutorials.
There are only a few reasons that FilletEdge fails, so you model proactively to avoid these pitfalls. Of course, FilletSrf can always save the day when FilletEdge fails to work.
I remember when I first learnt Solidworks in 2006, and I wanted to add a 3mm fillet. It wouldn’t work, and I got a note popping up that said something like “try a different size”, Was that helpful? No, it was annoying. I needed a 3mm fillet, so back to Rhino I went and used FilletSrf to get the results I needed.
I can say that our people that learn both Rhino and Solidworks do comment how much easier Rhino is to learn and to be productive with.
