rb1957,
I like the non manifold add function, which has me wondering much less about whether or not my adjacent surfaces will be actually connected.
I also think the washer/offset curves command is awesome and is really useful for improving meshes around openings easily.
But the coolest, for my money, is the meshing toolbar, with on the fly mesh regens, by just choosing curves after having spec'd the number of nodes on those curves.
Until this version, I hardly ever approached surface meshing by selecting individual curves and specifying qty's of elements/nodes, and then blindly remeshing.
It simply was not as intuitive as it is now.
I am really impressed, given that I commonly model plate structures with stiffeners (stressed skin).
I suppose some of the features were technically already there, but now, they're packaged in a way that is conducive to practically using them.
