Still, getting back to parity +takes a lot of time and it's not quite there. It does simplify MSC HDF5 +integration, so once I've added methods for updating more complicated objects +(e.g., PBARL, PCOMP, RBE3), HDF5 will be next.

They take some getting used to but + you can make plots of shear, moment, and torque down an axis. + - A recent files history to speed up model loading and a whole bunch of other bug fixes.
