Kevin, CSI technical support is amongst the worst there is. Inspite of the "exhorbitant" amounts of money you spend on tech support, hardly have I ever gotten to speak with a rep the first time. They always have to call back (and this means usually 2-3 days later if I am lucky). As with the meshing, I have always found it easier to draw meshing lines using null lines to make sure my connectivity is correct. Sometimes when a column in not at grid intersections, it can give funny results for that beam/slab - column moment because of it not being meshed. Meshing is wonderful if the columns are all on grid intersections (like in the examples), but its the real world. I always draw meshing lines and connect slab edges, columns etc. and turn off my grid lines during meshing. This has helped so far. I have never tried RISA 3d, so I cannot offer an opinion.
