>with MoI I wanted to do some new things that just were not being done by any existing CAD program.<

Well, you've already done that and it's still in beta and works like a champ. I think the careful planning and your intention to make it powerful but simple to use has paid off because although some of the tools have needed tweaking as you bring them in, it's had relatively few bugs compared to a lot of other new programs and for that matter, some established programs when they've introduced updates..

Here's the thing I was talking about...
I'd like to place a cylinder ( w/ filleted top ) in the correct position and angle of orientation, while working in the 3d viewport with C-lines. I can make some scaffolding from curves to extrude the cylinder in the right orientation or do it by rotating the entire ring in the front viewport so that the extrude of the cylinder is straight north and south.

Thanks,
