Marie, thank you! This is very helpful.
The next thing I need to do it try to duplicate what you have created here with the mates & the physical simulation.
I do have one question though with this specific representation.
Why does the ball move at a constant rate?
Shouldn't it eventually come to rest at the bottom of a bowl with actual gravity represented?
Also, thinking about this year's challenge specifically, would there be a possible way to not add mates other than a possible collision detection, & make a group of balls fall in the bowl from a height above it & see how they would naturally come to rest - or at least an estimate of how many would fit in there without overflowing?
I tend to ask a lot from this software, & thus "hack it" (so to speak) to make it do what I want, or be as close to possible most times.
(ie: My group in class made a Geneva Wheel "kinda" work in 2001 in Solidworks before the Advanced Mates came into the software. It was quite interesting to say the least how it was supposed to work, & how it actually worked.

)
Also, as a side note, this is not an urgent request of information, so if other pressing issues come up, feel free to take care of those first.
This is just for my own personal reference, & the need to want to take my knowledge of this part of the software to a new limit.
Thank you again for all your help!
