user9184: I'm trying to simulate water filling up a closed sphere, but I'm having trouble getting Newton to recognize that my box is empty on the inside but has borders. It only sees my box as a solid object and I am unable to put anything else inside of it.
I've tried removing the fill and playing around with the box's properties but it doesn't seem to be affecting anything. I know it's possible because I've seen a few videos using the technique, but not a single one explaining how to do it.
In short, I want to be able to create a "hollow" box that Newton can see and that I can fill with a bunch of tiny balls.

user11803: instead of shape layer with outline use solid layer with masks to recreate the outline. that seems to work for me..
