Hi Frederick,

PS is a 2d application. That's a function of "order"

In the 3d application, Objects are actually hidden behind objects that way. There is no "stack order"

But you can just use the styles to show and hide your objects at whatever layer you want. ctrl clicking to "Top Layer" something. Adding others back in and out as needed..

If you care about the order of the style, it can be moved up and down in the edit styles dialoge...
