Mesh not visible when passing in front of a model.

I'm a beginner. I have done something to my model that isolates it. New added meshes in the viewport disappear when in front of the model.  Checked layers. All on same layer and I can see the new mesh until it passes in front of the older work (the model). 

BTW: LOVE this course! So helpful!



No such problem with my trigger. The cube does not disappear when it passes in front.


Thanks for any ideas how I got my model in such a state.

    Hey mmarilyn-berry , so glad you're finding it useful! The one thing that comes to mind here is x-ray, which can be enabled or disabled in the Object properties under Display. If that's on for the objects that keep overlapping the new object for some reason, turn it off and you'll be good to go.
