I am having a problem with the way my 3D model is displayed when creating layer links and viewports. I am doing a model of a theater with several different design layers for parts of the space (house, balcony, control booth, stage, grid, etc). When viewing and working with my 3D model everything looks good, the control booth sits nicely on the balcony. When I create a layer link of the balcony and the control booth together the booth is suddenly floating 10' or so off the balcony. The same thing seems to be happening when I try to create a viewport with both layers turned on.
I'm not sure what could be causing this. Could it have something to do with the Z or +-Z settings of my layers? I don't quite understand the point of setting the Z base elevation on a layer. For example, I set the Z for a new layer to be 15' and then I created a new wall on that layer. The new wall, however, did not automatically have a bottom Z equal to that layer's base elevation. Am I wrong to assume that new objects would be placed on the layer's base elevation height?
I have added 3 photos to this post with the file manager. They show the 3 different scenarios of viewing; viewing the 2 layers normally using align views, viewing the 2 layers together in a layer link, and viewing the two layers in a common viewport.
Any help would be greatly appreciated!
