Topic Title

I'm putting a building of units together usinc XREFs of the units. When I place an XCLIP on the unit (using a Polyline Entity to define the clip boundries) and tell it to "Ignore Z", everything looks fine in Plan View. Then when I flip it up into Isometric View, anything that is 3D does not clip out. They are all still there overlapping each other. The same thing happens when I use the Object Viewer to see the rendered model.

Is there a setting I have missed somewhere to fix this?

As of right now Xclips only work properly in ortho view. This is on the to-do list.
