disappearing level markers

[thomasf]

I am working on some stair sections and some of my level markers are not showing up. In 3 of my views I was able to turn the crop regions off and drag the missing markers into the view, however this is not working with the 4th one. I can drag it inot the view and as soon as I turn the crop regions back on it disappears.

Anybody have any ideas?

In that 4th one, the 3D extents must be entirely outside of the extents of that view's crop region. Turn off the crop region, find the levels, and when you select one you should see open circles indicating the 3D extents of those levels. You should be able to drag the extents across so that they appear in the view after turning the crop region back on.

If that doesn't work, then the 3D level extents may not be within the far clip boundary of the view. To fix that, first check how deep that particular view extends by clicking on the section or elevation mark in plan view. Then go to a view perpendicular to that 4th view, and you'll probably find that the 3D extents of the levels are not within the far clip boundary of the view.
