this could be due to navis switching from ortho to perspective when you pick the walk tool...right click on an item in the tree, there should be an option to focus on item...that might help you find your model.
also there could be 'space junk' in you model that is a long way from the geometry that you want to look at...nav could be zooming to extents.
Hello. It’s possible you have to adjust your clipping plane settings:
1.) Open your model
2.) On the Home tab, click “File Options”
3.) Access the “Culling” pane
4.) Set your “Near” clipping Plane to “Fixed” and enter a low number. This is where the model will clip the near plane. Enter “-10” to start
5.) Click “OK”
6.) If you need to adjust the “Far” clipping plane, enter a large number.
You can also try to adjust your Camera Position on the Viewpoint > Camera dropdown.
or the camera view.

If the user is required to use "fixed" settings why is there an "automatic"? I currently generate models every night with clipping planes set to automatic. Some days this works fine, other days I get this problem, but only for some saved views. I then have to instruct users to set a low/high number setting, try it again and it works. If we then reset to automatic, it seems to function ok. looks like a bug in the automatic calculation to me
Automatic is nice for those with low- to mid-quality computers and little computer knowledge, at least with the far clipping plane. In theory the automatic calculation should take care of that without users having to mess around with the settings.
Can anybody/AutoDesk comment on the procedure used for automatically calculating the clipping plane distances? In some cases the near plane is visibly "forward" of the viewpoint, which then needs to be reset as noted. I have never been able to suss out exactly what pushes the near clipping plane to that point, and it would be useful to know.
