Problem with Zoom Fit

[Anonymous]

I have turned on all the layers I can and have even used the "light bulb" to see if there is anything that got modeled/drawn and placed a ways off and I don't see anything. My problem is my orbit center changed in the course of working on the project and now when in 3D, it's obviously centering itself based on the extent of the model. I know how to change the center of the orbit, but I can't seem to figure out why my model is zoomed out so far. It has to be something I drew/modeled that isn't showing up but is attached to the site level or something...I just can't figure it out.

Model is built around +1300'. It's as if something is on the site layer (+0')...I just don't see anything.

How do I test this? It could also be a family I've brought in that's somehow creating this problem, but is there an easy way to check this?

Thank you ahead of time...

I've seen this kind of thing occur a couple of times and it has always been the fault of Linked Model or DWG file. I would test be creating a separate copy of the Project (or Detach from Central for a Workshared Project) and then detaching the links.

I would go to a 3d view, Zoom to Fit, then use crossing selection windows around the edges of the view to see if anything gets selected.

I figured it out. It was one of the hanging fixture families I inserted. I didn't find anything in the fixture family, but I deleted them and it was fine. I re-inserted it and everything seemed fine. Weird, but it's working so it's good.

Thank you for your responses.
