Lost my view in perspective mode how do I reset the view

How do I reset the view in perspective mode because I don’t know where I am

Hello - try SetView World Perspective


Look at the coordinate read out in the corner.
They are HUGE numbers.
One of the 2 points is your model, and the other is something way off in outer space.

I would Window select around on of the points. It is selects lots of objects, that’s your model.
If it selects just one thing, that’s the likely problem.
Zoom in on it (Zoom Selected) to see what it is.
Delete it if it’s not needed.
Then Zoom Extents will get you back to your model.
