What is happening?

when I zoom near some geometry the camera looks weird?
please somebody help me

My guess is clipping. There is much about it in the forum if you search.
Also are you working in Parallel Projection? Working in Perspective lessens the chances of encountering it.

And my guess is model extents. How far is the model from the origin? Can you post the model?

Hi there!
I had the same problem while importing and ifc far from the origine (as said Anssi… Hi Annsi!)… Is it your case?
