Something wrong with 3D

[CIA20]

Please help !

By chance I have pressed some keys and my 3D looks wierd 

as if something is cutting it off. 

I need to desactivate it but can't find where. Would like to know also what shortcut did I presss to activate this function.

Thank you for your help.

Hi,

From what I saw, it can either be a clipping plane issue or a OpenGL issue.

Maybe you can take a look here

Possible solutions:
- switch to axonometric and back to perspective, see if the issue persists?
- rebuild the file (it may become corrupted)
- check the 3D style option settings - maybe it can help? 
edit:
- it also may occur if your model is placed too far away from the origin - maybe check that as well

This might also be an object placed far away from the project origin.

Try to go to the floorplans zoom to fit with all the layers turned on to check.

Given the artifacts, I would assume it is a Project Origin issue.

Problem solved ! 

The issue occurred after I pressed some keys on my keyboard, causing two walls to intersect at an infinite point. Removing that solved my 3d.
