Hi All
I am new user and learning sketchup,
I have an issue that whatever model I will create it will have issue that during zoom in the picture or model blur and can’t view it properly. (I guess its flipping issue)
I have tried all the option Field view from 0 to 120, size of the model, remove all the unnecessary items, center the model but couldn’t resolve the issue. I have attached the sample.
Appreciate for the advise.

This is called Z-Fighting and occurs when two faces try to occupy the same place. Basically remove the face that is causing the issue, or move them apart.

Yes it was the issue.
