Hello @raja.r This could be due to the loss of precision of the numerical values of the camera attributes in certain models - as in the case of reaching extreme zoom levels. When navigating inside a building, our recommendation is to use the [walk operator](https://docs.techsoft3d.com/communicator/latest/api_ref/viewing/classes/Communicator.Operator.CameraWalkOperator.html#Communicator.Operator.CameraWalkOperator) which is better suited for BIM applications: ![walk_operator](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/d/d247e9a62b0c075d4dc3cbccdd5e6022ccdef10b.png) Thanks, Tino
