Simulation makes image jump forward.

I am wanting to make a complete assembly (or object) rotate around 180 or 360.  Image you are looking at a car on a turntable and it rotates around so you can see all sides as it rotates. If I use the mouse and rotate it by hand it does what I want manually.  But when I want to use simulate to rotate it by setting the object at its starting point at time 0.0, then move the time slider out to a few seconds and rotate the object where I want it to end up... the simulation starts out correct, then it makes the object go "towards" you as if zooming in really close as it rotates then finally it settles back to the correct zoomed view when completing the move.  Why does the object zoom in like this?  Thanks. Is there a way I can just make my object rotate 180 or 360 and stay at the same zoom?

The issue occurs because Fusion 360 uses a camera-based perspective for animations, and when you manually rotate and set keyframes, the camera path can include unintended zooming due to interpolation. To fix this, set your camera to "Perspective with Ortho Faces" or "Orthographic" mode, and ensure the camera view remains fixed throughout the animation. Lock the camera position before animating (right-click the ViewCube and select "Set Current View as Home"), or manually edit the keyframes to maintain consistent zoom levels. This ensures smooth rotation without unwanted zooming.
I think... I hope... TAKE CAUTION WITH ANYTHING I WRITE.

Thanks for the tips, before posting I had already searched for camera on the simulation page.  It is nowhere to be found.  In the design page it is easy to find on the view icon.

Solved:   I was saying Simulation but I am really trying to solve this in Animation, sorry for the wrong term. 

I cannot solve this by rotating manually and then running Play Animation, the object moves very forward and even goes so far forward( Zoomed) you cant see it sometimes.  I solved it by placing the object where I want the animation to start.  Then press the Transform icon at the time which opens up a popup to select an amount to move the object in any direction and also an amount to rotate the object around a certain axis.  This method is perfect and keeps the object centered. They removed the camera perspective from the lower icon view settings, but if you right click on HOME at the top right icon it gives you options to select ortho or perspective.   Thanks
