I was just working on my project and I tried to do an arc rotate and when i put my cursor inside the circle to rotate the view instead of rotating the circle just moves freely as if i was trying to aim at something.  Also when i try to zoom in it only lets my zoom in to a certain extent, also it will not let me pan.  Does anyone have any idea why this is happening and how i can fix it? 

Thank you,

Click and hold the Arc Rotate button - you’ll get a flyout with 3 options.
Top one (grey) is Arc Rotate screen - rotates about the center of the screen
Middle is Arc Rotate Selected - rotates around the selected object(s) which may be off screen!
Bottom is the most useful - Arc Rotate SubObjects. As the name implies it rotates around selected vertices, faces etc. The best bit is that if you have an object selected (rather than sub-objects) it will rotate around that instead. Likewise, if you have no objects selected it works just like the top one.

This is all in the help - Viewport Controls > Viewport Navigation > Perspective and Orthographic Viewport Controls

The Zoom issue is usually caused by the system units being at odds with the size of your objects. Sometimes pressing “Z” will reset it and allow you to carry on zooming, sometimes not.

Thank you very much for your help, just pressing “Z” was all I needed to to.
