Hello ,
Thank you for posting in the community regarding getting your camera view matched from Revit to Twinmotion. At this time there is no way to import Camera's into Twinmotion but we are aware of the need for such a tool, I recommend you make your comments/request on our road-map on any applicable feature or make a new one:

In Twinmotion in order to navigate around you can change from Fly mode to Walk mode then use the Speed shortcuts 1 through 4 then use the navigation shortcuts to move (arrow keys or WASD). Avoid using the mouse if you are navigating inside a building when rooms are small, note that the speed controls affects panning/zooming/walking speeds. You can also find the shortcuts under the help menu in Twinmotion.
Here is a link to our navigation documentation:

Hope this helps.
Kind regards,
