Adding a camera requires you to attach it to an anchor point to determine their location. This is usually done with a reference frame.
1.SelectProgram➔Add Reference Frameto create a new coordinate system. More information in theGetting started section.
2.Place the frame at the desired camera location, where XYZ coordinates are the camera location, the Z+ axis represents the aim direction, and the Y+ axis represents the down direction.
3.SelectConnect➔Simulate 2D cameraand select the reference frame.
You now have a default camera attached to the anchor point.
