Systems and methods of maintaining a focal point of a camera in a 3D environment of a 2D graphical user interface of an authoring application includes displaying a surface upon which one or more content items can be placed and a camera centrally positioned relative to the surface. Further, responsive to an indication to add a content, determining a first elevation of the camera, determining an angle of view of the camera at the first elevation and elevating the camera to a second elevation that is greater than the first elevation of the camera while maintaining a perceived angle of view of the camera. Systems and methods for translating a 3D object include preventing translation of the 3D object in one of three dimensions of the three-dimensional environment while enabling simultaneous translation of the 3D object in the two remaining dimensions of the three dimensions of the 3D environment.
