Type a name of the camera in the Name field. Click Done. A physical camera model group is created and placed in your model. You are placed in camera view mode, where you are looking through the camera at your subject. A crosshair shows the middle of the camera. Camera properties appear in the lower-left corner of the model. A tab with the camera's name also appears. You can perform several functions on the camera, such as looking through the camera and editing camera properties in camera mode.
Using the Zoom tool physically repositions the camera. I create a scene, set a custom aspect ratio which forces SketchUp to internally use a horizontal FOV, not a vertical and set up a focal length. Then, without moving the camera, I create an Advanced Camera Tools camera in the same place. In Advanced Camera Tools I select a physical camera, e.
This gives me two seemingly identical cameras. However, if I query SketchUp for the focal length two widely different values are returned. Does anyone know if there are additional camera properties not shown in this dialog?
However this value is identical for my two scenes. It seems there is a difference between the two scenes in convertion between focal length and field of view though. Lol, it seems I have a history of finding things myself minutes after I write a post about it and force myself to sort out my thoughts. If I understand everything correctly focal length is in reality a measurement of angle of view, not the physical focal length of the lens.
It certainly adds complexity and makes it harder to understand what is going on, but is there any gain from it? The history of this is lost to me. But yes, the API is weird.
