It looks like there is a transform node called 'skp_camera_Last_Saved_SketchUp_View' that shows up in the collada model exported from Sketchup. However, you could also navigate in Inspector and then right click and copy the camera's position and euler values. If you are using vizcave powerwall code directly without vizconnect then set the CaveView position to place the user at a specific location in the scene. See the section on viewpoint movement in the
vizcave documentation for more information.
