Examples are disclosed that relate to representing a digital project file. One example provides a computing device comprising a logic device and a storage device holding instructions executable to obtain a digital project file comprising a geometric representation of a real physical space, and a user-created annotation associated with a location in the representation. The instructions are further executable to display a representation of the file in a first rendering format, receive a request to display a representation of the file in a second rendering format in which one or more real surfaces of the real physical space are displayed as a virtual rendering, the one or more real surfaces not being displayed as the virtual rendering the first digital rendering format, and, in response to the request, display the representation of the file in the second format.
