PhotoModeler treats each set of photographs and the information needed to produce a 3D model as a Measurement Project or simply "project". PhotoModeler saves the state of your work in a project file and allows you to resume working with saved project files. PhotoModeler does not save each photograph image in the project file, instead the project file refers to your photographs which are stored separately on the hard disk. When your 3D model is complete, PhotoModeler can export many different file formats from your project.
A project can be returned to at any time to refine your measurements or to add detail to your 3D model.
