Pointools stores the current project settings, configurations and tool states in project files. This includes all cameras and references to all loaded objects.
The project file format was re-written for release 1.6 to improve stability and extensibility of the format. As a result project file versions prior to 1.6 are no longer supported.
Project files have the extension .ptl.
For large object types, a reference in the form of a filepath to the object file is stored rather than the data itself. This allows you to build many projects around the same set of data without replicating the object data. If Pointools can't find a referenced object on loading a project, you will be prompted to locate the file manually.
To set project properties go to the File | Properties menu item. The dialog box shown below appears. Fill out the details and click OK to accept.
