A project file allows one to save all the files generated by MDT during the course of a project. Apart from being useful for users, this is also useful for the MDT program itself, as there are commands that take this information into account to set default options to specify files, detect files that should be regenerated, etc.
In addition, with MDT8 if we work on an active project, we will have the possibility of automatically updating the drawing of the longitudinal profiles and the cross sections based on any change made either to the alignment or surface of the related drawing.
