It shows the progress of activities on the drawing in different colors for Completed, Progressing, Pending and Delayed activities / objects. It also shows the activity listing on the drawing with progress bars. Once a project has been set on Progress Drawings software, it is a matter of few seconds to generate new progress drawings for latest updates of your Primavera project updated schedule. It has its own online graphical viewer, by which you can go to any desired date to know how the project planned or what was the progress.
