Our current work process is to receive PCF's from the 3D design model, translate, analysis and suggest changes if needed to the design team, then repeat as the 3D model changes. Currently the only way to see design changes is to visually search the model or compare text data. This tool would allow users to open the current translated PCF, analysis the model then compare the model / results against a saved earlier version and report back the differences both visual and nonvisual (attribute changes).
