Incremental measure (delta x,y,z) function in Creo 4
The below mapkeys create a macro for using the incremental measure functionality. If it is something you use often this is worth automating. I have added this to the UI customization available in Creo 4. It works in part mode and assembly mode.
The mapkey "imdi" calls the measure tool and defines a projection reference using a csys of the current model.
I am exploiting the default csys in start models having containing the string "csys_def".
It uses a search function that selects a csys whose name contains the following string "*csys_def". If your start part(s) use a name for the default csys that is different you will need to modify the ".fcsx" mapkey accordingly.
