Hello Is there an easy method of tracing which variables/functions are called up/used when referencing a separate mathcad file? Ex: I write and define multiple functions and constants in File 01. File 01 is large and contains many constants and functions. In file 02, I reference File 01, but only use some of the constants/functions. Can I trace which constants/functions are being used from File01 in File02? I know I can delete the reference from File02 and use the trace error function, but this is very tedious for larger files. Thanks for the help
