Good day Bilal,
My plan was to use the parser to allow the user to override the SPEC value in the iso sheet without changing the pipeline spec. The the initial value of the SPEC property is set by the pipeline specification.
I have found without the parser expression, even though the Property Display Status is set to Show:Editable, the specification value is not editable.
My understanding of the parser expression can be used to check the user's input to ensure a legitimate value was entered. This is how I was planning to use the parser in this case.
With the PSDS system we are upgrading from, we would generate isometrics and then manually enter the title block each time. With OPM and OPIM I am trying to get all the information into the model or onto the iso sheets so the draftspeople only enter it once and then if they need to regenerate the isometrics they are not manually entering the data over and over again. Thisis what I meant by the statement "This way moving forward when you generate the iso sheet you do not manually have to change the drawing each time"
Hope this clarifies things.
Ken
