Global parameter Sheet number filter

[mbakVB5E9]

I would like to know if anyone knows how to add a global parameter to a project that reads the sheet number that is in the Identity Data in the sheet properties.

Example: ET-00-00 (Disciplin-Topic-Floor level)

Now after it reads that data it has to remove the first 3 characters in it's own text.

In this example you would have:

Sheet Number: ET-00-00

Sheet Topic: 00-00 (because in this it would have removed the [ET-])

Does anyone know how to apply such a parameter to my sheets?

Formulas with string manipulation are not known in Revit.

Solution would be to assemble your parameters differently or use Dynamo.

Dynamo can read parameters manipulate the values and then push them back into a (new) parameter

Thanks for the Reply.

Shame that this cannot be done within Revit itself.
