Pipe tag to determine height difference between two different pipes

[jiri_polacek]

Hi, I need help to see if it is possible to code a pipe tag, which would return a height difference between two pipes. 

Thank you,

When you say 'code', do you mean programming using the Revit API?

I am pretty certain that what you ask for is possible manually using the normal end user interface.

It would help to determine the exact manual steps to achieve what you need first.

Then, it will probably be pretty straightforward to reproduce the same required functionality programmatically using the API.

That corresponds to the standard approach to research how to address a Revit API programming task:
