How to YOU use an Interactive Schedule to display lengths of Door Casing?

[Steve Jepson]

I can't think of how to extract length of Casing from the default door and window objects.

I do it in other ways. But it seems like somethign that should be possible to do with the default doors and windows.

That is correct.

The expressions in properties only affect the element they are associated to.

The schedule just tallies those figures from the elements.

The schedules do have a new merge option for each field (merge items must be on to use this).

That can give you a bit more control for how elements are tallied.
