Copy & Paste

Copies one parameter's value into another on the same element. Filling a shared parameter from a built-in one, carrying a type value down to instances, putting the project number on every sheet.

Steps

1. Categories — which elements: tick the categories, and add a filter if only some of them should take part.
2. Copy from (any parameter) — the source parameter.
3. Paste into — the target parameter.

Either can be an instance or a type parameter, in any combination. Values are converted between storage types: a length goes into another length unchanged; anything else is passed as the text the project shows.

Example

More settings

• From Project Information reads the source from Project Information instead of the element — the same value lands on every element. Project Information has no type, so the Copy from tag is locked to Instance while it is on.
• Use regex takes only part of the source. Regex pattern W-(\d+) turns W-123A into 123: with a group in brackets the group is copied, without one the whole match. If no match: Keep original copies the whole source value, Clear value empties the target, Custom value writes your text.

Works with

• Parameters: any parameter of the element — shared, project, family or built-in — typed by name, or a built-in one picked from the list; see Which parameters an operation can use.
• Smart tags: in the Custom value written when the regex does not match — see Smart tags.
• Only if empty: tick it for this operation in the Executor's list before a run, and it writes only where the target is still empty.
• Preview: type sample values and see what the operation writes, before Revit — see Preview and Example.
• Filter, Active view, Selection: like every operation — see the filter and Whole model, Active view, Selection.
