Selecting a Reference#

The Select Reference command establishes the reference plane that lineset distances are measured from and links linesets to it. Running it is the first step in setting up a project for distance tracking and synchronization.

What the command does#

  1. Optionally reads any linesets you pre-selected before running the command.
  2. Prompts you to pick a reference plane in the model.
  3. Associates linesets with that plane by writing the plane's name into each lineset's Reference Plane Name parameter.
  4. Records the measured distance of each associated lineset into its distance parameter.
  5. Remembers the chosen plane as the current locator for the session.

Two ways to run it#

Associate specific linesets#

Select one or more linesets first, then run Select Reference and pick the plane. The linesets you selected are associated with the plane and have their Use Dynamic Scheduling parameter turned on automatically.

Use this approach when you want precise control over which linesets belong to a plane — for example, when a venue has more than one datum.

Associate everything nearby#

Run Select Reference with nothing selected, then pick the plane. Every lineset within 50 feet of the plane that does not already have a reference is associated automatically.

Use this approach to set up a whole rigging system against a single plaster line in one step.

Steps#

  1. (Optional) Select the linesets you want to associate.
  2. On the Linesets panel, click Select Reference.
  3. Click the reference plane in the model. A confirmation appears once the association is stored.

Tip

Name your reference plane clearly before associating linesets — the link is stored by name. See Reference Planes.

Note

A reference plane stays the current locator until you select a different one or close Revit. The Sync Schedule and Update Locations commands act against the current locator.
