Preparing Linesets

Before any command will act on your rigging, the model needs two things: family instances the add-in recognizes as linesets, and a reference plane to measure them from.

1. Confirm your rigging families are linesets

A family instance is treated as a lineset only when both of these are true:

• It is in the Specialty Equipment category.
• Its type has the "Is Lineset" shared parameter set to Yes.

Place at least one rigging family instance in your model — for example, a single batten over the stage. If you are using Performance BIM rigging families, the required parameters are already present. If you are using your own library, confirm the parameters described in Linesets are carried by the family.

2. Add a reference plane at the stage

Draw a Revit reference plane where you want lineset distances measured from — typically the stage plaster line — and give it a clear, unique name such as Plaster Line. Distances will be measured perpendicular to this plane.

3. Open a model view

The lineset commands run in a project (model) document. A plan view of the stage is the most convenient place to work, because you can see the linesets and the reference plane together.

When your model has at least one lineset and a named reference plane, continue to Setting the Reference.
