Select All Instances

writes to model Public API · not yet exposed

Coming soon

Before you run this

Active document must be open. Either familyName parameter must be provided, or user must have a FamilyInstance selected.

After it runs

Revit selection is replaced with ALL instances of the matching family/type in the entire model. Returns JSON with totalSelected and breakdown by level and type.

When to use this

User selects one socket and says "select all of these in the model".
User wants to count all instances of a specific family type across all levels.
User wants to bulk-edit all instances of a specific family.

Don't use this when

Selecting in current view only (use SelectByFamilyNameCommand with scope=view). Category-wide selection (use SelectByCategoryCommand). Filtering an existing selection (use FilterSelectionCommand).

Inputs

Name	Kind	Type	Required	Default	Description
`familyName`	config	`string`	no	—	Family name to match (or leave empty to use current selection)
`typeName`	config	`string`	no	—	Optional type name for exact match

Returns

Name	Type	Description
`Selection`	`ElementId[]`	All matching instance IDs
`Summary`	`JSON`	Count and breakdown by level

Decision flow

check: parameters.familyName → use directly
check: selection has FamilyInstance → derive family/type from it
check: parameters.typeName → if set, match type too (not just family)
default: match family name only (all types)
