Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.1.0.0 (26.1.0.34)

Syntax

C#

public static IList<GeometryObject> CreateGeometryInstance(
	Document document,
	string definition_id,
	Transform trf
)

Parameters

document  Document

Document to which the created element will be added

definition_id  String

ID of the shape definition that was created earlier and stored via DirectShapeLibrary

trf  Transform

Transform to be applied to the definition

Return Value

IList<GeometryObject>
A collection of GeometryObjects representing a placed instance of the pre-defined shape The caller function takes ownership

Remarks

Use DirectShapeLibrary class to store definitions prior to using them here. How the definitions are stored will determine whether an instance or a copy of the shape will be created. Use the output of this function as input to CreateElement to make the created shape persistent. This is intended to support a definition/instance pattern common in CAD formats - DWG blocks, STEP MAPPED_ITEM, IFC IfcMappedItem.
