OdDbBlockReference Methods

	Name	Description
	appendAttribute	Appends the specified OdDbAttribute to the attribute list of this block reference.
	attributeIterator	Returns an AttributeIterator for this block reference.
	blockTableRecord	Returns the Object ID of the block table record associated with this OdDbBlockReference (DXF 2).
	blockTransform	Returns the transformation matrix mapping a point in the MCS to the WCS.
	copyFrom	Copies the contents of the specified object into this object.
	dwgInFields	Reads the .dwg file data of this object.
	dwgOutFields	Writes the .dwg file data of this object.
	dxfIn	Reads the DXF format data of this object from the specified filer.
	dxfInFields	Reads the DXF data of this object.
	dxfInFields_R12	Reads the DXF R12 format data of this object.
	dxfOut	Writes the DXF format data of this object to the specified filer.
	dxfOutFields	Reads the DXF data of this object.
	dxfOutFields_R12	Writes the DXF data of this object.
	explodeGeometry	Explodes this entity into a set of simpler entities.
	explodeToBlock	Explodes this entity into a set of simpler entities, and adds them to the specified block table record.
	explodeToOwnerSpace	Explodes the current object and appends resulting entities to the block table record which owns the current OdDbBlockReference object that calls this method.
	geomExtentsBestFit	This method gets copies of all entities in the referenced block table record, applies parentXform to them and after this calculates extents on the resulting object collection.
	getPlane	Returns the plane that contains this entity.
	isPlanar	Returns true if and only if there is a plane that contains the entity. In another case this method returns false.
	normal	Returns the WCS normal to the plane of this entity (DXF 210).
	openAttribute	Opens an attribute owned by this block reference.
	openSequenceEnd	Opens the OdDbSequenceEnd entity for this block reference.
	position	Returns the insertion point of this block reference (WCS equivalent of DXF 10).
	rotation	Returns the rotation angle applied to this block reference (DXF 50).
	scaleFactors	Returns the scale factors applied to this block reference (DXF 41, 42, 43).
	setBlockTableRecord	Sets the Object ID of the block table record associated with this OdDbBlockReference (DXF 2).
	setBlockTransform	Sets the transformation matrix mapping a point in the MCS to the WCS.
	setNormal	Sets the WCS normal to the plane of this entity (DXF 210).
	setPosition	Sets the insertion point of this block reference (WCS equivalent of DXF 10).
	setRotation	Sets the rotation angle to be applied to this block reference, in radians (DXF 50).
	setScaleFactors	Sets the scale factors to be applied to this block reference (DXF 41, 42, 43).
	subClose	Called as the first operation as this object is being closed, for database-resident objects only.
	subExplode	Replace OdRxObjectPtrArray details Explodes this entity into a set of simpler entities.
	subGetClassID	Overridables.
	subGetCompoundObjectTransform	Returns the transformation matrix of compound object.
	subGetGeomExtents	Returns the geometry extents.
	subGetGsMarkersAtSubentPath	This is subGetGsMarkersAtSubentPath, a member of class OdDbBlockReference.
	subGetSubentPathsAtGsMarker	This is subGetSubentPathsAtGsMarker, a member of class OdDbBlockReference.
	subGetTransformedCopy	This is subGetTransformedCopy, a member of class OdDbBlockReference.
	subHandOverTo	Called as the first operation of the handOverTo function.
	subSetAttributes	Sets the values of this object's subentity traits, and returns with the calling object's subentity traits.
	subTransformBy	Applies the specified 3D transformation matrix to this entity.
	subViewportDraw	Computes the entity to produce the right appearance given each viewport's possibly different viewpoint of the entity.Draws an entity in layout viewports.
	subWorldDraw	Returns true if the entity has no view-dependent graphics. In another case returns false.
	treatAsOdDbBlockRefForExplode	Determines how the entity should be exploded.
