public void SetDesiredReferenceData( ElementId elemId, ModelPath path, PathType pathType, bool shouldLoad )
Public Sub SetDesiredReferenceData ( elemId As ElementId, path As ModelPath, pathType As PathType, shouldLoad As Boolean )
public: void SetDesiredReferenceData( ElementId^ elemId, ModelPath^ path, PathType pathType, bool shouldLoad )
member SetDesiredReferenceData : elemId : ElementId * path : ModelPath * pathType : PathType * shouldLoad : bool -> unit
Parameters
- elemId ElementId
- The id of the element associated with this reference.
- path ModelPath

Exception | Condition |
---|---|
ArgumentException | elemId does not correspond to an ExternalFileReference contained in this TransmissionData. -or- These inputs will not produce a valid ExternalFileReference. |
ArgumentNullException | A non-optional argument was null |
ArgumentOutOfRangeException | A value passed for an enumeration argument is not a member of that enumeration |

There must already be a reference associated with
the given id for this function to be valid. New
references cannot be created in a closed file.
