Revit 2025 API
Mechanical |
Connects a pair of placeholders that can intersect in an Elbow connection.
Namespace: Autodesk.Revit.DB.Mechanical
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax
public static bool ConnectDuctPlaceholdersAtElbow( Document document, Connector connector1, Connector connector2 )
Public Shared Function ConnectDuctPlaceholdersAtElbow ( document As Document, connector1 As Connector, connector2 As Connector ) As Boolean
public: static bool ConnectDuctPlaceholdersAtElbow( Document^ document, Connector^ connector1, Connector^ connector2 )
static member ConnectDuctPlaceholdersAtElbow : document : Document * connector1 : Connector * connector2 : Connector -> bool
Parameters
- document Document
- The document.
- connector1 Connector
- The end connector of the first placeholder.
- connector2 Connector
- The end connector of the second placeholder.
Return Value
BooleanTrue if connection succeeds, false otherwise.

Exception | Condition |
---|---|
ArgumentException | The owner of connector is not duct placeholder. -or- The owners of connectors belong to different types of system. |
ArgumentNullException | A non-optional argument was null |

The placeholders may have a physical intersection but this is not required.
If they are not intersecting the connectors must be coplanar and able to be moved to
intersect each other.
If connection fails, the placeholders cannot be physically connected.
