SetProjection Method (AnalyticalElementSelector, ElementId, StickElementProjectionZ)

Sets the analytical model projection to a preset value.

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.484.0)
Since: 2015

Syntax

C# 
public void SetProjection(
	AnalyticalElementSelector selector,
	ElementId planeIdY,
	StickElementProjectionZ projectionZ
)
Visual Basic 
Public Sub SetProjection ( _
	selector As AnalyticalElementSelector, _
	planeIdY As ElementId, _
	projectionZ As StickElementProjectionZ _
)
Visual C++ 
public:
void SetProjection(
	AnalyticalElementSelector selector, 
	ElementId^ planeIdY, 
	StickElementProjectionZ projectionZ
)

Parameters

selector
Type: Autodesk.Revit.DB.Structure AnalyticalElementSelector
End of the analytical model.
planeIdY
Type: Autodesk.Revit.DB ElementId
Plane on to which analytical model may be projected in Y direction. Plane identifies a Level, a Grid, or a Ref Plane.
projectionZ
Type: Autodesk.Revit.DB.Structure StickElementProjectionZ
Preset value for Analytical Model Stick projection Z.

Examples

Copy C# 
public void ChangeBeamProjection(FamilyInstance familyInstance)
{
    AnalyticalModelStick ams = familyInstance.GetAnalyticalModel() as AnalyticalModelStick;
    if (ams != null)
    {
         // Change the Z projection for the end of the beam
         StickElementProjectionZ orgEndProj = ams.GetProjectionZ(AnalyticalElementSelector.EndOrTop);
         StickElementProjectionZ newEndProj = StickElementProjectionZ.Bottom;
         using (Transaction tran = new Transaction(familyInstance.Document, "ChangeProjection"))
         {
             tran.Start();
             ams.SetProjection(AnalyticalElementSelector.EndOrTop, ElementId.InvalidElementId, newEndProj);
             tran.Commit();
         }

         TaskDialog.Show("AnalyticalModelStick", "AnalyticalModelStick ID: " + ams.Id + "; \nOriginal ProjectionZ value was: " + orgEndProj + "; \nNew ProjectionZ value: " + newEndProj);
    }
}
Copy VB.NET 
Public Sub ChangeBeamProjection(familyInstance As FamilyInstance)
   Dim ams As AnalyticalModelStick = TryCast(familyInstance.GetAnalyticalModel(), AnalyticalModelStick)
   If ams IsNot Nothing Then
      ' Change the Z projection for the end of the beam
      Dim orgEndProj As StickElementProjectionZ = ams.GetProjectionZ(AnalyticalElementSelector.EndOrTop)
      Dim newEndProj As StickElementProjectionZ = StickElementProjectionZ.Bottom
      Using tran As New Transaction(familyInstance.Document, "ChangeProjection")
         tran.Start()
         ams.SetProjection(AnalyticalElementSelector.EndOrTop, ElementId.InvalidElementId, newEndProj)
         tran.Commit()
      End Using

      TaskDialog.Show("AnalyticalModelStick", "AnalyticalModelStick ID: " + ams.Id.ToString + "; " & vbLf & "Original ProjectionZ value was: " + orgEndProj + "; " & vbLf & "New ProjectionZ value: " + newEndProj)
   End If
