Adds a new association between an analytical element and a physical element.

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 24.0.0.0 (24.0.0.0)
Since: 2023

Syntax

C#
public void AddAssociation( ElementId analyticalElementId, ElementId physicalElementId )

Visual Basic
Public Sub AddAssociation ( _ analyticalElementId As ElementId, _ physicalElementId As ElementId _ )

Visual C++
public: void AddAssociation( ElementId^ analyticalElementId, ElementId^ physicalElementId )

Parameters

analyticalElementId: Type: Autodesk.Revit.DB..::..ElementId
Id of the analytical element.

physicalElementId: Type: Autodesk.Revit.DB..::..ElementId
Id of the physical element.

Remarks

The arguments must be ids of an analytical and of a physical element that don't have other associations, otherwise an exception is thrown. Physical element can have one of these categories:

Columns
Curtain Wall Panels
Floors
Generic Models
Mass
Parts
Railings
Ramps
Roofs
Stairs
Structural Columns
Structural Foundation
Structural Framing
Structural Trusses
Structural Beam System
Walls

Analytical element can have one of these categories:

Analytical Member
Analytical Panel

Examples

CopyC#

using (Transaction trans = new Transaction(doc, "AddAssociationBetweenPhysicalAndAnalyticalElements"))
{
   trans.Start();

   ElementId idAnalyticalElem = GetSelectedObject(activeDoc, "Please select analytical element");
   ElementId idPhysicalElem = GetSelectedObject(activeDoc, "Please select physical element");

   //gets the AnalyticalToPhysicalAssociationManager for the current document
   AnalyticalToPhysicalAssociationManager analyticalToPhysicalManager = AnalyticalToPhysicalAssociationManager.GetAnalyticalToPhysicalAssociationManager(doc);
   if (analyticalToPhysicalManager == null)
      return Result.Failed;

   //creates a new association between physical and analytical selected elements
   analyticalToPhysicalManager.AddAssociation(idAnalyticalElem, idPhysicalElem);

   trans.Commit();

CopyVB.NET

Using trans As Transaction = New Transaction(doc, "AddAssociationBetweenPhysicalAndAnalyticalElements")
    trans.Start()
    Dim idAnalyticalElem = GetSelectedObject(activeDoc, "Please select analytical element")
    Dim idPhysicalElem = GetSelectedObject(activeDoc, "Please select physical element")

    'gets the AnalyticalToPhysicalAssociationManager for the current document
    Dim analyticalToPhysicalManager = AnalyticalToPhysicalAssociationManager.GetAnalyticalToPhysicalAssociationManager(doc)
    If analyticalToPhysicalManager Is Nothing Then Return Result.Failed

    'creates a new association between physical and analytical selected elements
    analyticalToPhysicalManager.AddAssociation(idAnalyticalElem, idPhysicalElem)
    trans.Commit()
