FamilySymbol Class

An element that represents a single type with a Family.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 2015.0.0.0 (2015.0.0.0)

Syntax

C# 
public class FamilySymbol : InsertableObject
Visual Basic 
Public Class FamilySymbol _
	Inherits InsertableObject
Visual C++ 
public ref class FamilySymbol : public InsertableObject

Remarks

Custom families within the Revit API represented by three objects - Family, FamilySymbol and FamilyInstance . Each object plays a significant part in the structure of families. The Family element represents the entire family that consists of a collection of types, such as an 'I Beam'. You can think of that object as representing the entire family file. The Family object contains a number of FamilySymbol elements. The FamilySymbol object represents a specific set of family settings within that Family and represents what is known in the Revit user interface as a Type, such as 'W14x32'. The FamilyInstance object represents an actual instance of that type placed the Autodesk Revit project. For example the FamilyInstance would be a single instance of a W14x32 column within the project.

Examples

Copy C# 
public void GetInfo_FamilySymbol(FamilySymbol familySymbol)
{
    string message;
    // Get FamilySymbol family name
    message = "Family name is : " + familySymbol.Family.Name;

    // Get FamilySymbol material
    message += "\nFamilySymbol materials are :";
    foreach (ElementId matid in familySymbol.GetMaterialIds(true))
    {
       Material material = familySymbol.Document.GetElement(matid) as Material;
       if (null != material)
       {
          message += "\n" + material.Name;
       }
    }

    TaskDialog.Show("Revit",message);
}
Copy VB.NET 
Public Sub GetInfo_FamilySymbol(familySymbol As FamilySymbol)
    Dim message As String
    ' Get FamilySymbol family name
    message = "Family name is : " & Convert.ToString(familySymbol.Family.Name)

    ' Get FamilySymbol material
    message += vbLf & "FamilySymbol materials are :"
    For Each matid As ElementId In familySymbol.GetMaterialIds(True)
        Dim material As Material = TryCast(familySymbol.Document.GetElement(matid), Material)
        If material IsNot Nothing Then
            message += vbLf + material.Name
        End If
    Next

    TaskDialog.Show("Revit", message)
