Traversing the components tree using SOLIDWORKS API

This example demonstrates how to traverse components tree in the assembly using SOLIDWORKS API and output the result using the specified indentation symbol.

Dim swApp As SldWorks.SldWorks
Dim swModel As SldWorks.ModelDoc2

Const INDENT_SYMBOL As String = "    "

Sub main()

    Set swApp = Application.SldWorks
    
    Set swModel = swApp.ActiveDoc
    
    If Not swModel Is Nothing Then

        Dim swRootComp As SldWorks.Component2

        Set swRootComp = swModel.ConfigurationManager.ActiveConfiguration.GetRootComponent
    
        TraverseComponent swRootComp, ""

    Else

        MsgBox "Please open assembly"

    End If
    
End Sub

Sub TraverseComponent(comp As SldWorks.Component2, indent As String)
    
    Dim vChildComps As Variant
    
    vChildComps = comp.GetChildren
    
    Dim i As Integer
    
    For i = 0 To UBound(vChildComps)
    
        Dim swChildComp As SldWorks.Component2
        Set swChildComp = vChildComps(i)
            
        Debug.Print indent & swChildComp.Name2 & " (" & swChildComp.GetPathName() & ")"
        
        TraverseComponent swChildComp, indent & INDENT_SYMBOL
        
    Next
    
End Sub
