Preface

The traversal of components is mainly to facilitate subsequent operations on components, such as property modification of batch components, equation modification, etc. Here are four traversal methods that come with SolidWorks. This article introduces the third traversal method. The first two types of traversal The link method is as follows:

1. Official sample traversal code

In the SolidWorks official API help file, search for "Expand or Collapse FeatureManager Design Tree Nodes Example" to find specific sample code. The sample code contains many filter items. We are only traversing the components here, so we will modify the sample code. , the modified code is as follows. The principle of this traversal is to traverse Node by searching, and then find that the Node type is Component2 type to traverse:

Option Explicit

Sub main()
    Dim swApp As SldWorks.SldWorks
    Dim myModel As SldWorks.ModelDoc2
    Dim featureMgr As SldWorks.FeatureManager
    Dim rootNode As SldWorks.TreeControlItem
    Set swApp = Application.SldWorks
    Set myModel = swApp.ActiveDoc
    Set featureMgr = myModel.FeatureManager
    Set rootNode = featureMgr.GetFeatureTreeRootItem()
    If Not rootNode Is Nothing Then
        traverse_node rootNode
    End If   
End Sub

Sub traverse_node(node As SldWorks.TreeControlItem)
    Dim childNode As SldWorks.TreeControlItem
    Dim componentNode As SldWorks.Component2
    Dim nodeObject As Object
    Dim refConfigName As String
    Set nodeObject = node.Object
    If Not nodeObject Is Nothing Then
        Set componentNode = nodeObject
        If componentNode.GetSuppression <> SwConst.swComponentSuppressionState_e.swComponentSuppressed Then
            Debug.Print componentNode.Name2
        End If        
    End If    
    Set childNode = node.GetFirstChild()
    While Not childNode Is Nothing
        If childNode.ObjectType = SwConst.swTreeControlItemType_e.swFeatureManagerItem_Component Then
            traverse_node childNode
        End If        
        Set childNode = childNode.GetNext
    Wend    
End Sub

2. Python traversal code

To facilitate subsequent comparison, the functions of the Python code and the functions of the VBA code remain the same and will not be deleted. The following is an example of the Python code:

import win32com.client
from swconst import constants

def traverse_node(node):
    nodeObject = node.Object
    if nodeObject is not None:
        if nodeObject.GetSuppression!=constants.swComponentSuppressed:
            print(nodeObject.Name2)
    childNode = node.GetFirstChild
    while childNode is not None:
        if childNode.ObjectType==constants.swFeatureManagerItem_Component:
            traverse_node(childNode)
        childNode = childNode.GetNext

def main():
    sldver=2018
    swApp=win32com.client.Dispatch(f'SldWorks.Application.{
      
      sldver-1992}')
    swApp.CommandInProgress =True
    swApp.Visible =True
    myModel = swApp.ActiveDoc
    featureMgr = myModel.FeatureManager
    rootNode = featureMgr.GetFeatureTreeRootItem2(constants.swFeatMgrPaneBottom)
    traverse_node(rootNode)

if __name__ == '__main__':
    main()
