    Exit Sub
  End If
  
  ' Set Solidworks Assembly document

Prerequisite

There are some prerequisites for this article.

• Knowledge of VBA programming language is ❗required.

• We use existing parts in Assembly document.

• One component is fully constraint and other component is Float as shown in below image.

Steps To Follow

This VBA macro can be divided into following sections:

1. Create global variables
2. Initialize global variables
3. Rename Mate

Every section with each line is explained below.

Create global variables

In this section, we create global variables.

Option Explicit

• Purpose: Above line forces us to define every variable we are going to use.
• Reference: 🚀 SOLIDWORKS Macros - Open new Part document

' Variable for Solidworks application
Dim swApp As SldWorks.SldWorks

• Purpose: In above line, we create a variable for Solidworks application.
• Variable Name: swApp
• Type: SldWorks.SldWorks
• Reference: Please visit 🚀 online SOLIDWORKS API Help .

' Variable for Solidworks document
Dim swDoc As SldWorks.ModelDoc2

• Purpose: In above line, we create a variable for Solidworks document.
• Variable Name: swDoc
• Type: SldWorks.ModelDoc2
• Reference: Please visit 🚀 online SOLIDWORKS API Help .

' Variable for Solidworks Assembly
Dim swAssembly As SldWorks.AssemblyDoc

• Purpose: In above line, we create a variable for Solidworks Assembly.
• Variable Name: swAssembly
• Type: SldWorks.AssemblyDoc
• Reference: Please visit 🚀 online SOLIDWORKS API Help .

' Variable for Solidworks Mate Feature
Dim swMateFeature As SldWorks.Feature

• Purpose: In above line, we create a variable for Solidworks Mate Feature.
• Variable Name: swMateFeature
• Type: SldWorks.Feature.
• Reference: Please visit 🚀 online SOLIDWORKS API Help .

These all are our global variables.

They are SOLIDWORKS API Objects.

' Program to Rename Mate
Sub main()

End Sub

• In above line, we create main Program to Rename Mate in assembly.
• This is a Sub procedure which has name of main.
• This procedure hold all the statements (instructions) we give to computer.
• Reference: Detailed information 🚀 VBA Sub and Function Procedures article of this website.

—### Initialize global variables

In this section, we initialize global variables.

' Set Solidworks Application variable to current application
Set swApp = Application.SldWorks

• In above line, we set value of swApp variable.
• This value is currently opened Solidworks application.

' Set Solidworks document variable to currently opened document
Set swDoc = swApp.ActiveDoc

• In above line, we set value of swDoc variable.
• This value is currently opened part document.

' Check if Solidworks document is opened or not
If swDoc Is Nothing Then
  MsgBox ("Solidworks document is not opened.")
  Exit Sub
End If

• In above code block, we check if we successfully set the value of swDoc variable.
• We use 🚀 IF statement for checking.
• Condition: swDoc Is Nothing
• When this condition is True,
  • We show and 🚀 message window to user.
  • Message: SOLIDWORKS document is not opened.
  • Then we stop our macro here.

' Set Solidworks Assembly document
Set swAssembly = swDoc

• In above line, we set value of swAssembly variable.
• This value is swDoc variable.

Add Rename Mate

In this section, we Rename Mate.

' Get mate feature
Set swMateFeature = swDoc.Extension.GetLastFeatureAdded

• In above line, we set the value of variable swMateFeature by GetLastFeatureAdded method.
• This GetLastFeatureAdded method is part of Extension object.
• This Extension object is then part of swDoc object.
• GetLastFeatureAdded method gives us last added mate.

' Check if successfully Get mate
If swMateFeature Is Nothing Then
  MsgBox "Failed to Get Mate."
  swDoc.ClearSelection2 True
  Exit Sub
End If

• In above code block, we check if we successfully get Last Mate or not.
• We use 🚀 IF statement for checking.
• Condition: swMateFeature Is Nothing
• When this condition is True,
  • We show and 🚀 message window to user.
  • Message: Failed to Get Mate.
  • After that we clear the selection.
  • Then we stop our macro here.

' Select the mate
swMateFeature.Select True

• In above line we select the mate by Select method.
• This Select method take either True or False.
  • True: Appends the feature to the current selection list.
  • False: Replaces the current selection list.

' Start editing mate feature
swDoc.FeatEdit

• In above line we start editing mate feature by FeatEdit method.
• This FeatEdit method puts the current feature into edit mode.

' Variable for mate's new name
Dim newName As String

• Purpose: In above line, we create a variable to store new name.
• Variable Name: newName
• Type: String

' Get mate's new name
newName = InputBox("New Name:", "Edit Mate")

• In above line of code we are doing 2 steps in one line.

  Those 2 steps are explained below.

  • Step 1 - Getting New Name from user.

  Below image shows the message for New Name to the user.

  

  • Step 2 - Assigned input value to newName variable.

' This will handle empty value or cancel case
If Len(newName) = 0 Then
  MsgBox "Empty or no value. Please try again."
  swDoc.ClearSelection2 True
  Exit Sub
End If

• In above code block, we check the length of input value.
• This check will handle case for empty value or cancel operation case.
• We use 🚀 IF statement for checking.
• Condition: Len(newName) = 0
  • Len() is pre-build VBA function which check the length of a object.
  • In above cases, we will get 0 value.
• When this condition is True,
  • We show and 🚀 message window to user.
  • Message: Empty or no value. Please try again.
  • Then we clear all selection and stop our macro here.

' Update mate's name
swMateFeature.Name = newName

• In above code block, we update selected mate’s name.
• For this we set the value Name property of swMateFeature variable.
• Reference: Please visit 🚀 online SOLIDWORKS API Help for more help.

' Clear all selection
swDoc.ClearSelection2 True

• In above line, we clear all selection.
• For this we use ClearSelection2 method which is part of SOLIDWORKS Document variable i.e swDoc variable.

' Rebuild assembly
swDoc.ForceRebuild3 True

• In above line, we Rebuild assembly.
• For this we use ForceRebuild3 method which is part of SOLIDWORKS Document variable i.e swDoc variable.

Now we run the macro and after running macro we get Rename Mate as shown in below image.
