Prerequisite

There are some prerequisites for this article.

• Knowledge of VBA programming language is ❗required.

• We use existing parts in Assembly document.

• Both components are fully constraint as shown in below image.

We will apply checks in this article, so the code we write, should be error free mostly.

Steps To Follow

This VBA macro can be divided into following sections:

1. Create Global Variables
2. Initialize Global Variables
3. Get Feature Data
4. Delete Mate

Every section with each line is explained below.

I also give some links (see icon 🚀) so that you can go through them if there are anything I explained in previous articles.

Create Global Variables

In this section, we create global variables.

' 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.

• 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.

Get Feature Data

In this section, we Get Feature Data.

' 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,
