In this article, we understand “how to” Insert Virtual Assembly in Assembly document from VBA macro.

This is most updated method of inserting Virtual Assembly in an assembly document.

Results We Can Get

Below image shows the result we get.

We Insert Virtual Assembly in simple manners.

There are no extra steps required.

To get the correct result, please follow the steps correctly.

Macro Video

Below 🎬 video shows how to Insert Virtual Assembly from SOLIDWORKS VBA Macros.


Above video is just for visualization and there is no explanation.

I have explained every line in this article.

It is advisable to watch video, since it helps you to better understand the process.

VBA Macro

Below is the VBA macro for Insert Virtual Assembly.

Option Explicit

' Variable for Solidworks Application
Dim swApp As SldWorks.SldWorks

' Variable for Solidworks document
Dim swDoc As SldWorks.ModelDoc2

' Variable for Solidworks Assembly
Dim swAssembly As SldWorks.AssemblyDoc

' Variable for Solidworks Component
Dim swComponent As SldWorks.Component2

' Program to Insert virtual Assembly
Sub main()
  
  ' Set Solidworks Application variable to current application
  Set swApp = Application.SldWorks
  
  ' Set Solidworks document variable to currently opened document
  Set swDoc = swApp.ActiveDoc
  
  ' Check if Solidworks document is opened or not
  If swDoc Is Nothing Then
    MsgBox "Solidworks document is not opened."
    Exit Sub
  End If
  
  ' Set Solidworks Assembly document
  Set swAssembly = swDoc
  
  ' Insert Virtual Assembly
  swAssembly.InsertNewVirtualAssembly swComponent
  
  ' If there are error
  If swComponent Is Nothing Then
    ' Inform user and exit function.
    MsgBox "Failed to add Virtual Assembly."
    Exit Sub
  End If
  
End Sub

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.

prerequisite

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. Insert Virtual Assembly

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.

Option Explicit
' 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 Component
Dim swComponent As SldWorks.Component2
  • Purpose: In above line, we create a variable for Solidworks Component.
  • Variable Name: swComponent
  • Type: SldWorks.Component2.
  • Reference: Please visit 🚀 online SOLIDWORKS API Help.

These all are our global variables.

They are SOLIDWORKS API Objects.

' Program to Insert virtual Assembly
Sub main()

End Sub
  • In above line, we create main Program to Insert virtual 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.

Insert Virtual Assembly

In this section, we Insert Virtual Assembly.

' Insert Virtual Assembly
swAssembly.InsertNewVirtualAssembly swComponent
  • In above code, we Insert Virtual Assembly into assemly.
  • For this, we use InsertNewVirtualAssembly method.
  • This InsertNewVirtualAssembly method is part of swAssembly variable.
  • This method takes 1 parameter.
    • InsertedComponent: New assembly inserted as virtual component.
  • Return Value : This InsertNewVirtualAssembly method return 👉 Error as defined by swInsertNewPartErrorCode_e.

  • In our code, I have used following values:

    Parameter Name Value Used
    InsertedComponent swComponent
  • Reference: For more details please visit 🚀 online SOLIDWORKS API Help.
' If there are error
If swComponent Is Nothing Then
  ' Inform user and exit function.
  MsgBox "Failed to add Virtual Assembly."
  Exit Sub
End If
  • In above code block, we check if we successfully added Virtual Assembly or not.
  • We use 🚀 IF statement for checking.
  • Condition: swComponent Is Nothing
  • When this condition is True,
    • We show and 🚀 message window to user.
    • Message: *Failed to add Virtual Assembly.
    • Then we stop our macro here.

Now we run the macro and after running macro we get a New Virtual Assembly as shown in below image.
