Below 🎬 video shows how to Show Component 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 Show Component.

                        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 Show Selected Component
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
  
  ' Variable for List of elements
  Dim vArray As Variant
  
  ' Get Components list in opened assembly
  vArray = swAssembly.GetComponents(True)
  
  ' Variable for component
  Dim component As Variant
  
  ' Loop Components List
  For Each component In vArray
  
    ' Set Solidworks Component variable
    Set swComponent = component
    
    ' If current component is hidden
    If swComponent.IsHidden(False) Then
      
      ' Select the component
      swComponent.Select False
      
      ' Show selected component
      swDoc.ShowComponent2
    End If
    
  Next component
  
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.
We select the part which we want to Show.

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:

Create Global Variables
Initialize Global Variables
Show Component

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

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

                        ' 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 Show Selected Component
Sub main()

End Sub

In above line, we create Program to Show Selected Component.
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.

Show Component

In this section, we perform Show Component action.

                        ' Variable for List of elements
Dim vArray As Variant

Purpose: In above line, we create a variable for List of elements.
Variable Name: vArray
Type: Variant

                        ' Get Components list in opened assembly
vArray = swAssembly.GetComponents(True)

In above line, we set the value of vArray variable.
We set value by GetComponents method of swAssembly variable.

                        ' Variable for component
Dim component As Variant

In above line, we create component variable for looping.
Variable Name: component
Type: Variant

                        ' Loop Components List
For Each component In vArray
  
Next

In above line, we create a For Each loop.
In this loop, component variable loops every item in vArray.

                        ' Set Solidworks Component variable
Set swComponent = component

In above line, we set value of swComponent variable.
This value is current value of array vArray.
Current value is represented by component variable.

                        ' If current component is hidden
If swComponent.IsHidden(False) Then
  
End If

In above code block, we check if current component is hidden.
We use 🚀 IF statement for checking.
Condition: swComponent.IsHidden(False)

                        ' Select the component
swComponent.Select False

In above line, we select the component.
We use Select method of swComponent variable.

                        ' Show selected component
swDoc.ShowComponent2

In above line, we Show selected component.
We use ShowComponent2 method of swDoc variable.
This method return nothing.

Now we run the macro and after running macro we show selected component as shown in below image.

This is it !!!
