What Language Is SolidWorks Macro?

SolidWorks is a powerful computer-aided design (CAD) software widely used in the engineering and manufacturing industries. One of its key features is the ability to automate repetitive tasks and create custom functionality through macros.

A macro is a piece of code that can be executed within SolidWorks to perform a specific task or series of tasks.

The Language Behind SolidWorks Macros

To create macros in SolidWorks, you need to use a programming language called VBA (Visual Basic for Applications). VBA is an event-driven programming language developed by Microsoft and is widely used for automation purposes across various applications, including SolidWorks.

With VBA, you can access and manipulate various elements within the SolidWorks environment, such as parts, assemblies, drawings, dimensions, and features. This allows you to automate tasks like creating new designs, modifying existing models, extracting data from drawings, and much more.

Why Use VBA for SolidWorks Macros?

VBA offers several advantages when it comes to creating macros for SolidWorks. Let’s explore some of these benefits:

  • Simplicity: VBA has a relatively easy-to-learn syntax compared to other programming languages. Its simplicity makes it accessible even for beginners.
  • Integration: Since VBA is integrated into the SolidWorks environment, it provides seamless access to the application’s object model.

    This means you can directly interact with various elements within your design.

  • Automation: By using VBA macros, you can automate repetitive tasks that would otherwise take up significant time and effort.
  • Customization: VBA allows you to create custom add-ins and tools tailored specifically to your workflow, enhancing your productivity and efficiency.
  • Community Support: VBA has a large and active community of SolidWorks users who share their knowledge, code samples, and solutions. This makes it easier to find help and resources when needed.

Getting Started with SolidWorks Macros

To start creating macros in SolidWorks, you’ll need to enable the macro recording feature. Once enabled, you can perform a series of actions within the software while SolidWorks records the corresponding VBA code.

This recorded code can then be modified or enhanced to suit your specific needs.

To access the VBA editor in SolidWorks, go to Tools -> Macro -> Edit. This opens the VBA editor window where you can write, modify, or debug your macros.

A Sample SolidWorks Macro

Let’s take a look at a simple example of a SolidWorks macro written in VBA. This macro would create a new part document and add a sketch with a circle. 


Sub CreatePartWithCircle()
    Dim swApp As SldWorks.SldWorks
    Dim swModel As ModelDoc2
    Dim swPart As PartDoc
    Dim swSketchMgr As SketchManager
    Dim swSketch As Sketch
    Dim swCircle As SketchSegment
    
    Set swApp = Application.SldWorks
    Set swModel = swApp.NewDocument("C:\path\to\template\part.prtdot", 0, 0, 0)
    
    Set swPart = swModel
    Set swSketchMgr = swPart.SketchManager
    
    swSketchMgr.InsertSketch True
    
    Set swSketch = swPart.ActiveSketch
    
    Set swCircle = swSketch.CreateCircle(0, 0, 0, 1, 0, 0)
    
    swModel.ClearSelection2 True
    swModel.ViewZoomtofit2
    
    Set swApp = Nothing
End Sub

This example demonstrates how VBA can be used to automate the creation of a new part document in SolidWorks and add a sketch with a circle. You can further enhance this macro by adding dimensions, features, or customizing it to suit your specific requirements.

Conclusion

In conclusion, VBA is the language behind SolidWorks macros. With VBA, you can harness the power of automation and customization in SolidWorks to streamline your design process and increase productivity.

Whether you are a beginner or an experienced programmer, learning VBA for SolidWorks macros will undoubtedly prove valuable in unlocking the full potential of this industry-leading CAD software.
