Working with sheet metal parts in SolidWorks often involves exporting DXF files for manufacturing. If you handle large assemblies or multiple parts, manually exporting each sheet metal part can be time-consuming. Luckily, you can automate the process using SolidWorks VBA (Visual Basic for Applications), allowing you to export 1:1 scale DXF files directly from your assembly, ensuring accuracy and efficiency.

In this tutorial, we’ll walk you through automating the DXF export of sheet metal parts using VBA in SolidWorks. This solution will save you time and help you streamline your workflow, especially for complex assemblies.

Why Automate Sheet Metal DXF Export in SolidWorks?

Automating the DXF export process in SolidWorks VBA offers several benefits:

• Efficiency: Automatically export all sheet metal parts from an assembly at once.
• Accuracy: Ensures consistent 1:1 DXF exports for manufacturing.
• Time-Saving: Eliminates the manual process of opening each part and exporting individually.

Automating the Process with VBA in SolidWorks

To begin automating the process, we’ll create a SolidWorks VBA macro that checks for sheet metal parts in the assembly and exports them as DXF files in a 1:1 scale.

Requirements:

• SolidWorks
• Basic understanding of VBA and macros

Step-by-Step Guide to Creating the VBA Macro

1. Open SolidWorks and Create a Macro

In SolidWorks, go to Tools > Macro > New and save the macro file in an accessible location. You will write the VBA code that automates the export process.

2. VBA Code for Automating DXF Export

In the VBA editor, use the following code. This macro loops through all components in the assembly, checks if the part is a sheet metal part, and automatically exports it as a DXF file.

How This VBA Macro Works:

• Assembly Check: The macro first verifies if the active document is an assembly. If not, it alerts the user to open an assembly.
• Sheet Metal Part Detection: It loops through all components and checks if the part is sheet metal using the feature type “SheetMetal.”
• DXF Export: Once a sheet metal part is found, it automatically exports the part as a DXF file in 1:1 scale.
• Saving the DXF Files: The macro saves the exported DXF files in the specified directory.

3. Customize the Macro

You can modify the saveDir variable to choose where the DXF files are saved. Customize file naming conventions or add error handling if needed.

4. Running the Macro

Once you’ve written the macro, save it and return to SolidWorks. Open your assembly, navigate to Tools > Macro > Run, and select the macro file. The macro will automatically generate DXF files for all sheet metal parts in your assembly and save them in the specified directory.

Benefits of Automating with SolidWorks VBA

Automating DXF export for sheet metal parts using VBA saves time, ensures accuracy, and streamlines the design-to-manufacture process, especially when working with large assemblies in SolidWorks. The use of VBA macros allows for complete customization and control over your workflow.
