How to Select 3D Model Tree Parts Using Excel VBA
Question details
The user needs a way to automatically select specific parts within a 3D model tree when opening the model using an Excel VBA macro.
- Product
- Excel VBA / 3D Viewer Applications
- Device & OS
- not provided
- Scenario
- Automating the selection of components in a 3D model directly from spreadsheet macros to streamline workflows.
- Observed behavior
- Requires a programmatic method to interact with a 3D model's internal tree structure through Excel VBA scripts.
Before writing your script, determine the exact application (such as SolidWorks, AutoCAD, or Adobe Acrobat for 3D PDFs) that will display the model, as you must reference its specific object library in your VBA editor.
Use Application-Specific Object Models via Excel VBA
Reference the target 3D application's API library in the Excel VBA editor to manipulate the model tree programmatically.
Because Excel VBA does not natively parse 3D models, it must communicate with the third-party software that renders the model. Most professional CAD or 3D viewing applications provide COM add-ins or object libraries that you can reference directly in the Excel VBA environment to interact with the model tree.
Verify the software used to open the 3D model, its version, and the file format, as this dictates which API documentation you will need to follow.
Press ALT + F11 to open the VBA Editor in Excel. Navigate to 'Tools' > 'References' in the top menu, scroll down the list, and check the box corresponding to your 3D application's object library.
Declare the required application objects in your module. Use the software's specific API methods (for example, navigating the tree nodes and setting a node's 'Selected' property to True) to execute the part selection.
Run VBA Scripts to Automate Tasks in WPS Spreadsheet
WPS Office offers robust VBA support, allowing you to seamlessly run macros, reference external application object libraries, and automate interactions with 3D modeling software just like Microsoft Excel.
- 1. Enable Developer Tools: Open WPS Spreadsheet, go to the 'Developer' tab on the ribbon, and click 'Macros' to access the built-in VBA environment.
- 2. Reference External Libraries: In the WPS VBA Editor, navigate to 'Tools' > 'References' to load your target 3D application's object model into the project.
- 3. Execute the Code: Paste or write your automation script in a new module and press 'Run' to manipulate your 3D models directly from your WPS spreadsheet.
Frequently Asked Questions
Can I select 3D model parts in a standard Excel 3D chart using VBA?
No, standard Excel charts do not have a 3D model tree structure. You must use an external 3D viewer or CAD software embedded as an OLE object, and utilize its specific API via VBA.
How do I interact with a 3D PDF using Excel VBA?
To interact with 3D PDFs, you need to leverage Adobe Acrobat's JavaScript API. You can use Excel VBA to launch the Acrobat application object and pass JavaScript commands to manipulate the 3D annotation's model tree.
Why is my 3D application's object library missing from the VBA references list?
The object library will only appear if the 3D application is properly installed on your computer. If it is installed but missing, click 'Browse' in the References dialog and manually locate the application's .tlb, .olb, or .exe file.
