The available evidence does not identify a supported location or reference for replacing the VI created by File > New VI. It does support a lower-risk alternative: save the desired starting design as a VI template and select it through New... > VI > From Template. This preserves installed behavior while allowing multiple reusable starting configurations.
Choose the Supported Workflow
| Requirement | Evidence-supported decision | Known limitation |
|---|---|---|
| Create a VI from a customized starting design | Use the VIT template workflow | Requires additional selections in the New dialog |
| Maintain several starting designs | Select among multiple VI templates | No automatic template selection is established |
| Replace the VI opened by File > New VI | No verified procedure is available in the evidence | The required file location or reference is unknown |
| Control Create SubVI output | No verified procedure is available in the evidence | The template relationship is not established |
Configure a Reusable VI Template
- Prepare a VI with the front-panel, block-diagram, window, and connector-pane configuration that new VIs should inherit.
- Save that design as a VIT template.
- Open New... > VI > From Template.
- Select the required template and create the new VI from it.
This method avoids overriding installed functionality and lets engineers keep different templates for different VI roles. It is particularly useful when a defined connector-pane arrangement prevents repeated connector removal or reconfiguration.
Verify the Result and Boundaries
Create a VI from the template and confirm that its window configuration and connector pane match the saved design. Then close the generated VI and verify that the template itself remains unchanged.
Do not assume that the VIT workflow changes File > New VI or the result of selecting code and invoking Create SubVI. The evidence provides no confirmed mapping between those commands and a user-supplied default template. It also reports unusual save-prompt behavior after changing and closing a default-related VI, but does not establish a cause or a reliable procedure; protect the template by saving changes explicitly before closing it.
FAQ
How do I create a LabVIEW VI from my own template?
Save the prepared VI as a VIT template, then use New... > VI > From Template and select it.
Can a VIT automatically replace File > New VI?
The evidence does not confirm an automatic replacement method or the required default-file location. Use the explicit template-selection workflow unless a verified version-specific procedure is available.
Does a custom VI template control Create SubVI?
No relationship between a user-supplied VIT and Create SubVI is established by the evidence. Verify that workflow separately before relying on it for connector-pane or window configuration.
