Description
The tool references another tool that is no longer valid. Invalid tools include an invalid tool, invalid script, or invalid model symbol. The tool either cannot be opened or does not exist. Some causes of this error include the following:
- A model is using an invalid tool or another model that cannot be found or is invalid.
- If the tool is a custom tool built by a third-party developer, the tool may not exist in a toolbox, may have a problem with the tool's implementation, or may not have been registered appropriately at the time it was shared.
Solution
Editing a model and immediately saving it may correct problems with parameter changes.
Solutions for custom tools include the following:
- Register, or reregister, the tool.
- Ensure that the tool is implemented and functions properly.
