Set Parameter

Overview​

This video demonstrates the Set Parameter command in Nitro-CELL, which assigns a value to an existing parameter on the active Creo model. Parameters in Creo store metadata such as part numbers, descriptions, materials, and custom attributes. The Set Parameter command allows engineers to update these values directly from an Excel worksheet without opening the Creo parameter dialog. The video shows how to specify the parameter name and new value in the execution worksheet, execute the command, and verify the parameter was updated in Creo. This is one of the most commonly used Nitro-CELL commands, forming the backbone of bulk parameter update workflows across parts and assemblies.

Key Steps​

  1. Ensure the target model is open in the Creo session
  2. Enter the Set Parameter command with the parameter name and new value
  3. Execute the command to update the parameter on the active model
  4. Verify the parameter value was changed by checking the Creo model properties
  5. Regenerate and save the model to persist the parameter change

Tips​

  • The parameter must already exist on the model — use SetCreate if it might not exist
  • Match the parameter data type (string, integer, real) to avoid type mismatch errors
  • Combine Set Parameter with data worksheets to update parameters across many models
