Open Model

Overview​

This video demonstrates the Open Model command in Nitro-CELL, which allows engineers to open PTC Creo Parametric models directly from an Excel worksheet. The command takes a model name and optional file path as arguments, then instructs Creo to locate and open the specified part, assembly, or drawing. This is typically the first command in any automation workflow, as subsequent operations like setting parameters or saving require a model to be active in the Creo session. The video shows how to enter the Open command in the execution worksheet, specify the model filename, and handle common scenarios such as models in different directories or workspace locations. It also covers error handling when a model cannot be found.

Key Steps​

  1. Enter the Open Model command in the execution worksheet with the target model name
  2. Specify the file path or working directory if the model is not in the default location
  3. Execute the command to open the model in the active Creo session
  4. Verify the model opened successfully by checking the status column
  5. Proceed with additional commands now that the model is active in Creo

Tips​

  • Ensure the model file exists in the specified path before running the Open command
  • Use the working directory setting to avoid specifying full paths for every model
  • The Open command supports parts, assemblies, and drawings
