model : FAMILY_TBL_OPEN_INST

Overview​

This video demonstrates the FAMILY_TBL_OPEN_INST command in Nitro-CELL, which opens a specific family table instance of a Creo Parametric model. Family tables define multiple variations of a generic model, and this command allows engineers to programmatically open a named instance directly from Excel. The command takes the generic model name and the instance name as arguments, then instructs Creo to retrieve and open that specific variation. This is essential for workflows that need to inspect, modify, or export individual instances without manually navigating the family table dialog in Creo. The video covers entering the command, specifying the instance, and verifying the correct instance opened.

Key Steps​

  1. Ensure the generic model is accessible in the working directory or session
  2. Enter the FAMILY_TBL_OPEN_INST command with the model and instance names
  3. Execute the command to open the specified instance in Creo
  4. Verify the correct instance is now active in the Creo session
  5. Proceed with additional operations on the opened instance

Tips​

  • The generic model must be available for Creo to resolve the instance
  • Combine with FAMILY_TBL_INST_EXISTS to validate before opening
  • Works with both part and assembly family table instances
