tbl_model : FAMILY_TBL_INST_EXISTS

Overview​

This video demonstrates the tbl_model FAMILY_TBL_INST_EXISTS command in Nitro-CELL, which checks whether specific family table instances exist across models listed in an Excel table. Each row in the table specifies a model and an instance name to check. The command returns a boolean for each row indicating whether that instance is defined in the model's family table. This is valuable for validating instance availability across multiple models before attempting to open or process them, preventing errors in batch workflows. The video covers setting up the table, executing the check, and reviewing the results.

Key Steps​

  1. Create an Excel table with model names and instance names to check
  2. Enter the tbl_model FAMILY_TBL_INST_EXISTS command referencing the table
  3. Execute the command to check instance existence across all models
  4. Review the boolean results for each model-instance pair
  5. Use the results to filter which instances to open or process next

Tips​

  • Each row can check a different model and instance combination
  • Use as validation before running FAMILY_TBL_OPEN_INST in batch
  • Instance names must match exactly as defined in the family table
