Nitro-PROGRAM, RELATIONS

Overview

This video demonstrates how to work with RELATIONS in Pro/PROGRAM using Nitro-PROGRAM. RELATIONS define mathematical equations and expressions that link parameters and dimensions within a Creo model, enabling parametric design intent. The video shows how to add, edit, and manage relation entries through the graphical editor, including defining equations that calculate parameter values based on other parameters or dimensions. It covers how Nitro-PROGRAM presents relations in a clear visual format, making it easy to review and modify the mathematical relationships that drive model geometry without editing raw Pro/PROGRAM text.

Key Steps

1. Open a Creo model and launch Nitro-PROGRAM to access the Pro/PROGRAM
2. Navigate to the RELATIONS section of the program editor
3. Add new relation entries defining equations between parameters and dimensions
4. Edit existing relations to update mathematical expressions
5. Write the program and regenerate to verify the relations produce correct values

Tips

• Relations are evaluated during regeneration — ensure all referenced parameters exist
• Use relations to derive calculated values rather than hard-coding numbers
• Keep relation expressions simple and well-organized for easier maintenance
