Parametric design (parametrisch ontwerp) is een begrip binnen de industriële digitalisering en innovatie & toekomsttrends.
Definitie
Parametric design (parametrisch ontwerp) definieert ontwerpen door parameters en regels die automatisch aanpassingen doorvoeren wanneer input-waarden wijzigen. Het enables snelle iteraties en massa-customization door relationele geometrie en constraint-based modeling.
Kenmerken
- Rule-based modeling: Design constraints en relationships defining geometry
- Associative geometry: Changes cascade through related design elements
- Variable-driven design: Parameters control dimensions, features en properties
- History-based workflow: Design intent preserved through feature history
- Constraint solving: Automatic geometry adjustment maintaining design relationships
- Family tables: Multiple variants generated from single parametric model
- Design automation: Scripts en templates enabling rapid design generation
- What-if analysis: Quick exploration van design alternatives
- Intelligent regeneration: Automatic model updates when parameters change
