38. Why Parametric Modeling?
Gateway To Technology®
Unit 1 – Lesson 1.5 – Designing For Production
Why Parametric Modeling?
Determine the shape and size of the geometry at any time during the design process.
This part should
be 5 in. long, not
3 in. How can we
fix this without
redrawing it?
Use the Autodesk Inventor software to demonstrate parametric modeling.

39. Why Parametric Modeling?
Gateway To Technology®
Unit 1 – Lesson 1.5 – Designing For Production
Why Parametric Modeling?
Benefits
Shape before size
Geometric and dimension constraints used to capture design intent
All files can be quickly updated
Existing data can be used for new designs
Quick design turn around
