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?Slide39

Why Parametric Modeling?

Benefits

Shape before size

Geometric and dimension constraints used to capture design intentAll files can be quickly updated

Existing data can be used for new designsQuick design turn around
