42. 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?
Watch video that shows changing part length to demonstrate parametric modeling.
Video quality is not great, but shows the idea of parametric modeling.
Discuss during the video the expansion of extrusion 1 in the browser so that Sketch 1 is shown. Right click on Sketch1 and choose Edit Sketch. Double click on length dimension to change 3 to a 5. Press update to show the changed length of the part.
