Parametric Modeling: Master the Art of Modifiable Designs

Question 1

How do geometric constraints help maintain a design's original intent when making changes in parametric modeling?

Accepted Answer

Constraints keep design relationships intact, preventing unintended changes and ensuring model integrity.
