Computer-Aided Design (CAD) uses a computer program to create, analyze, and modify iterations of a design in order to optimize it.
CAD has generally replaced hand drafting and has streamlined construction documentation. Because it’s a fast electronic process, there is essentially no cost to exploring multiple design options, and modeling component performance.
Uses Of CAD Design
Model and test multiple design iterations in the concept stage. Provides a low-cost method to apply creativity and think "outside the box" doing multiple “what if” scenarios.
Provide quick answers to questions of materials selection, usage, and fit.
Using CAD plans, it’s easy to correct performance or manufacturing problems by adjusting design or materials.
Examine and improve engineering, manufacturing, and quality processes. Correct issues before going to production.
