How does CAD improve the accuracy of manual drawing methods?

Using CAD (Computer-Aided Design) significantly enhances the accuracy of manual drawing methods primarily because it allows for easy adjustments. In manual drawing, making corrections can often be cumbersome and may lead to further errors if not executed carefully. CAD software, on the other hand, provides tools that enable designers to easily modify dimensions, shapes, and details without the need to start over or create entirely new drawings. This capability reduces the potential for human error, as adjustments can be made with precision using features like snap-to-grid, scaling, and layer organization.

Furthermore, the ability to undo or redo changes instantly in CAD applications also helps ensure that any mistakes can be quickly rectified. This level of flexibility and control that CAD offers is not possible to the same extent with traditional manual drawing techniques, where adjusting one element often affects other parts of the drawing, leading to potential inaccuracies.

Other answers may address different benefits of CAD; for example, while some might think it eliminates mistakes entirely, this is not feasible as human error can still occur through design decisions. Speeding up the drawing process or simplifying design complexity, while advantages of CAD, do not directly correlate to the enhancement of accuracy in the same way that the ability to make adjustments does. Therefore, the primary benefit of
