This is the cornerstone of any CAD tool. Plugins allow users to click on an object and instantly generate dimension lines with arrows and text. The critical feature is "association"—if you stretch the object, the dimension number automatically updates to reflect the new size.

Currently, the market is dominated by a few key players that have integrated deeply with Adobe’s architecture:

Adobe Illustrator is the industry standard for vector graphic design, celebrated for its flexibility, creative tools, and Bezier curve precision. However, for users in the fields of engineering, architecture, industrial design, and technical illustration, Illustrator’s native toolset often falls short. It lacks the dimensioning, scaling, and geometric constraints found in dedicated CAD (Computer-Aided Design) software.
