Which command is used to modify existing text in AutoCAD?

The command used to modify existing text in AutoCAD is DDEDIT. This command allows users to edit single-line and multi-line text objects directly within the drawing. When you invoke DDEDIT, it opens a text editor that provides a convenient interface for altering the text, such as changing its content, font, or size, and allows you to see the modifications in real-time within the drawing environment.

This command is especially useful when you need to make quick edits to annotations or labels in your drawing, enabling an efficient workflow. Understanding how to use DDEDIT effectively is essential for anyone working on detailed CAD projects, as these text modifications play a crucial role in conveying information clearly within technical drawings.
