* Coordinate system: A system of axes used to define the position and orientation of objects in a drawing.
* Drawing editor: A tool that allows you to create and modify drawings.
* Entity: A geometric object that makes up a drawing, such as a line, circle, or text.
* Layer: A grouping mechanism that organizes entities in a drawing.
* Viewport: A window that displays a specific portion of a drawing.

CommandsAutoCAD English is command-driven, meaning you interact with the software using commands. Here are some of the most frequently used commands:* LINE: Creates a straight line.
