Which command would you use to create a straight line in AutoCAD?

To create a straight line in AutoCAD, utilizing the LINE command is the most straightforward approach. This command allows users to specify two points, which then creates a straight segment between those points. The simplicity in using this command is particularly beneficial for tasks that require quick and precise line drawings.

While there are other options available for creating lines, such as POLYLINE or SPLINE, those commands serve different purposes. The POLYLINE command allows for the creation of connected lines and arcs in a single object, which is useful for more complex shapes, but it is not specifically focused on creating a single straight line. Similarly, SPLINE is designed for creating curved lines and requires additional parameters to define the shape, making it unsuitable for drawing a direct line. The RECTANGLE command would be employed to create a four-sided figure, which inherently involves creating straight lines, but it is not the direct command for a simple line drawing.

Thus, for the task of drawing a single, straight line, the LINE command is the most appropriate choice.
