Which command is used to measure the distance between two points?

The command that measures the distance between two points is DIST. When you use the DIST command in AutoCAD, you simply click on the two points you want to measure, and the command returns the distance between them, along with the coordinates of both points. This command is quick and straightforward, providing a direct way to obtain distance measurements without needing to set up any dimensions or annotations.

The other options listed are not primarily used for measuring distances between points in the same straightforward manner as DIST. For example, while the MEASURE command is related to distance, it is used to create geometry based on a specified length rather than just measuring the distance between two points. DIMLINEAR is used for creating linear dimension annotations, which is helpful for documenting measurements but does not simply provide a distance reading. RULER, meanwhile, refers more to an interface element that may assist users with measurements rather than functioning as a command for instantaneous distance calculations.
