Final answer:
Dimension lines are used in technical drawings to indicate the distance between two points and come with numerical values for precise measurements.
Step-by-step explanation:
The lines used to indicate distance between 2 points in a sketch are called dimension lines. Dimension lines are a fundamental aspect of technical drawing and drafting, typically accompanied by numerical values to specify the length of dimensions. They are very specific lines used to illustrate measurements on a drawing, which ensures precise communication in engineering and architectural projects.The lines used to indicate distance between two points in a sketch are called dimension lines. These lines help to measure and show the size of objects in a drawing. They are typically labeled with measurements to indicate the length or width of an object.
