How many dimension lines do isometric drawings typically have?

Explanation:
Isometric drawings express depth by using three principal directions that correspond to length, width, and height, each along its own axis spaced equally from the others. Dimension lines are placed along those three directions to show the size in each dimension. Since there are three independent directions in an isometric view, there are three dimension lines. You might add more dimension notes for details, but the standard is three to convey the three dimensions.
