Representing Dimensions

At first glance, the rows of dimensions on the floor plan of a house may look confusing. Look at Figure 3.1. To make the dimensions easier to find and read, the draftsperson has labelled some of them. Buildings with a simpler layout may show just the dimensions without the labels. If you’re not sure which dimension a wall lines up with, use a ruler or other straight edge to make it easier to check.

Note that the dimension style used in Figure 3.1 uses large dots as the terminators of a dimension (to show where it starts and stops). Other drawings might use arrows or slashes as terminators, as shown here.
