Table describing conventions for denoting dimensions on figures

Table 1
Graphic Conventions

The table describes graphic conventions for showing dimensions on figures between boundary and element lines, how the direction of approach is denoted, centerline designation and boundary of clear floor area. All dimensions are shown in inches above the measure line, with the metric equivalent below. Where the dimension does not fit conveniently between lines, the measure line is extended beyond the lines and the dimension placed above (and below) the extension.
