Choosing a Design Data Point
This section is a continuation of the topic Controlling the Label Placement in
this chapter.
The Design Data Point works in conjunction with the Label Location to
determine where the label is placed on the drawing. If you choose a Label
Location that is based on increments, then the Design Data Point also
determines what the increment value is related to, such as a station increment
or elevation increment. For example, you may set the Design Data Point to
station if you intend to label information at stations along an alignment.
The following illustration shows the Design Data Point scroll list under the
Label Placement Data section of the Edit Attached Text Labels dialog box:
The options that appear in this list are determined by the Code Category and
Code that you set for the style. For example, with a style that labels existing
ground profile elevations there are three Design Data Point options:
n
Station: Places elevations at a station increment; for example, every 50'
along the profile.
n
Elevation: Places the elevations at an elevation increment; for example, to
place labels along the profile wherever an even 0.25' occurs.
n
Grade Break: Places elevations along the profile where the existing ground
grade breaks occur.
The Design Data Point option that you specify is not necessarily the
information that is being labeled. For example, you would set the Design Data
Point to Station in order to label an existing ground profile elevation at a
station increment, but the label contains elevation information.
