In cross section templates (for ducts, segments, poles, and towers) snap points are used to position features. For example, in a segment cross section, snap points help you position ducts within the segment. In a duct cross section, snap points help you position conductors within the duct. The number of snap points determines the number of ducts that can be placed in a segment or conductors in a duct.
During data acquisition, use snap points to place a duct at the specified location in the segment cross section drawing.
When defining a segment cross section template, you digitize the snap points for the ducts and conductors, not the ducts and conductors themselves. You digitize ducts and conductors during data acquisition. Similarly, for overhead networks, when defining a node cross section template, you digitize the snap points for the conductors, not the conductors themselves.
Snap points can be assigned or unassigned.
- Assigned—Use assigned snap points for features whose exact location is known. These are used only in segment cross sections. These are given the numbering scheme, YYYXXX.
- Unassigned—Use unassigned snap points for features whose exact position is not known. For example, in duct templates you always use unassigned snap points. Similarly, when you add a conductor whose exact location in the segment is not yet known, use an unassigned snap point.
- Position Number—Use Position Number to automatically choose the next available location for contained ducts or conductors, or to specify data for other components of the template, such as labels or legend.
Position number represents the relative position of the snap point. The position number is the same in the different templates. This allows you to change the template if necessary. When you add new columns or remove rows, the position number of the existing items does not change.
You can specify the numbering used for position number to be sequential, order, or none. See Set Electric Options.
- Labels—Use labels for annotations, such as the order number or a legend. You can use both the snap point label feature class or any cross section label feature class.
