To Create a Curve in a Survey Figure Using the Chord Deflection

Create a non-tangential curve using the chord deflection.

1. In Toolspace, on the Survey tab, right-click a named network Survey Command Window.
2. At the Command line, enter:

   XC DD BULB [radius] [chord deflection] [chord distance]

Command Syntax

XC ZD BULB [radius] [chord deflection] [chord distance]

Parameter	Definition
BULB	Creates a curve that is greater than 180°.
radius	The distance from a center point to the curve. Enter this value in the current survey database distance units. Use a negative radius to draw the curve in a counter-clockwise (left) direction.
chord quadrant bearing	The desired quadrant bearing. Enter this value in the current survey database angular units, either DMS, grads, decimal degrees, mils, or radians.
chord distance	The distance from the current vertex in the figure. Enter this value in the current survey database distance units.
