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

Create a non-tangential curve using the chord bearing.

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

   XC BD BULB [radius] [chord bearing] [quadrant] [chord distance]

Command Syntax

XC BD BULB [radius] [chord bearing] [quadrant] [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 bearing	The desired bearing. Enter this value in the current survey database angular units, either DMS, grads, decimal degrees, mils, or radians.
quadrant	Specify the quadrant using one of the following numbers: 1 (for NE), 2 (for SE), 3 (for SW), or 4 (for NW).
chord distance	The distance from the current vertex in the figure. Enter this value in the current survey database distance units.
