Create a non-tangential curve using the chord deflection.
- In Toolspace, on the Survey tab, right-click a named network
Survey Command Window. - 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 bearing | The desired 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. |
