XC AD BULB [radius] [chord angle] [chord distance]
Parameter | Definition |
---|---|
radius | The distance from a center point to the curve. Enter this value in current survey database distance units. Use a negative radius to draw the curve in a counter-clockwise (left) direction. |
chord angle | The clockwise angle to turn from the last vertex in the figure. |
chord distance | The distance from the current vertex in the figure. |
