To Create a Curve in the Current Survey Figure

Create a curve in the current figure using two known variables.

1. In Toolspace, on the Survey tab, right-click a named network Survey Command Window.
2. In the Command line, enter any capitalized curve parameters, plus the radius and the curve parameter value:
   • CURVE DELTA [radius] [value]
   • CURVE LENGTH
   • CURVE DEFL
   • CURVE TANGENT
   • CURVE CHORD
   • CURVE MID

Command Syntax

CURVE DELTA [radius] [value]

CURVE LENGTH [radius] [value]

CURVE DEFL [radius] [value]

CURVE TANGENT [radius] [value]

CURVE CHORD [radius] [value]

CURVE MID [radius] [value]

Command Synonym

CURVE TAN

Parameter	Definition
DELTA	The value parameter indicates the angle of the circular curve.
LENGTH	The value parameter indicates the length of the circular curve.
DEFL	The value parameter indicates the deflection angle between the current figure direction and the chord.
TANGENT, TAN	The value parameter indicates the tangent distance of the curve.
CHORD	The value parameter indicates the chord length of the curve.
MID	The value parameter indicates the mid-ordinate distance of the desired curve.
radius	The distance from a center point to the curve. You must enter this value in the current survey database distance units. Use a negative radius to draw the curve in a counter-clockwise (left) direction.
value	A curve value that depends on the curve parameter that you specified. For example, if you specify CHORD, then the value is the chord length. You must enter all distances in the current survey database distance units, and angles in the current survey database angular units, either DMS, grads, decimal degrees, mils, or radians. If you enter a negative value, then the negative sign is ignored. The radius component described above is used to control the direction of the curve.
