COGO > Update Attributes

Update Attributes

Update attributes will calculate the coordinate geometry descriptions for the selected COGO lines. For straight lines, you will get the distance and direction measurements of them in the attribute table. And for curved lines, you will get the chord, angle, radius, chord direction, arc length, and so on in the attribute table. The units are the same as the map unit. To get the information, you should add the corresponding field name to the table. For example, to get the distance of the straight line, you should add the 'distance' field to the table. The table below lists and describes the required table fields to maintain COGO attributes.

Field name	Description	Field alias	Format
Direction (or Angle)	The direction of the straight line. Or the direction of the chord line.	COGO Direction	Text Length=12
Distance	The distance between the endpoints for the straight line. Or the the distance along the chord line.	COGO Distance	Text Length=10
Delta	The central angle. Also referred to as angle.	COGO Delta	Text Length=10
Radius	The radius of the curve.	COGO Radius	Text Length=10
Tangent	The distance between the endpoint and the point of tangency.	COGO Tangent	Text Length=10
ArcLength	The length of the curve. Also referred to as Arc.	COGO ArcLength	Text Length=10
Side	The side on which the center point of the circular arc located.	COGO Side	Text Length=1
