ET Cogo

Allows the user to build traverses adding straight or curved courses using numerous parameters

	ET Cogo Dialog Define TakeOff point by: X & Y Interactively Start or End point of the selected feature Closest vertex of the selected feature Freehand Set Start Point button locates and assigns takeoff point for a traverse Traverse button opens traverse dialog Quit - ends the COGO session
	ET Traverse Dialog Current location Control Panel shows the coordinates of the last point of the traverse Next course , Curve Direction and Course parameters Control panels allow the user to define the geometry of the next course. The following combinations are possible: Straight Distance & Bearing X & Y dX & dY use the GetBearing tool to get the bearing from a feature from the active theme use +90 or -90 buttons to increase (decrease) the bearing with 90 degrees. the two features above allow adding courses parallel or perpendicular to existing features from the active theme Fillet - Distance,Bearing & Fillet radius Tangent curve (left or right to the previous course) Chord length & Delta Chord length & Radius Chord length & Arc Arc length & Radius Arc length & Delta Radius & Delta Non tangent curve (left or right to the previous course) Chord length, Chord Bearing & Radius Chord length, Chord Bearing & Arc length Chord length, Chord Bearing & Delta Note: A traverse can not start with Fillet or Tangent curve Add Course button adds a course with the predefined parameters to the traverse Undo - removes the last course of the traverse (multiple undo supported) Close Traverse - closes current traverse END button - if current theme is editable - adds the traverse as a feature in the theme otherwise creates a graphic shape in the view.

	By default the bearing is entered as Decimal Degrees - (45.2375). Hold the CONTROL key and click on the Bearing Text Line to introduce ET Azimuth dialog which allows the bearing to be entered as an Azimuth ((N 45 23 00 E). The direction is defined by the selected radio button.
