Specify a point of beginning as a base point, and optionally specify another location as the point of closure.
When you specify a point of beginning, the Coordinate Geometry Editor requires that you specify a point of closure:
- Use the point of beginning as the point of closure, which creates a closed traverse loop.
- Specify a different control point as the point of closure, which keeps the traverse loop open.
Specify a point of beginning and a point of closure using either COGO point data or Easting and Northing values:
Point Name/Number
Easting (X) and Northing (Y)
- Enter a COGO point name or number.
- Click
to select a COGO point in the drawing. - Enter coordinates in the Easting (X) and Northing (Y) cells.
- Click
to specify an Easting (X) and Northing (Y) location in the drawing.
In the drawing, glyphs are displayed to indicate the point of beginning 
and point of closure 
.
