Instructions provided describe how to use tangent bearings in COGO. The tangent bearing can be used by finding the radial bearing, the bearing pointing to the curve's center, if the tangent bearing is going into the beginning point. Once the radial bearing is known, the TRAVERSE command can be used.
Users need to enter a curve with the following data:
The TRAVERSE command only accepts the following curve parameters:
radial direction (non-tangent curve)
Arcedit: &ty [calc [angrad s63-27-56e] + [angrad 90]]
Arcedit: &ty [radang 7.390868213232 -dms -bearing]
