TWO POINTS AND AMPLITUDE

Purpose:

To allow the user to define a polyline segment as an arc using two end two points and amplitude (last point of previous segment used as first point).

Instructions:

1. Enter the amplitude in the value field in the Geometry toolbar. Instead of giving an explicit amplitude, the value Indicate can be selected from the combo box.

2. Define the end point of the arc. The resulting arc will be defined with given amplitude.

3. If the amplitude has been defined implicit (as 'Indicate') a third point is required to give the amplitude.
