Calculation of contour geometry
The MANUALplus automatically calculates all missing coordinates,
points of intersection, center points, etc. that can be derived
mathematically.
If the entered data permit several mathematically possible solutions,
you can inspect the individual solutions and select the proposal that
matches the drawing.
Each unresolved contour element is represented by a small symbol
below the graphic window. The control displays all contour elements
that can be drawn, even if they are not yet fully defined.
