Contour graphics
As soon as you have entered a contour element, the MANUALplus
checks whether the element is resolved or unresolved.
 A resolved element is a contour element that is fully and
unambiguously defined. It is drawn immediately.
 An unresolved element has not yet been fully defined by the
entered data. Use of the ICP editor:
 It places a symbol below the graphics window. It reflects the
element type and the line direction / direction of rotation.
 Represents an unresolved linear element if the starting point and
direction are known.
 Represents an unresolved circular element as a full circle if the
circle center and the radius are known.
As soon as it can be calculated, the MANUALplus converts an
unresolved contour element to a resolved contour element. The
symbol is then deleted.
An incorrect contour element is displayed if possible. In addition, an
error message is issued.
Unresolved contour elements: If during further contour input an
error results because there is not enough information, the unresolved
elements can be selected and supplemented.
If a contour contains "unresolved" contour elements, the "resolved"
elements cannot be changed. You can, however, set or delete the
"tangential transition" for the contour element located directly before
the unsolved contour area.
 If the element to be edited is an unresolved element,
the associated symbol is marked "selected."
 The element type and the direction of rotation of a
circular arc cannot be changed. In this case, the contour
element has to be deleted and then added.
