Creating contour paths independent of available contour elements
To select any contours by using the end point, center, or transition
points:
Select the contour selection mode
Activate the "Add contour elements" mode
The control displays the following icon:
Place the mouse pointer on the contour element
The control displays selectable points.
Select the starting point as needed
Select the starting element
Select the subsequent element
Alternative: Select any selectable point
The control creates the desired contour path.
Operating notes:
The contour paths available depend on the selectable
contour elements that are shown in green. Without the
green elements, the control will display all solutions
available. To remove the proposed contour path,
select the first green element by pressing the left
mouse button while holding the CTRL key down.
As an alternative, you can switch to the Remove
mode:
If the contour element to be extended or shortened is
a straight line, the control will extend or shorten the
contour element along the same line. If the contour
element to be extended or shortened is a circular arc,
the control will extend or shorten the contour element
along the same arc.
