Select contour
Operating note:
If you double-click a layer in the list view window, the
control switches to Contour Transfer mode and selects
the first contour element that was drawn. The control
highlights the other selectable elements of this contour
in green. Especially in case of contours with many short
elements, this procedure spares you the effort of running
a manual search for the beginning of a contour.
To select a contour using available contour elements:
Select the contour selection mode
Place the mouse pointer on the desired element
The control displays the suggested direction of
rotation as a dashed line.
If you need to change the direction of rotation,
move the mouse pointer towards the opposite
end point
Select the element using the left mouse button
The selected contour element turns blue.
The control shows the other selectable elements
in green.
Select the last green element of the desired
contour using the left mouse button
The control changes the color of all selected
elements to blue.
In the List View, all selected elements are given a
check mark in the column NC.

For branched contours, the control
chooses the path with the smallest
directional deviation. The control provides
an additional mode that allows you to
modify the suggested contour path.

paths independent of available contour
elements", Page 512
