Dividing, extending and shortening contour elements
If contour elements to be selected in the drawing connect poorly, then
you must first divide the contour element. This function is
automatically available if you are in the mode for selecting a contour.
Proceed as follows:
U
The poorly connecting contour element is selected, so it is colored
blue.
U
Click the contour element to be divided: The TNC shows the point
of intersection with a star in a circle, and the selectable end points
with simple stars.
U
Press the CTRL key and click the point of intersection: The TNC
divides the contour element at the point of intersection and the stars
disappear. If there is a gap, or the elements overlap, the TNC
extends or shortens these poorly connecting contour element to the
point of intersection of the two elements.
U
Click the divided contour element again: The TNC shows the end
points and points of intersection again.
U
Click the desired end point: The TNC now colors the divided element
blue.
U
Select the next contour element.
If the contour element to be extended or shortened is a
straight line, then the TNC extends the contour element
along the same line. If the contour element to be
extended or shortened is a circular arc, then the TNC
extends/shortens the contour element along the same
arc.
In order to use this function, at least two contour
elements must already be selected, so that the direction
is clearly determined.
Element information
At the bottom left of the screen, the TNC displays information about
the contour element that you last selected via mouse click in the left
or right window.
Straight line
End point of the straight line, and the starting point is grayed out
Circle or arc
Circle center point, circle end point, and direction of rotation. Grayed
out: the starting point and circle radius
