Setting a preset
The datum of the drawing in the CAD file is not always located in
a manner that lets you use it as a workpiece preset. Therefore, the
control provides a function with which you can shift the workpiece
preset to a suitable location by clicking an element. You can also
define the orientation of the coordinate system.
You can position the preset at the following locations:
By directly inputting numerical values into the List View window
For straight lines:
Starting point
Center
End point
For circular arcs:
Starting point
Center
End point
For full circles:
At the quadrant transitions
At the center
At the intersection between:
Two straight lines, even if the point of intersection is actually
on the extension of one of the lines
Straight line and circular arc
Straight line and full circle
Two circles (regardless of whether a circular arc or a full
circle)
Operating note:
You can change the preset even after you have selected
the contour. The control does not calculate the actual
contour data until you save the selected contour in a
contour program.
