Selecting a reference point on the intersection of two elements
 Select the mode for specifying the reference point.
 Click the first element (straight line, complete circle or
circular arc) with the left mouse button. The TNC
indicates possible locations for reference points on
the selected element with stars.
 Click the second element (straight line, complete
circle or circular arc) with the left mouse button. The
TNC sets the reference-point symbol on the
intersection.
Element information
At the bottom left of the screen, the TNC shows how far the reference
point you haven chosen is located from the drawing datum.
The TNC calculates the intersection of two elements even
if it is on the extension of one of these elements.
If the TNC calculates multiple intersections, it selects the
intersection nearest the mouse-click on the second
element.
If the TNC cannot calculate an intersection, it rescinds the
marking of the first element.
