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.
