Marking the Intersection between a Line and an Arc

Mark the points of intersection between a line and a wire arc or circle.

\intla

 

Indicate the arc and the line.

The points of intersection are marked by short help line crosses. If the line does not intersect the arc, the line is extended by a help line. If the arc does not meet the line, the crosses are drawn at points that are extensions of the arc. The crosses indicate the exact point of intersection with the true arc or circle.
