Default UI Menu: Modes/Snaps/Apparent Intersection
Ribbon UI Menu:
Snaps to points where two lines would meet. An auxiliary line is displayed from both lines, extending to this point. Show Magnetic Point must be turned on.
- Start with lines whose extensions will meet (non-parallel). When you pass the cursor over each line, the line's endpoint is marked.
- When the cursor passes over any apparent intersection point, auxiliary lines will be displayed from the actual lines, and their intersection point is marked.
Note: If Always show auxiliary lines is checked in the Drawing Aids window, the auxiliary lines will be displayed, even when you move the cursor away from them.
