Intersection Point(s)
The
Intersection Point(s)
tool creates a point at the intersection (or intersections) of any two objects.
An intersection can be defined for only two objects. If more than two objects intersect at the same
place (for example, the perpendicular bisectors of a triangle), an ambiguity message appears. If
this happens, hold down the mouse button and select the correct object from the list.
If you change the objects so that they no longer intersect, the intersection point(s) disappears, but
reappears if the objects intersect again.
Creating an intersection point
1.
Select
Intersection
Point(s)
from the
Points
toolbox.
2.
Select two intersecting objects.
Select the first object.
Select the second object.
Points are created
at each intersection.
Modifying an intersection point
Intersection points are dependent and cannot be moved.
Example
Intersection of a line and a polygon:
Select polygon and line.
Points are created at each
intersection.
