E. If you select a point that has been placed on an

placed on a circle will remain on that circle regardless of how

you move the point.

E. A

point is automatically created midway between those two

points.

the Midpoint tool and pressing

E adds a point midway

between the ends of that object. (In the case of a circle, the

midpoint is created at the circle’s center.)

Center Tap a circle and press

E. A point is created at the

center of the circle.

Intersection Tap the desired intersection and press E. A point is

created at one of the points of intersection.

Keyboard shortcut:

Intersections Tap one object other than a point and press E. Tap

another object and press

E. The point(s) where the two

objects intersect are created and named. Note that an

intersections object is created in Symbolic view even if the two

objects selected do not intersect.
