Chapter 9 Entering & Modifying Points
Entering a Point to Create a Tangent
Tangent snap makes it easy to enter a point that creates a line tangent to an
existing arc or circle. As you move the pointer over the drawing, the
AutoPoint Indicator identifies the nearest point tangent to the original point.
To enter a point that creates a line tangent to an arc or circle
1 While in a drawing mode, activate Tangent snap on the Snaps toolbar.
2 Click the entity. Because there are two tangent points, you must click near
the tangent point you want to use.
Entering a Quadrant Point on an Arc
or Circle
Quadrant snap allows you to enter a point that coincides with a quadrant
snap point on an arc or circle. As you move the pointer over the entity, the
AutoPoint Indicator identifies the nearest quadrant point. Normally, there
are four such points, however, you can specify up to 72 evenly spaced snap
points.
