Press ENTER, and you are prompted for the start

determine how the spline is displayed.

Return the cursor to the start point of the spline

to locate the start tangent point, and then do the

same for the end tangent point.

You may have to experiment with the placement of the start and end

tangent points. After you draw a spline curve, you can edit it with

Hatch Patterns

In a complex drawing, you can distinguish some areas from other

Key Concepts

■

■

You can define the area to be hatched either by specifying a point

inside a boundary, or by selecting an object to be hatched, if it is a

closed object.
