Using the Adobe Title Designer
always has two direction lines that move together as a single, straight unit. When you drag
the direction point of either direction line on a smooth point, both direction lines move
simultaneously, maintaining a continuous curve at that anchor point. In comparison, a
corner point can have two, one, or no direction lines, depending on whether it joins two,
one, or no curved segments, respectively.
Drawing with the pen tool
Corner point direction lines maintain the corner by working independently of one
another. When you drag a direction point on a corner point's direction line, the other
direction line, if present, does not move. Direction lines are always tangent to (perpen-
dicular to the radius of) the curve at the anchor points. The angle of each direction line
determines the slope of the curve, and the length of each direction line determines the
height, or depth, of the curve.
The pen tools provide the most precise control over straight lines and curves. Using them,
you can easily adjust the shape of the connecting paths. You can also quickly add points to
or delete points from a segment, or change an anchor point from one type to another.
Once you draw lines or curves, you can either leave the connecting segments open,
meaning that the final segment does not return to the original starting point, or you can
close the connecting segments by clicking the initial control point.
To draw curves with the pen tool:
1 Select the pen tool.
2 Position the cursor where you want the curve to begin. Hold down the mouse button.
