You ll immediately appreciate the effect of a symmetrical node when you drag one control point away from a node the opposing control handle moves an equal distance from the node in exactly the opposite direction. The artistic effect is that the two joined path segments take on an almost circular appearance which is very useful for technical illustration work. Drawing with the Bezier and Pen Tools Both of these tools are used to create compound paths segments connected by a common node by combining a series of clicks or click-drags but each is used in slightly different ways for different results. Using either of these tools single-clicks define new node positions joined by straight segments. Curve segments are created by clicking to define the node position and then dragging to define the curve shape. Click-dragging in succession creates a continuous curved path shaped by multiple nodes and off-the-curve control handles. While using the Bezier tool each click-drag defines and completes the curve segment. A little differently while using the Pen tool the cursor remains active and a preview of the next curve segment appears so you can define both the curve shape and the next node point. Double-clicking ends the series of path segments. TIP When drawing with the Bezier tool holding CTRL as you click to create new nodes constrains their position to align vertically horizontally or within constrained angles relative to the last created node position. Holding CTRL while dragging curve handles constrains their angles to 15-degree increments relative to the last node created. Let s try out a new drawing method. Drawing Curves and Straight Line Segments 1. Choose either the Bezier tool or the Pen tool and use a single click to define the first node position of your path. Click again to define a second point somewhere else on your page. The two nodes are now joined by a straight line. 2. .
