CHAPTER 5 SELECTION 185 Basically, making the handle longer will make the curve stronger, while rotating the handle around its axis (the control point) will move the apex of the curve. If you don t like the handles, you can just click on the path segment and drag it directly. You can use paths that are composed of all straight lines, all curved lines, or any combination of the two. Usually, it s easiest to use straight lines for most of the path, and then curve only the few segments that follow tricky outlines. (Alternatively, you can just use more points for the tricky sections, and never use handles or curved segments at all.) Tip A path consisting only of straight lines is called polygonal. You can prevent handles from appearing on new points by checking the Polygonal box in the Paths tool options. (If you have existing points whose handles you ve adjusted, Polygonal won t remove their handles.) Adding Nodes or Segments and Moving Paths Edit mode is useful for more than just curving line segments. You can also use it to add a new control point between two existing points. Just click along the path (make sure the cursor is a + ) wherever you want the new point. This can be slightly confusing, because Edit mode assumes you want handles, so the new point will be created with two handles already visible. If you don t intend to use handles, you can avoid this confusion by checking the Polygonal box in the Paths tool options. Even if you do intend to use handles, you can still use this trick. Check Polygonal first, lay out your path, and then uncheck Polygonal and make handles for any control points you wish to use for curves. You can also make a path that includes several disconnected path segments. Pay attention to which points are drawn with a closed circle versus an open or dotted circle. Any point that s open or dotted is selected. Most of the time when you re creating paths, only one node, the last one created, will be selected. Creating a new point draws a line from the selected point to the new one. But you can deselect a node by Shift-clicking on it, or select more than one node by Shift- clicking on each new point you want to select. If there are no nodes selected, or more than one, or a node that isn t the end of a path, then clicking in a new location will begin a new disconnected path segment. Disconnected paths are useful mostly for making discontinuous selections or figures. They can be a time-saver since you can stroke or fill several areas at once. They re not generally used for making selections. If you have multiple points selected, dragging any one of them will also move other selected nodes by the same amount. Moving or Modifying an Existing Path The Paths tool has one more mode: Move mode. This allows you to move the entire path (not just one point, as in Design mode). Just click anywhere on the path and drag it to a new location. If you have more than one path segment, only the segment you drag will move. If you want all path segments to move, using Shift-drag will move them all at once. If you change windows or choose another tool after working with a path, when you go back to the window the path is no longer visible. How do you go on working with an existing path?
