If you need to match a contiguous selection of
texture vertices to an outline in a bitmap, whether
an ir regular shape, a straig ht line, or a geometric
shape, you can use the Sketch tool to perform
the operation quickly, rather than dragging the
vertices one at a time.
Procedure
Ex ample: To sketch textur e vertices f ree for m:
You can start with the vertices already selected, or
use the Sketch tool to select them. In this example,
we’ll assume the latter.
1. Choose Sketch Vertices.
2. In the Sketch Tool dialog, next to Select By,
choose Drag Selec tion, if necessary.
3. Next to Align To, choose Free Form, if
necessar y.
4. Make sure Show Vertex Order and Interactive
Mode are tur ned on. Leave Drag Cursor Size
at the default setting.
5. Click OK to close the dialog.
The mouse cursor takes the form of a circle,
which means you’re in “drag select” mode.
6. Intheeditorwindow,dragthecursoroverthe
vertices to select, and then release the mouse
button.
As you drag, each vertex is assig ned a
consecutive number. When you release the
mousebutton,thecursorturnsintoapencil,
which means you’re in “sketch” mode.
Note: Before you start sketching, each successive
mouse click alternates between drag and sketch
modes.
7. In the editor window, drag a wavy line.
The selected vertices follow the line in numeric
order, spreading out evenly over its length. To
start the sketch over, release the mouse button,
and then drag again.
Alternatively,ifyoupressandholdALT,and
the press and release the mouse button, you’ll
draw a straight line by moving the mouse. Click
