Drawing constrained objects
Drawing constrained objects
The word constrain has a somewhat negative connotation, but in computer lingo, a
constraint is usually a good thing. If you apply a constraint to an object you draw, for example,
you force the object to adhere to a specific angle or proportion. Using constraints is the
easiest way to create perfect circles and squares. For example, you can hold down Shift (and
sometimes Ctrl) while creating objects to constrain them, as Figure 10-4 illustrates.
Figure 10-4 When you create or size objects, hold down Shift to constrain them.
The key you use to constrain your object depends on the type of constraint you want to
cause. The following lists describe the types of constraints created using each method.
Holding down the Shift key causes the following constraints:
The Line and Arrow tools draw perfectly horizontal or vertical lines or diagonal lines
constrained to exact 15-degree increments (0°, 15°, 30°, 45°, 90°, and so on).
The Rectangle tool draws perfect squares.
The Oval tool draws perfect circles.
Other shapes are drawn to predeined, roughly symmetrical constraints. Shapes come
in many different forms, so the effect of the Shift key varies considerably depending
on the shape.
Holding down the Ctrl key causes the following constraints:
When you drag to create rectangles, ovals, text boxes, and AutoShapes, the object is
centered on the point at which you click. Objects grow out from the center point as
you drag.
