Constraining a basic shape as you draw
You can constrain how a tool draws a basic shape. When constrained, the Rectangle tool draws a square, the Ellipse tool draws a circle, and the Line tool draws at increments of 45° .
You can change the constrain angle. When the constrain angle is 0° , holding down the Shift key constrains objects to 0° , 45° , 90° , and so on. Changing the constrain angle shifts these angles by the specified amount. A constrain angle of 10° , for example, changes the angles to 10° , 55° , 100° , and so on. If you change the constrain angle, when you draw a rectangle, line, or ellipse it will be tilted to the value you specified.
To constrain a shape as you draw, do one of the following:
![]() |
To constrain a shape, hold down Shift as you drag the pointer. |
![]() |
To constrain a shape as you draw from the center, hold down Alt (Windows) or Option (Macintosh) and Shift-drag the pointer. |
To set the constrain angle:
1 |
Choose Modify > Constrain. |
2 |
Enter a value in the Angle text box, or use the wheel to set the angle. |
3 |
Click OK. |
