Constrain Angle, Aspect Ratio and Location

Use constraints to keep lines perpendicular or at set angles to the page,and to control the relative horizontal and vertical size of an object – its “aspect ratio”.

Constrain Position While Moving

  1. Choose the Select [s] tool and select an object.
  2. Press the SHIFT key while dragging the object. This constrains the object angle to 45° alignments of its original position

Constrain Rotation Angle

  1. Choose the Select [s] tool and select an object.
  2. Press the SHIFT key while dragging the object’s purple Rotation handle to rotate. This constrains the object angle to 15-degree increments

Constrain the Angle of a Line

  1. Choose the Irregular Polygon or Line [l] tool.
  2. Press the SHIFT key while drawing. This constrains the line angle to 15-degree increments

Constrain Aspect Ratio While Drawing Circles and Squares

  1. Choose the Rectangle [r] tool, Oval [o] tool, or Round Rectangle tool.
  2. While drawing the shape, press the SHIFT key to constrain its aspect ratio, resulting in a perfect square, circle or rounded square.

HINT: The SHIFT key can be used in combination with the COMMAND key to constrain the aspect ratio and draw out from center.

Constrain Aspect Ratio While Resizing

Do one of the following:

  1. Choose the Select [s] tool and select an object, press the SHIFT key to constrain its aspect ratio, and drag the object handles to resize an object or group,
  2. With the object selected, click the Lock icon in the Geometry panel to lock the width / height aspect ratio, then enter the object width or height in the Geometry Tab.

Resize Out from Center

  1. Choose the Select [s] tool and select the shape (or group) to resize.
  2. Hold the OPTION key, then press and drag the object (or group) handles to resize while constraining the location of the object center point.
