Specifying a Measurement of an Object
In the following examples, we specify the angle of a triangle and the length of one side of a
triangle.
u To specify the angle of a triangle
1. Draw a triangle.
2. Select side AC and then select side BC.
3. Press J to display the measurement box.
• This displays the size of ∠ ACB (in degrees) in the measurement box.
4. Input the value you want to specify for ∠ ACB (in degrees) into the measurement box and
then press w.
• In this example we input 90, which makes ∠ ACB 90 degrees.
5. To close the measurement box, press J twice.
Note
• Performing step 5 in the above procedure not only changes the measurement value, it
also locks the measurement. For details about locking and unlocking measurements, see
"Locking or Unlocking the Measurements of an Object" (page 5-9).
• Specifying a value can change an object in a way that is unexpected. If this happens, try
locking part(s) of the object (page 5-10) or temporarily unlock all objects (Clr Constraint,
page 5-11).
