u To specify the length of one side of a triangle
Note
• Specifying any one of the following measurements for the fi rst time in the fi le you are
editing (or immediately after an all clear operation: 2(Edit) – 6:Clear All) will cause the
resulting object to be resized so it fi ts within the display area.
- Length of one side of a triangle
- Length of a line segment or vector
- Length of one side of a rectangle, square, polygon, or regular n-gon
- Circumference of a circle or length of an arc
View Window settings will be reconfi gured automatically so the size of the object on the
display may not appear to change very much.
The following example shows what happens when the length of the base of a triangle
drawn with default View Window settings (with a screen width of 10.7) is changed to 120.
View Window settings are reconfi gured in order to ensure that specifying a measurement
of an object does not make it too bit to fi t on the screen or too small to see. Note that all
other objects currently on the screen also will be resized by the same amount at the object
whose measurement you are specifying.
• Once you specify one measurement of an object, it will not be resized further if you specify
another of its measurements.
• In the following example, the length of the same side of a triangle will be specifi ed twice.
Note the difference between what happens when you specify the fi rst measurement and
when you specify the second measurement.
1. Perform the following operation to clear the screen: 2(Edit) – 6:Clear All.
2. Perform the following operation to display the View Window screen: !3(V-WIN).
3. Press 1(INIT) to initialize View Window settings.
4. Press J to exit the View Window screen.
