Using the Measurement Box

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.
