The Options - Scale Text command is used to modify the size of the on-screen text so the text can be more easily viewed. Selecting the Options - Scale Text command will cause the Set Text Scale dialog box to appear.

When showing text on the screen, a default text scale factor of 1 is assigned. In some instances, this scale factor may not be ideal for the given model. You can increase the text scale by making the scale factor larger or decrease it by making the scale factor smaller.

Click the OK button for the new scale factor to take effect.

There are also two additional buttons on the toolbar that affect the text size. The Increase Text Size button incrementally increases the text size each time it is invoked, and the Decrease Text Size button likewise incrementally decreases the text size.
