Changing font scale

You can select the font scale so that the font size either changes or stays unchanged as you zoom in and out on a plan.

Choose View > Appearance ().
Select the appearance scheme (if a plan or perspective is the active window, the selection is already the scheme set for that window).
Enter the font scale and click OK.

Note: A font scale of zero causes the font to stay a constant size regardless of the plan scale. A non-zero value scales the font to be the same relative size as you zoom in and out
