Setting a scale factor
You can create a document using a scale factor so all measurements are scaled when they are shown on the screen. For example, if you create a document on a page which is 21cm across and use a scale factor of 1:100 (1 centimeter on the page is shown as a meter) the measurements you see on the Status Line and Selector Tool Infobar will range from 0 to 2100cm. Using a scale factor is ideal for drawing scaled drawing like maps.
To set a scale factor
1. From the Utilities Menu, choose Options.
2. Click the Scaling tab.
3. Click the Use Scale Factor option.
4. Enter the scaling values.
