Before beginning a form design session, it is recommended you set up your workspace to help you with form design. Tools, Options provides this facility, with Preferences tab providing access to preferred Measurement units.

Select your preferred measurement from the Measurement units list.

For fine design, we prefer 1/300th of an inch measurement.  

Folder gives access to the standard paths for Forms, Pictures and Logos and Data files where you are populating your OMR forms with data.

Custom masks provide for setup and maintenance of any standard masks, used for incoming data presentation, and are discussed in that section, see Custom Masking.
