The program offers several options to create construction lines, divide distances evenly, or measure distances. These lines are created on their own level (default is PS_CONST), so that all of them can be jointly hidden or deleted.

To create construction lines, you have the following options:

• Complete the fields on the Construction Lines dialog box then place lines using the command buttons at the bottom of the dialog.
• Use the various Construction Lines toolbar buttons, or type the corresponding commands as described below.

The construction lines are created only within the current user coordinate system plane.
