Bounded and Unbounded Lines
By default, a Measured Line is created as bounded (BND form of the FEAT/LINE statement). You can define it as unbounded (UNBND form of the FEAT/LINE statement) by using the Specify Unbnd option in the PTS AND PATH menu (this option appears for Measure Line steps only).
When you select Specify Unbnd, the LINE BND/UNB menu appears with the following options:
• Specify—Select the direction in which the line is unbounded, by using Flip and Okay options.
• Remove—Lets you revert to the bounded form of line output. Available only if the line is currently defined as unbounded.
