To Change the Constraint Type of Free Vertical Curves from Pass Through to Length

You can convert free vertical curves (created with the Free Vertical Curve (Circular) command or the Free Vertical Curve (Parabola) command) which use a pass through point as their constraint type to curves that use length as their constraint type. This command converts the constraint type of all relevant curves at once.

Important: This command is intended to provide backward-compatibility with previous versions of the application (version 2014 and earlier). Free vertical curves created with the Free Vertical Curve (Circular) command or the Free Vertical Curve (Parabola) that use a pass through point must be converted to a format that is recognizable in these previous versions of the application. If you do not convert the curves, the curves will be missing when the drawing is opened in previous versions of the application.

Note: This command does not convert PVI-based free vertical curves that are defined by pass-through point.
