This option is used to draw a grade line without the need for the longitudinal or the corresponding segment.
The functioning of the command is similar to the Draw Simple Profile and Draw Compound Profile commands in the Longitudinal options and allows us, from the grade line file selection, to draw it with the associated numerical data elements.
By default, the compound numerical data is associated (see configuration > Profiles) and only those elements that are related to the grade line to be represented are drawn.
