11.39. Insert Polylines

This utility allows one to insert the references of the polylines entered in the cross-section file selected. The Definition of Blocks command may subsequently be used to graphically represent this reference at its position with regard to the profiles.

The steps needed to execute the command are detailed below:

· The program requests the cross-section file on which the operation will be performed.

· The horizontal alignment from which the cross-sections have been obtained is entered.

· The polylines to be projected onto the profile are selected. These should be 3D polylines. They will be assigned the “POL” code when inserted in the profile. These should be within the area of occupation or the strip width of each profile.

· Lastly, the file in which the new cross-section file’s data will be stored is requested.
