    How often do you have to make an alignment, but all you have is a 3D polyline? How useful would it be to transform this line into an alignment including a surface profile?

    Step 1:

    Select the 3D line, right-click, create a quick-profile.

    Step 2:

    Using the command "LANDXMLOUT" or menu, Output, Export to LandXML.

    Now export a .xml file, by selecting the profile in your quick-profile.

    Step 3:

    Now import the .xml file and you get an alignment and a profile that shows the height of the polyline.
