These tutorials will get you started working with junctions.
A junction object is created from two intersecting alignments that have design profiles. During the junction creation process, alignments and profiles are automatically generated for the offset and radius kerb geometry. The horizontal and vertical geometry of the offsets and radius kerbs is dynamically linked to the junction object. When changes are made to the centerline alignments or profiles, the offset and radius kerb geometry is automatically updated.
All drawings used in these tutorials are available in the tutorials drawings folder. If you want to save your work from these tutorials, save the drawings to the My Tutorial Data folder so that you do not overwrite the original drawings.
