Key Concepts

■

In addition to the finished ground profile, you can design ditches

and transitions in profile view.

■

You can use the Create Tangents commands on the Profile menu,

or the AutoCAD LINE command to draw vertical tangents, but you

must use the Vertical Curves commands to draw vertical curves.

■

Other useful tools for drafting vertical tangents are available from

the Profiles

➤

FG Centerline Tangents menu.

■

In order to properly define the finished ground profiles, you must

draw them on the correct layer. Before drawing any entities, set the

current layer with the Set Current Layer command.

■

After you design finished ground elements in profile view for

transition control and ditches, you can “attach” them to the cross

sections, automatically updating the templates with the ditch and

transition elevations you established in profile view.
