Exercise 3: Applying a Mask to an Alignment

In this exercise, you will hide a portion of an alignment from view.
When you apply a mask to a portion of an alignment, the alignment
sub-entities, labels, and marker points are not drawn. These items still exist,
but are hidden from view.
This feature is useful when working on an intersection. In many cases, you
do not need to see the alignment geometry that passes through the
intersection. In this exercise, you will mask the portion of an offset alignment
that passes through an intersection.
For more information, see the AutoCAD Civil 3D Help topic Alignment
Properties.
This exercise continues from Exercise 2: Grip Editing an Alignment (page 225).
