819).
2 In Toolspace, on the Settings tab, expand the Alignment
Checks collection.
Notice that five collections are available. The Design Check Sets collection
contains combinations of design checks. A design check must be added
to a design check set before it can be applied to an alignment.
The other four collections contain the design checks for each type of
alignment entity. Each entity type has specific properties that can be
checked. When you create a design check set, you specify the type of
entity you want to check, and then the specific design check you want
to apply to that entity. You can apply multiple design checks to each
entity type.
NOTE The Tangent Intersection collection contains design checks for spiral
and curve groups.
