Create design checks to verify the design parameters for criteria that are not included in the design criteria tables.
The tables contained in the design criteria file contain A.A.S.H.T.O. standards tables for Stopping Sight Distance, Passing Sight Distance, and Headlight Sight Distance minimum K values at specified design speeds. Other criteria can be checked by using mathematical expressions, which are known as design checks .
Design checks are created and managed in the same manner as label expressions. Use the Design Check Editor dialog box, which is similar to the Expressions dialog box, to create and edit design checks. To apply a design check to a profile, you must add it to a design check set .
Design checks differ from label expressions in that they always return a true or false value. For example, you can create a design check to issue a notification if a tangent is shorter than a specified minimum tangent length.
