This exercise continues from Exercise 2: Viewing and Correcting Alignment Design Criteria Violations (page 253). Create an alignment design check 1 Open Align-7C.dwg, which is located in the tutorial drawings folder (page 819). 2 In Toolspace, on the Settings tab, expand the Alignment ➤ Design 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. 3 Right-click the Line collection. Click New. 4 In the New Design Check dialog box, for Name, enter L>=310m @ 50km/h. BEST PRACTICE Because design check tooltips do not display specific values, a design check name should be specific and unique. Use the mathematical formula or other specific information to simplify the process of correcting a design check violation. 5 For Description, enter Tangent length must be >= 310m if design speed is >= 50km/h. 6 Click Insert Function. Click IF. The IF function is displayed in the Design Check field. 7 Click Insert Property. Select Design Speed. 8 In the Design Check field, use the keypad to enter >=50, (including the comma) after the {Design Speed} property. Exercise 3: Working with Design Checks | 257
