Applying Design Check Sets

A design check set is a collection of one or more design checks. There are four types of design checks: line, curve, spiral, and tangent intersection. When a design check set is applied to an alignment, Civil 3D will flag any violations with a triangular yellow shield marked with an exclamation point. You can hover over the shield to get more information about the violation, as shown in Figure 5.15.

To apply a design check set to an alignment and edit the alignment based on what it reports, follow these steps:

1. Open the drawing named Design Check Set.dwg located in the Chapter 05 class data folder.

2. Click the Jordan Court alignment, and then click Alignment Properties on the ribbon.
3. In the Alignment Properties dialog box, click the Design Criteria tab.
4. Change the Design Speed value to 25 (40).
5. Check the box next to Use criteria-based design.
6. Uncheck the box next to Use design criteria file.
7. Verify that Use Design Check Set is checked and select Subdivision.
8. Click OK to close the Alignment Properties dialog box. Press Esc to clear the grips on the alignment. You should see three yellow warning symbols in the drawing, as shown in Figure 5.16.

9. Zoom in to the curve farthest to the south. Hover your cursor over the yellow shield. A tooltip should appear, indicating that the Subdivision Curve design check has been violated.

   Tips :If no tooltip appears, type rollovertips at the command line; then type 1 and press Enter.

10. Use grips to increase the radius of the curve until the shield disappears.

11. Click the Jordan Court alignment, and then click Geometry Editor on the ribbon.

12. On the Alignment Layout Tools toolbar, click Alignment Grid View. Notice the yellow shields in the No. column as well as the bold values in the Radius column and several other columns (see Figure 5.5.17). This tells you which items have violations as well as which specific values are causing them.

13. Change the radius of item 3 to 150 (45). The shield disappears, and the bold values for item 3 now show in normal print. The curve at item 5 will remain set to a 50' (15m) radius.
