Exercise 3: Editing the Grading Criteria

In this exercise, you will edit a grading criteria and an associated grading adjusts to reflect the criteria change.

You will edit grading criteria attribute values in two ways:

• In the Elevation Editor dialog box. Using this method updates the grading criteria for only the currently selected grading object.
• Directly in the Grading Criteria settings. Using this method will apply the attribute changes to future grading objects created with the criteria. If the attribute value is locked, attribute changes will also be applied to grading objects that currently use the criteria.

This exercise continues from Exercise 2: Balancing Cut and Fill Volumes.

This exercise uses the drawing Grading-3A.dwg, which contains two grading groups that use the same grading criteria.

Edit the grading criteria

1. Open Grading-3A.dwg, which is located in the tutorials drawings folder.
2. Click Modify tab Design panel Grading .
3. Click Grading tab Modify panel Grading Editor Find.
4. Click inside the grading that projects from feature line AB.
5. In the Grading Editor Panorama, change the distance value to 5.0000.

   Notice that grading AB updates to reflect the change. Now, you will make a similar change that will affect all grading groups using the Distance @ -6% grading criteria.

6. In Toolspace, on the Settings tab, expand GradingGrading Criteria SetsDitch Criteria Set.
7. Right-click Distance @ -6%. Click Edit.
8. In the Grading Criteria dialog box, click the Criteria tab. Change the Distance parameter to 20 and click . This locks the attribute value, which will apply it to all grading objects that currently use the Distance @ -6% grading criteria. Leaving the value unlocked applies the value to only grading objects that are created in the future.
9. Click OK.

   The AB and BC grading objects are both updated in the drawing to account for the new criteria value.
