Additional Exercise

Having completed this section, you should now have a better understanding and appreciation for the power of the relationships upon which Civil 3D is built. You have seen how styles relate to objects, objects relate to other objects, and labels relate to the things they annotate. These relationships take the repetition out of design work that used to plague it before Civil 3D was available. You are fortunate to be performing design with such powerful tools that enable you to focus more on applying your creativity and ingenuity than on performing repetitious tasks such as editing labels or fixing minor design discrepancies. From a designer’s perspective, the relationships in Civil 3D simply make design more fun. From a business perspective, the relationships in Civil 3D make design more profitable.

For these exercises, open the drawing named Parcels.dwg or (Parcels.dwg (METRIC)) located in the Exercise_02 class data folder.
Then use the objects, labels, and styles within it to study the relationships that exist in a typical residential-subdivision design. Specifically, investigate the following:

1. Change the style applied to one or more parcels to display them as open space rather than single-family.
2. Change the style assigned to one or more parcel area labels to display more than just the parcel number.
3. Use grip editing to change the geometry of the road centerline, and observe what happens to the geometry of the parcels. Consider the relationships that make this behavior possible.
4. Use grip editing to move several parcel lines that are perpendicular to the road. Observe how the adjacent parcels and their labels respond. Consider the relationships that make this behavior possible.
5. Create a data reference to the Existing Ground surface using the data shortcut created in the previous exercise. Then create a profile of this surface along the Main Road A alignment.
