Overview

Land-development projects often involve the subdivision of large pieces of land into smaller lots. Even when our projects do not directly involve subdivision, we are often required to show the legal boundaries of our site and the adjoining sites.

In previous CAD systems, we had few tools available for parcel management. We would create AutoCAD entities, such as lines and arcs, to represent the lot boundaries and then create a closed polyline to assist us in determining the parcel area. We would create static text labels for area, bearing, and distance. Even if we took advantage of some of the parcel-management tools in Land Desktop, the most minor change to the project, such as a road widening or a horizontal alignment adjustment, would require days of editing, adjustment, and relabeling.

Civil 3D parcels give us a dynamic way to create, edit, manage, and annotate these legal land divisions. If you edit a parcel segment to make a lot larger, all of the affected labels will update including areas, bearings, distances, curve information, and table information.

By the end of this chapter, you will be able to:

• Create a boundary parcel from objects

• Create a right-of-way parcel using the right-of-way tool

• Create subdivision lots automatically by layout

• Add multiple parcel segment labels

Creating and Managing Sites

In Civil 3D, a site is a collection of parcels, alignments, grading objects, and feature lines that share a common topology. In other words, Civil 3D objects that are on the same site are...
