Placing objects within the same site is how you tell Civil 3D that you want these objects to “see” each other and interact. You can also prevent objects from interacting by placing them in different sites. The sites are listed in Prospector, and you can create as many as you need within a given drawing
(see Figure 12.2).

When parcel segments are placed in the same site in such a way that they create one or more closed shapes, the closed shapes will automatically become parcels. Alignments, feature lines, grading groups, and survey figures can also occupy sites. These objects are able to interact with parcels and with one another. For example, if an alignment crosses through a parcel, it will automatically subdivide it to create two parcels. For this to take place, the parcel and the alignment must be in the same site. By the same token, you can prevent the alignment from subdividing the parcel by placing it in a different site. In the left image of
Figure 12.3, the alignment and parcel are in different sites and therefore do not interact to create two parcels from one. In the right image of
Figure 12.3, the alignment has been moved to the same site as the parcel, causing it to be subdivided automatically.
