In-Depth Information
In the same manner, any modifications to the fundamental objects that make
up a parcel will result in an automatic update to the parcel itself. This is most
evident when parcels are labeled with area, bearing, and distance information.
understanding Sites
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 inter-
acting by placing them in different sites. The sites are listed in Prospector, and
you can create as many as you need in a given drawing (see Figure 12.2).

Sites listed

one site expanded
When parcel segments are placed in the same site in such a way that they
create one or more closed shapes, the closed shapes 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, the
alignment automatically subdivides the parcel 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 the alignment and parcel in separate sites. In the left
image of Figure 12.3, the alignment and parcel are in different sites and
therefore don't 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.
