Kevin,
Autodesk Civil 3D has a dynamic topology model which is used for analysis of
parcel and alignment linework in the design. When you created the
objects, you do need to specific a "Site" for the objects. The parcel and
alignment creation dialogs have a control which allows you to select the
specific Site. It looks like we did not provide a setting for the "default"
site when you run those commands. That is a good suggestion.
If the objects are in different Sites, then there will be no interaction of
parcels, alignments, and feature lines between Sites. In Autodesk Civil 3D
2006, there is a new feature which allows the users to move the objects
between Sites.
If the alignments or parcels form a closed shape, it will create a "parcel"
in that Site. Therefore, in this example, if the Alignment forms a closed
loop, it will create a parcel in the same site which contains the alignment.
The same behavior happens when parcel segments form a closed loop. The
parcel which is created cannot be "deleted" since there is a topological
relationship between the parcel segment lines (and alignments) and the
closed area. The best solution is to hide the label. You can do this by
either 1) defining a parcel label style which has a layer defined in the
label style and then using Layer control for visibility, or 2) Creating a
label style with the visibility set to "False". We could also expose that
style in the Alignment command settings so that you could set the style
before running the command. If we made that setting available, you could
set it up so that you would never see those labels.

Is there anyway to STOP c3d from automatically creating parcels if my
alignments form a closed area? Once one has already been created, is there
any way of deleting it without deleting an alignment?
