Of the many labels for parcels that come with Autodesk Civil 3D 2005 there are two very interesting ones.
The first uses a block (_Wipeout_Circle) which contains a wipeout. It is a parcel label style called "Iron Pipe Node Label". When this label is used, the label places the block at the endpoints of a parcel line. The block "hides" the area beneath it. The benefit of this label is that when parcel lines are labeled with length the label displays the actual entire length of the line (not the shortened visible length).
The second interesting label for parcels, is any label style that has the "Span outside segments" set to true. This label can apply a single label with an overall length to segments that run along the outside edge of multiple parcels.
