The video below demonstrates how the PerpCheck
command may be used to analyze and fix Parcels in Autodesk Civil 3D. The PerpCheck command can mark intersections
that are radial/perpendicular, intersections that are not radial/perpendicular,
and find "gaps" in the linework where Parcels are failing to close properly.
The tasks illustrated in this demonstration require the Drafting Module of the Sincpac
C3D, and may be performed in Civil 3D 2008 and later.
