When I run the Component Quantities command, some components report a Volume, Total Cost/Material, and Total Estimated Cost of "NaN'.
It was determined that this could happen with some overlay/stripping components that contain segments that are vertical. In this particular dataset, the overlay/stripping components had two points that were at a zero horizontal and vertical offset.
This issue is marked as fixed in the next version released after 08.11.09.493. The workaround until then is to make sure there are no true vertical segments in any components that report a volume of "NaN".
