240020: LVEShapes geometry will be generated using straight lines for GTFS dataset <value>.
Description
The tool could not generate geometry for the public transit data model's LVEShapes feature class from the GTFS shapes.txt file, so it will instead populate the LVEShapes feature class's geometry with straight lines matching the geometry of the LineVariantElements feature class.
Solution
Refer to the other tool messages for the specific reason that geometry could not be generated. Either correct the errors in the data, use a different GTFS dataset, or accept the straight-line geometry.
