180310: Cannot generate floor transitions. No expression defined for either stairway_unit_exp or elevator_unit_exp parameters. At least one entry must be provided.

Description

To generate transition features, the tool must identify which units on each level represent spaces where a person can transition from one floor to another. The tool identifies these spaces using SQL expressions you provide.

  • The stairway unit expression identifies stairways.
  • The elevator unit expression identifies elevators.

You can provide one or both of these expressions. If neither is provided, the tool fails.

Solution

Ensure that you have supplied the tool with a stairway unit expression, an elevator unit expression, or both, and that the expression syntax is correct. Contact Esri technical support for more information.
