Revit Based HydraCAD (Ribbon/Toolbar/Location)

Button: Spacing and Layout Function: Pick ...

Description:

When trying to select Pick Light, this error shows... Sequence contains no elements


Solutions:

Cause:

The Revit 2026 update caused an issue with classifying lights in HydraCAD for Revit

Solution:

Watch for an update, and update to version 26.2.008 or higher when it is available.


In the meantime, to successfully use the Spacing and Layout tool, use the Pick 3 Points selection method instead.
