Autodesk introduced a bug in Revit 2017 which can cause the project Phase information to become corrupted when using the Wire command.  This manifests in all Phases being removed from the project, without the possibility to recover them or add new ones.  

ElumTools expects all projects to have at least one Phase, and will not function properly once this problem occurs.  Similarly, this issue also causes problems in many other parts of Revit.


Calculate Boundary (rooms, spaces, areas, regions) commands do not parse host model geometry correctly when project Phase information is corrupt.  If Filter by View Visibility is set to true, the user gets the error shown below.  If Filter by View Visibility is set to false, the calculation will run but ElumTools will fail to detect any elements residing in the host model.  This usually results in a black rendering since the luminaires must reside in the host model.

Applies to Revit 2017 and 2018.


Autodesk has released patches that address the problem.  Users should update to the following Revit versions or greater, as appropriate.

  • 2018.1
  • 2017.2.3


Because this problem only affects the calculate boundary commands, users can still use the Calculate View commands or Calculate Selected Element command on projects experiencing this problem.
