Inserting calculation surfaces into Exterior Scene Floor flan

[Bushair]

Hello,
I am grateful for the answers I have obtained to the questions I posted earlier on this forum. I have another query as follows:
I am trying to insert a calculation surface called 'Escape Route' into Exterior Scene Floor plan but I am unable to do. I can neither drag and drop the calculation surface (which is the short cut method), nor can I manually press the Insert button in the Geometry. The errors shown in the attached snapshots pop-up. Please explain to me how do I fix this problem.

Hello Bushair,

Emergency lighting is not defined in the standard for an exterior scene. Therefore, it is only possible to use the calculation area of an escape route for indoor projects. Unfortunately, we do not have a workaround that we can offer you.
