Place fixtures on ceilings.. 30 feet off?


why are the lighting fixtures placed many feet above the ceiling?

The blue preview of the points appears correct, that is, on the bottom face of the ceiling, which was the face selected for the script.

“FamilyIstance.ByPoint” also does not work properly…

Also, if i had to select the whole ceiling element, how do I extract geometry information from it?

thank you


Is there a default offset if you attempt to place a fixture using the UI?


even changing the default elevation does not seem to do anything much.

How are ceiling based fixtures be able to be created floating in mid air? I guess it is one of many Dynamo extra powers… Like the ability to create different types with the same name… freaky.

Can you provide a new Revit file and the DYN to look into?
