seems like that both linear and area light are not fully implemented yet.
Although I believe that, as far as I know Vectorworks INC. this is a problem by Vectorworks itself.
So that data from the Vectorworks API is not being transported to the Enscape Engine completely/correctly.
Furthermore, i fear that cuz Vec inc. is often releasing features half build, completing them pretty slowly, this will take for sure a while to work like in SketchUp :(.
your case worked for me .... but it seems still buggy (example attached)
Here some other stuff i noticed already:
Linear Light is not working if there are:
+ More than 2 corners
+ round corners
+ Start and Endpoint longer than around 4 meters apart
the Lumen Entry in Vectorworks is not getting transported to Enscape.
--> use Brightness Entry instead(in German Dimmer oder Helligkeit)
