The Problem:
I have created a zone(1) and cut a void in the ceiling. Then I created a zone(2) by snapping to the corners of the void opening. So now zone(2) is completely covering the void cut from zone(1). But when I run a daylight factor calculation you would think no light can get through to the floor because another zone is blocking the void, but it does and the daylight factor is just as high as if the zone filling the void was not there.
Is there a way to cut a void in something and then build something on top of the void with out light getting through??
Second Problem related to the first...
I have a ceiling with a void cut into it and I want to build a roof monitor over the top of the void, but light keeps passing my monitor onto the floor as though only the void were there.
Thanks for the help

re: stop light from passing through void in ceiling
Hi Aaron -
This seems to be a problem with Ecotect's "simplified" daylight modeler. Running it exporting to Radiance seems to give more believable results.
I have a model that seems to do what you want to do. Voids in planes, boxing out a light well, etc. However, one key difference seems to be that I didn't create valid thermal zones (floors, walls, and ceiling) in the model. Because I was testing multiple configurations of ceilings and light wells, each is on a separate layer from other elements of the room (walls, floors). Again, though, this was done with Radiance as the daylight engine.
If you're just using Ecotect, I wonder if you really need to use a void. I have had similarly frustrating but essentially different struggles with the void in Ecotect - like them moving around my model for no apparent reason. If you're only doing daylight studies, and you are able to jettison the fully formed zones, perhaps you could replace the ceiling and void with multiple (at least 2) ceiling planes that block light where you want to.
