I am stuck in getting a lighting fixture family to not bring in it’s light source sub category into rhino. Is there a way in which this subcategory can be filtered out? Thanks in advance for any tips on getting me into the right direction.
Hi @Japhy,
I’m just coming across this 4 years later and shocked that there doesn’t seem to be a differentiation between the light source and the geometry of the family/fixture itself.
What’s puzzling to me is that I do see a append distinction as “|Light Source” within the Element Category list itself but this seems to be completely disconnected from the reality of what is a light source and what is not…
Strangely, in further explorations, when I explode the Revit Component and peak the Model Object Layer names I actually DO get the proper light source isolated and am able to cull the data/geometry using this approach… However, exploding hundreds or thousands of light fixture families in a typical commercial project this would be a long computation just to peak some metadata.
Is this a bug that the Model Object Layer data is correct but that the Revit category is incorrect or one of those weird Revit API/limitation things?
My example/workaround:
EDIT:
Interestingly, the Layer names are correct AND there is even a Hidden property that can be used to cull the light source itself…
That is correct yes, I am interested in retaining the Family Geometry but culling and/or replacing the “light source” with a Rhino light source, Enscape, D5, etc.
Assuming that you are in a large project there could be a variety of conditions due to various Revit Family builders that people downloaded into their revit project.
Yes, this single “view” I’m working with has 400+ light fixtures in it. Some recessed downlights, some surface mounted downlights, pendants, etc.
What I am doing as an optimization to handle it is I create a set of the unique components:
This allows me to modify only 25 unique light fixtures here and then I can propagate any changes back to the full 400+ instances throughout.
could be a variety of conditions
Yes, I do expect there to be but I think a Revit “light source” is a consistent Revit Object regardless of how it was created and if I recall correctly a lighting family in Revit always has a light source, you actually can’t remove it, you can only make a Generic family or other family that doesn’t come with a lightsource.
This is all I see in the Revit API:
