Here's a meme I created related to our troubles:
I think it sums it up quite nicely.
I guess you have to admire his zeal. I would be afraid, had he a pitchfork to accompany his torch. (Or maybe a Q-Tip if I am mistaken...)
Our architectural friends have come to the realization that they must lower their ceilings in a couple of major rooms to accommodate the existence of our obtrusive equipment. It is easy enough to change these few rooms, but while investigating, I found that they had changed many other ceilings (mostly heights, but a couple types as well). Now we have a coordination issue or two, but I don't know if that would have been caught had they not changed the major ceilings. I'd like to think it would've been, but if the ceilings were Copy/Monitored...
...I see what you did there. Let's bump this thread some more. Get it to the top again.
I assume your light fixture families are face-based?
If hosting to a ceiling, they are probably just hosting to the top face of the ceiling, instead of the bottom. This seems to be common with Generic Ceilings. To flip the fixture, click on the 'Flip Work Plane' icon that appears when the element is selected.
If hosting to a Reference Plane, the direction in which the Reference Plane is drawn (L to R, R to L) determines which side the fixtures will be on. You will want to draw it RIGHT to LEFT in order to get fixture to mount on the bottom of the plane.
Just a humble bump.
We need this. Desperately. It would make our lives so much cleaner us MEP consultants that do the bulk of the lighting design for a project (we pick the luminaires, do the calcs, and visualizations).
Having to create a rendering model and not being coordinated with the Architect is a real pain.
If we could copy-monitor ceilings (and the Architect in turn monitors our copied ceiling against their original one) we could truly coordinate bi-directionally.
So if we host to the copy-monitored ceiling and cut into it, the Architect is prompted the next time they reload their model that the ceiling has been cut (sketch is missing, I believe is the warning), and they can in turn cut their ceiling thus revealing our fixtures.
I can't think of a reason why this hasn't been implemented, when I can copy monitor floors and walls why can I not copy-monitor ceilings?
I would love a real reason why this functionality has remained absent for 3 version cycles. Are the mechanics involved with implementing it exteremly difficult? Is it because ceilings can be sloped? What gives?
It just drives me nuts.
Yes, we have had problems with this too, lights become un hosted when we update a linked model from architect and he has moved his ceilings.
Also looking at the 2d plan you cannot tell so our engineers are missing them.
If ceilings were copy monitored this would sort this problem easy.
