Ceiling Modelling Best Practice

[Mohamed-Nassar]

What about this Idea to add Ceiling to Copy/Monitor Elements, can you provide your answer with explain why?

i think this idea will provide a support to MEP Disciplines!

Definitely yes especially Grind alignment and Level changes.

Are there another ideas to this flow because we now can't Copy/Monitor Ceiling.

though i'm pretty sure this has been requested in the past... this sounds like i good post for the Ideas Forum.

MEP can host to ceiling through a link. No need to copy.

it is great that we can host our recessed lights to the Arch ceiling thru a link, but it doesn't cut the lines like it would if the ceiling was in the model. 

The light on the left is a light placed in the electrical model hosted to the face of the architectural ceiling. the light on the Right is same light family loaded in the Architectural link. my engineers have been complaining about this for years. we have tried all sorts of things to work around it, but it would be nice if it jsut cut the Architecturla ceiling or we could copy/monitor the architectural ceiling.

Even in my AutoCAD days, we didn't show ceiling grids. The architect determines the location of ceiling fixtures and our drawings note to refer to architect's drawings for final locations. We used to show grids but then chasing them around as they were adjusted was a total waste time and our drawings would be wrong if we got a last minute update that included grid shifts that we were not notified of.

It's kind of a heated topic to some but very relevant unless MEP is doing RCP coordination and showing true RCPs on our drawings. Typically, MEP drawings that have a ceiling grid are floor plans, not true RCPs which, BTW, should only show ceiling objects. Haven't you ever wondered why you can't just turn on the ceiling grids in floor plans?

i agree, At my current firm, my Mechanical engineers work the way you mention. The Electrical engineers use the Reflected Ceiling Plan views and want to show the ceiling grid in there RCP views when placing lights and other ceiling devices.

My philosophy has always been consistency between trades. The argument with the electrical guys has been a tough one at times and somewhat understandable from their perspective but not totally. I always fall back on the "true RCP" point. It's a ceiling plan. For electrical that would mean no wall fixtures, no switches, etc. If they want to see that stuff, with their lights use a floor plan. If they want to see the ceiling grid, don't show anything that is not on the ceiling. That strict definition of an RCP has been lost for some and some even have trouble conceiving of such a thing.

Thanks Mr.Rob for your interest

it's impossible to see the RCP elements in floor plan we have RCP plan to host the elements which it will appear in the RCP plans to make the real digital model be fore construction for many reasons like coordination..etc

BTW we have modeled the elements with standards drawings which elements need to host ceiling in RCP plans and switches to host walls in floor plan to see real building before construction and avoid any clash before construction process.

Ceiling hosted elements can be seen in floor plan views. I've done it in every project I've ever worked on. You're going to have to rethink that one.

That's right for the point of Revit viewing but why i don't need this in drawings i need to see only ceiling grids and Revit allow me to put my lighting fixtures on ceiling so i make it real to see the elements where it will installation to make a better coordination and align electrical fixture with Ceiling grid cause we have also a Air terminals

I don't understand the question.
