Autodesk Revit Architecture

[#1]

I did a search for this subject. People have asked the question but there was no answer.

Is there a setting to export the grid lines of ACT ceiling in a 3D view to DWG?

I don't know if there is because I can't even get the grid lines to show in a 3d view. Right now the view shows the ACT celiling as a simple geometric shape. I guess that is a pretty strong statement coming from a newb user. So I need your help!

Yes - you can export ATC ceiling with their respective gridlines.

I have posted 2 views - one that is revit and the other what it looks like in AutoCAD.

This functionality has been there a long time.

I am concerned with the grid and tiles in a 3d view. Not 2d.

[#4]

Any more ideas or solutions about this? I haven't found a satisfactory one yet. It is an important issue with coordinating with engineering consultants - that they can see our ceiling grid locations and also have the correct ceiling heights in 3D.

I have heard of using sloped glazing to create a type of "ceiling grid". Or to use "pick lines" and draw lines over top of all the ceiling grid. Both of those options create a lot more work for the architecture team. Or, We could do 2D export showing the grid, and a 3D export showing the ceiling heights. That creates a lot more work for the MEP team linking in the files.

Has anyone come up with something clever to do here?

So how did you do this before using Revit? were you using another 3D program?

what software are the MEP using? AutoCAD MEP? how did they do this before?

Using the curtain wall to get in the ceiling lines would be your best bet.

But if they just need to know a ceiling height - can't an elevation give them that info? of a ceiling plan that has the ceciling heights listed? do they want the gridlines to place their ceiling mounted components?

help us understand the workflow and the final outcome you are looking for. It may be that Revit just can't do what exactly you want.

Follow up:

You CAN"T make the ceiling grid be apart of the 3D model. Which I understand now. The reason, my guess, each grid piece would need to have it's own family. Then the same for the tiles. (Get on that Armstrong!) Creating all of that extra modeling math... I don't think it's "Revits" intention to start modeling ceiling grid and individual tiles. I believe, they believe, modeling a hole in the ceiling geometry of where they would like lights and diffusers is efficient enough for MEP to place their equipment.

It turns out, the MEP trades only wanted a 2D of it. As a majority of them are still using AutoCAD. So I exported the reflected ceiling plan along with the 3D view. Everybody happy.

What do you think? Should Revit model each piece of a ACT ceiling? I don't see the benefit right now.

Interesting question.

I find it a bit amusing that we "accept" things like curtainwalls having 3D mullions and glass panels with real thickness and even properties of the glass; and we readily populate our models with them, which takes enormous computer resources.

But then on a simple ACT ceiling, we "accept" it being only a half-baked 3D representation.

Why is it "OK" to have fully modeled curtainwalls, but "Not OK" to have fully modeled ACT ceilings?

A Virtual Model should be just that--a true 3D representation of the real built project. 

We should "accept" real 3D ceilings with each grid and panel, just like we do curtainwalls, railings, stairs, and lots of other complex assemblies. I wonder why the programmers of Revit (prior to Autodesk's aquisition) chose NOT to make ceilings truly 3D?

I'm a flip-flopper! I'm with Cliff! 

This is why I brought up the question. I thought I just had a visibility setting turned off. I figured, like Cliff pointed out, why wouldn't it model the grid?

Modeling of the grid ACT & Drywall would be AWESOME! Don't forget the hanger wires.... 

Get on it Autodesk!

The though of over modeling comes to mind...

A curtainwall is something very specific and completely customizable. an ACT ceiling... pretty well set on size and everything else related to it. I do not see a reason to have all of the indivudal panels of a ceiling avaiable. 

If you want each indivudal panel... you could make each panel its own ceiling....

Again this is just my opnion...

Lisa,

OK--then how about a "standard" railing? Yes, it's customizable--but in a simple egress stairway for instance, 99% of the time it will be "standard". So--why is it "OK" to model all of the posts, rails, and balusters? This is very resource intensive,

so the argument for "over modeling" comes to mind here as well. It's just odd to me that Ceilings get treated differently than

other systems like curtainwalls, railings, stairs, etc. These could also be "faked" with a more 2D representation, but for some reason they are not.

I'd vote for "real 3D ceilings"--just like "real 3D railings and curtainwalls."

Food for thought.
