Learn about the exhaust system design process in the Revit MEP Mechanical course, as the discussion delves into making annotations, adjusting view ranges, and creating working views. The article also explores the method of populating diffusers, tagging spaces for clarity, and adjusting the scale of your view for a better work experience.
Key Insights
- The article explains the benefits of working views in design, explaining that these views allow for scale changes, annotations, and drawing lines without impacting what's printed on the sheet.
- It guides you through adjusting view ranges to enhance visualization, tagging spaces for better identification of rooms, and populating diffusers as part of the exhaust system design.
- The article highlights the importance of mindful placement when setting up diffusers, taking into account factors such as room partitioning and the type of ceiling. It also differentiates between return, supply, and exhaust diffusers based on built-in family lines.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Welcome back to the VDCF video course content for Revit MEP Mechanical. Now, to get started with this next set of videos, I'm going to go ahead and return to my level one ceiling mechanical plan. And let's start to talk about the exhaust system that's going to be here.
Now, throughout these videos, we've kind of changed some of these working views. And the really nice thing about working views is that they don't affect what's happening on the sheet, because our sheet views actually what is on the sheet, our working view here, we can change the scale, we can make annotations, we can draw lines, we can make notes, but we're never going to affect what's actually printed. We can create the elements that we need to help us or adjust view ranges or those kind of things.
So in this particular view, you may notice that I can see the roof edges based up here, and I kind of have almost like double diffusers, which really what's happening is I'm seeing through the building because it's a reflected ceiling plane. So I'm looking back up through the building. So I'm going to go ahead as we start to work on our other systems, I'm actually going to go ahead and adjust my view range so that it looks like how I want it to be.
So I'm going to go over here to view range. And if yours is already set correctly, that's perfectly fine. But I'm going to change my view depth to just be level above and then offset of zero feet zero inches.
I'm going to hit apply. I'm gonna hit OK, you can kind of see how my view changed back here. Now I'm only seeing everything that is on the first floor overhead.

So the first system I want to go ahead and talk about is going to be our exhaust system. Now realistically, what we need to go ahead and do is obviously would be based on calculations of exactly how much exhaust we want. But we're going to go ahead and put in some diffusers.
We have our janitor rooms here. And one thing we're going to do here, it's kind of nice to do is I'm actually going to tag the spaces in this view. As I'm working, it's nice to be able to know exactly what rooms I'm looking at.
You know, I know this is a janitor, I can hover over it. But let's go ahead and create some space tags on this view. Again, this is a working view.
We don't necessarily need to put it on a sheet or anything or don't necessarily need to have it perfect. But I want to be sure that I'm look, I know what these rooms are. And these spaces are when I'm working.
So I'm going to go to annotate. I'm going to go to tag all I'm going to scroll down and find my space tags. Right there.
I'm going to go ahead hit apply. And there we go. And then I'm going to go ahead hit OK.
And that's all I need to do. Now if these tags are kind of getting in your way, again, this is a working view, right? So I'm going to change my scale, I really don't care. I'm going to change it to say like quarter of an inch, so that my symbols get a little smaller.
I can still see them, I can still read them, but they don't get in the way of me modeling. Now one thing we have to know about the bathrooms is that these are going to be a hard lid ceiling. What that means is going frame of metal studs with gyp board typically, typically there's like a high gloss finish that allows it to be cleaned easily.
The walls in here may be tile or some other kind of easy to clean surface that is appropriate for a bathroom. Same with the janitor rooms. So the diffusers don't necessarily have an exact location per se, we can dimension that location and give it a specific spot.
But we're not going to have like over here in the special ed room, we don't have these ACT grid lines, because this is going to be a gyp ceiling, or drywall ceiling. So I want to first start by populating my actual diffusers. So I'm going to go up to my systems tab, I'm going to select air terminal.
Now, you may not have exhaust grill selected, I currently do, but a quick and easy way to find it, and this is something kind of that they've started adding in, notice there's a search bar in here. So up here at the top, you know, we have a lot of different families in the course of this project. So I want to make it easy for me to search.
So I'm going to go ahead and type in I know I'm looking for an exhaust grill. So I'm just going to start typing exhaust. And notice how it starts to filter this list down based on what I type.
So I have the 24 × 24 phase with a 12 × 12 connection, I'm going to go ahead and hit OK. Now, by just looking at this, and you may not necessarily see this guy here. But by just looking at this, I can kind of tell that this is a non hosted element.
Up here at the top, it's not asking me for what kind of host face Do I want to do I want to go to a work plane, do I want to go to a vertical face. So I can kind of tell this is a non hosted element, you your elevation from level might be set at zero feet, zero inches. And since this is a reflected ceiling plan, you're not seeing the diffuser because it's out of your view range current.
I want to move this up to my anticipated level, my elevation, I'm going to go ahead and change this to nine feet. And I can kind of see I can start to see my diffuser. Also, you may also have these buttons checked.
And this just shows how the air is being drawn or pushed out. I'm just going to go ahead and uncheck those, we don't need those on freight. So there we go.
Now, again, we're putting this into a hard lit ceiling. So I want to make sure that you know, I'm in a decent spot, but we can always refine it later using dimension. So what I'm going to go ahead and do is I'm going to put one about here.
I'm gonna put three in this space, or two in that in this bathroom, and then one of the janitor closet out there and we'll make it we'll make it nice. And then let's say I want to go maybe kind of over the door. We want to go in front of the door here.
So again, we're adding our diffusers for our exhaust. Looking at this here. We do have the toilet partitions.
So I'm going to kind of be mindful of those where I place it there. And then pick there. Perfect.
So let's go ahead. I'm gonna hit escape to cancel out of that. We have this a line of exhaust diffusers and you'll notice that this diffuser looks a little bit different.
So our return has just this one line going across and this is built into the family. Our supply diffusers have an x going across them. And then our exhausts have the line going across.
But then there's only this one leg making up what would be the x. Great. We've populated those. I'm gonna go and stop this video here.
And I'll see you in the next one. Transcribed by https://otter.ai
