Adding Supply Air to Bathroom in Revit MEP Course: Step-by-Step Guide

Integrating Supply Air Diffusers into the Mechanical System in Revit MEP: A Strategic Approach

Learn about the various steps involved in adding supply air to a bathroom in the Revit MEP course Mechanical offered by VECI. The process involves tying in the supply air where necessary, selecting the right working view, deciding on the placement of diffusers, and copying the setup to the second floor.

Key Insights

  • The course involves working with rigid and flex connections in an exhaust system for a bathroom, and tying it into a fan on the roof.
  • Adding supply air involves placing diffusers, selecting the right air terminal, and understanding the hosting options for successful placement.
  • The placed diffusers are then copied and pasted to the second floor using the copy and paste to the current view option, making the process more efficient.

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 VECI video course content for the Revit MEP course Mechanical. In the previous video, we went ahead and finished up our exhaust system over the bathrooms here. And we talked a little bit about the different systems and how these are kind of the rigid connections versus the flex connections and connected that entire system together and tied it into a fan up here on the roof.

Now we want to go ahead and add a little bit of supply air to this bathroom. So what I'm going to go ahead and end up doing is where we're tying that in off of this guy here. So I first want to go to my level one ceiling mechanical, my working view.

Again, I'm doing my work. I want to be in my working view. What I'm going to end up doing here is we have to remember that we have hard lid ceilings in these locations.

So the exact location of the diffusers can kind of be really wherever we want. But we want to make sure that we know that it's going to be in a hard lid ceiling and not like a acoustic ceiling tile like it is over in the other classrooms. So the first thing I'm going to place are going to be my diffusers.

So I'm going to go to systems. I'm going to go to air terminal. I have my exhaust grill selected as that is the last air terminal that I populated.

So I'm going to pull down, I'm going to type in supply in the search because there's a couple of different supplies here. I'm going to use supply diffuser, rectangular face, round neck hosted. And I'm going to use the 24 × 24 inch face with an eight inch neck hosted.

There we go. Now since this one is hosted, this is going to come up with the hosting options. So like we have previously have place on vertical face, place on face or place on work plan.

We're going to be using the place on face option, which it should be selected by default. If it's not selected, you can just go ahead and click on it. I'm also going to check my other parameters over here.

I know that I don't want to see these arrows automatically. So I'm just going to go ahead and uncheck those right away. Perfect.

And then the system classification is going to be supplier because the connector inside of this family is told to be a supply system. So I'm going to go ahead, populate one about here. I'm going to kind of get them away a little bit from the exhaust registers, but there, and then we'll place like another one here.

Same thing. We'll kind of try to mirror what we have on the opposite side, but it's not wanting to give me a snap. It kind of does.

When I get close down here, you'll notice that it wants to give me that metal line snap. Once I cross this wall though, it really doesn't want to give me that one. We can always use the line tool to get in line later.

They go there. And I'm going to go ahead and then go there. My escape.

Let's go ahead and make sure those are aligned. I'm going to use this as my base. So AL for a line pick here, pick here.

I don't have my multiple alignment checked. So, but I'm not going to worry about checking you for this one. And there we go.

I'm going to take those and now copy them up to the second floor so I can select all those diffusers I just populated. Right? So again, select one, hold control, and then just select the others. I'm going to go ahead.

I'm going to hit copy. I'm going to go into my ceiling two mechanical working. And then I would just go up here to paste and paste the line to current view.

And there we go. If I hit escape, there we are. And I have those.

Perfect. Now what I want to go ahead and do is let's go ahead and take a peek at the duct. I'm going to bring this working section over so that I can kind of see what I'm looking at here.
