Finishing the Vent System for the Bank of Classrooms: A Detailed Guide

Completing the Vent System for the Remaining Classrooms: Advance Techniques and Color Coding

Discover the step-by-step process of completing a bank of classrooms with their vent system in a building model. Detailed instructions are provided on how to effectively use tools in the Revit software to accomplish this task.

Key Insights

  • The article provides a thorough walk-through on the process of completing a vent system in a bank of classrooms using Revit software. It emphasizes the importance of using the right tools and settings to achieve the desired result, such as using the correct pipe size and adjusting the section view for better visibility of the model.
  • The author also demonstrates how to overcome potential challenges during the modeling process. For instance, if one forgets to change the pipe size during the modeling process, there's no need to delete and redo the entire model. Instead, the software allows for easy modification by simply selecting the affected area and modifying it to the correct size.
  • Besides modeling, the author also touches on the importance of differentiating various systems within a model for easy identification. This is illustrated by assigning different colors and line types to the vent system in the model. This ensures that the model is not only accurate but also visually organized and easy to understand.

In the previous video, we finished one bank of classrooms with their vent system. Now we got to go ahead and finish the other bank.

So I'm going to go ahead and go over to my level two ceiling plan, grab my working section. I'm going to drag it down to this other bank of sinks here. I'm just going to make the section look a little bit better.

And I'm going to close my 3D view here. Make sure you're in this section view so you can see these sinks and everything. And we're going to just continue with the same path we've been going.

So I'm going to go here to pipe. I'm going to make sure it's on a vent, two inch. There we go.

Get the connector, drag up. We got to place this first and go up to that level one. There we go.

And then continue working down. We got to put in on the second floor first. And then once we've done it on the second floor, we can tie in our first floor.

Go up, go up. And then here I'm ready to go. So again, I'm going to click here, but again, I got to change this back to a two inch, 45 out, come up, get above that other sink, tie back in.

Same thing. So PI for pipe, start about there, come over 45 degrees. Oh, change my two, change the two inch first.

Remember to do that. Come up. And there we go.

Let's try it. Let's check a couple of the settings real quick. So let's try PI.

Let's see what happens if we turn off automatic connect. Does that want, that still changes it to a three inch and it doesn't give us our fitting. We do definitely do not want to do that.

Back to automatically connect. There just isn't anything here to say. I don't want you to match the size of it.

So this is just how we're going to have to go about it. Two inch, go up. There are no pipe settings that would allow me to do that, unfortunately.

So there's that. Come here, two inch. There we go.

There we are. Pipe, two inch, come up. There we are.

And we finished that side. Let's go ahead, go over to our plan view, switch, flip our section and move it over. Now I'm going to go PI.

We're going to again, start at the connector here, go into that level line. There we go. And just keep panning around and keep working.

Go through, come up, go through. I think that's the last one. I'm going to extend out this section just a little bit just to see.

Yeah, we're good. Got everything there. Now it's time to do the 45 portions.

So PI, again, make sure you change it to the right size. Two inch, go over. There we go.

Let's see. Maybe I forget to change it. Let's just, let's just say, hypothetically, I forget to change it.

We kind of have this situation going on. How, you know, I don't want to have to undo and redo that. Well, if I tab select, I could just grab that and change it to a two inch.

And there we go. So again, if I did forget, I could go ahead, pick out. I forgot.

I'm just going to say that I forgot to change it, even though I know I need to there to there. But what you could do is on that vertical, I tab select pick, it goes to the fittings there and I can change it to a two inch. So there are some easy, fast, easy ways that if you, if you forget a little step, you don't always have to just delete it and go back.

I'd highly recommend for everything that is in Revit. I would definitely check out the different options that you have when it comes to tab selections and know exactly what those are. So two inch, it's just a very, very nice tool to have in the repertoire.

And there we go. We're just going to have these ones going through the roof. We're not going to combine them or anything like that.

And there we go. If I go ahead, let's take a look at our 3D view. We're looking pretty good.

Now, the last thing I want to do is make sure that this vent system, and this can be set up anytime we could set this up at the beginning, but I want to make sure that this vent system is colored differently. We want to go ahead and assign a color to that and possibly a line type to it. So what I'm going to go ahead and do is I'm going to expand out my family's location.

I'm going to scroll down and find piping systems. If I go to piping systems, we have that vent pipe here. That is part of the predefined system.

Remember we created natural gas. We can always create whatever we need to, but I'm going to go here to vent right, click type properties. So I'm going to look at the graphic overrides.

If I go to the graphic overrides here, we could assign a pattern if we wanted to and a color. So let's pick a color. We already have blue and red for that.

We have the green, the light green for our actual sanitary. We have the cyan for our gas. So let's see here.

What do we want to go with? Maybe we'll go with a, we could stay on the same color scheme and go with a dark green. Let's kind of see how that looks. Maybe apply.

I think I might want a little bit more contrast just so I can see specifically what is vent. We're going to go with maybe a magenta apply. Yeah, there we go.

I like the, I like the, the contrast. So I know exactly. We could also assign a specific line pattern to it.

If we wanted, let's say that we wanted our vent lines to be like this dash dot, right? So this dash dot, okay. Apply. So depending upon the scale, it's going to give us a different thing.

If I go to say like a 16th of an inch scale, it's not giving me that line type because the runs are too short. If I go to say a half inch scale, you can see how those pipes really start to represent. If I look over at say here, you can see on my ceiling plan, that pipe type is there.

Let's go ahead. I'm going to go back into my type properties at it. I think we're just need to be a little, we can go dash dot three 16th of an inch, and you can see a little bit more again, you can play with this and kind of find something you like.

Your office may have a specific standard that they like to use. I'm hesitant to just use dashes. The reason being is that typically dashes are used to represent underground or other lines, but I wanted to show this.

We'll go dash dot one eighth. I think that will look pretty good. There we go.

So that is our vent piping system there. So that it will look different from our, and that represents in both the course view, but let's say I change, or let's say I have it on the fine view. I received both.

If I change it to the course view, it gives me that look, which I think is actually really where it stands out that we're able to see what those vent lines look like and really be able to discern what is happening. If I was to change this and as we start to get into the documentation, if I was to change this to just a fine view or a course view, you can see how that, let me change the scale here a little bit, see how that starts to read a lot easier, especially if you're talking about wanting to do some sort of isometric 3D view. It really starts to highlight how that looks different there.

Great. I think we're pretty good. I think we've pretty much completed the system.

We're going to do one more video, kind of just taking a peek. We'll look over the system, make sure that everything is good and connected. I think we might have a couple of little spots where we may need to clean some things up.

We'll go through and kind of talk about some strategies on how to clean those up and then we'll get into the documentation. See them.
