This article provides detailed instructions on running mains while working with the CAD Teacher VDCI course content for the BIM 321 course, Introduction to Revit MEP. The tutorial includes steps on cleaning up projects, running pipes, drawing slopes, using fittings, and incorporating vents, among other key tasks.
Key Insights
- The tutorial guides on how to run mains by choosing the right diameter for the pipe, drawing the pipe correctly, and ensuring the slope is set at an eighth of an inch for any pipe that's 4 inches and larger.
- It includes details on how to load a different pipe fitting, specifically, the use of tee reducing sanitary which allows for a smaller connection and is more effective for adding more fittings later on.
- The article also emphasizes the importance of incorporating vents in the project, which help in air venting to facilitate the system function, and how to correctly run these up through the roof.
Welcome back to the CAD Teacher VDCI video course content for the BIM 321 course, Introduction to Revit MEP. In the previous video, we went ahead and started cleaning these things up so that we can start putting in our waste piping. What I want to go ahead and do now is I want to start running my mains.
I'm going to run my mains and then we're going to go back and tap all these in. So I need to go ahead and run up to the second floor. So I'm going to go ahead and select this here, my section, and let's go ahead and reduce the size of it a little bit if it's a little large, perfect.
I'm going to go ahead now and rotate that section so I'm looking at this pipe. So I'm going to go RO for rotate, just click anywhere, drag, and I'm going to turn it 90 degrees. There we are.
And I'm going to go ahead so I can see the entire pipe, just expand it out. And now I want to go ahead, I'm going to declick off of that. If you have any open windows, just go ahead and hit close hidden windows up here and I'm going to go ahead and double click to get into this section here.
And then I'm going to go ahead also and go WT for window tile. I tend to like to work with these reversed with the plan on the left and the section on the right. Either way is fine, it's just a personal preference of mine.

Now what I want to go ahead and do is I want to start actually running, I'm going to run this system up and then run it over so that I can catch everything I need to. So I'm going to go ahead, I'm going to go PI for pipe. I'm on that waste piping, let's go ahead and change the diameter to 4 inches.
I'm going to come over here to my section and I'm going to go ahead and pick on this here. I drag up and if you look up here, because I'm connecting it to a 6 inch pipe, it automatically changes the diameter 6 inches. So let's go ahead and change that back to 4. And there we are.
I'm going to go ahead, take it up to here, pick here and then I'm going to start dragging this way. Now we haven't drawn a slope pipe in section before, but our slope tool tip or our slope should still be slope up at an eighth of an inch. Typically any pipe that's 4 inches and larger is typically sloped at an eighth of an inch.
Any pipe that tends to be 3 inches or smaller is at a quarter inch slope. So a quarter inch over 12. If I'm drawing in section, if you notice if I go horizontally, the farther I go, do you notice how that pipe is starting to slope up? So I'm just going to go ahead and draw horizontally and bring it to about right here.
And there we are. I'm going to go ahead and hit escape. And there we are.
I hit ENTER and that doesn't end the chain, it switched my windows around. So I'm just going to go ahead and go as such. And there we are.
We can see our fittings are already in here, everything else is good to go. Now one thing about fittings that we do need to talk about, I'm actually going to go ahead and tap this over just a little bit. This is a standard tee and then it has a couple to reduce.
But there are specific tees that we could use that actually allow us to have a smaller connection here. But I'm going to go ahead and select this pipe fitting here. Now if I pull down on my type selector, you can see that I really don't have that many.
So what I actually want to go ahead and do is let's go ahead and load a different pipe fitting. So I'm going to go ahead and hit escape. I'm going to go ahead, let's go to my pipe fitting here.
And I want to go ahead, let's go load family. I'm going to go down to my pipe. I'm going to go to fittings, PVC, and remember and then schedule 40 and then socket type.
And these are the generic ones. But one that we want to go ahead and bring in is going to be this DWV in this folder here. And we've got to go ahead and find, and I want to find the tee reducing, not the double.
I just want to go ahead and find tee reducing sanitary. And I'm going to go ahead and hit open and bring that in. I'm not going to place it.
I could go ahead and place it if I needed to. But I'm just going to go ahead and hit escape. And to get out of that command, and I'm going to go ahead and select this here.
Pull this down. And as you can see, I now have this tee reducing sanitary loaded into my project. So please go ahead, once you select that there, please select this tee reducing sanitary.
It's going to change it. And as you can see, we have a much smaller connection here which will allow us for more fittings later on. Again, we want to be true to what they're going to be doing in the field.
We have this all set up. Here, good to go. I'm going to go ahead and bring this down just a little bit.
And there we are. The other thing we need to account for is a vent going all the way through the roof. So I'm going to go ahead and actually select this guy.
I'm going to do my plus sign here to make that a tee. I'm going to go ahead and select here, and I'm going to draw a pipe. There we are.
I'm also going to go ahead and change this to say a two-inch vent. So just a two-inch pipe. There we go.
And I'm just going to go ahead and take it up through the roof because, again, we would have that vent there to vent out all you need the air venting to help out with that system. I'm going to go ahead and do the same thing that I did down here. I'm going to go ahead and select this, grab this guy, tee reducing sanitary, and as you can see, it makes it a lot cleaner connection there.
We've gone ahead. We've run our mains. We have our vent piping going up through the roof, which is great.
What I'm going to go ahead and do is let's go ahead and pause this video here. In the next video, we're going to start on the first floor and start getting all of our systems tied into this guy here. See you then.
