Join Josh Modglin for an in-depth discussion in this video Editing a pipe network: Plan, part of AutoCAD Civil 3D Essential Training.
- [Instructor] Once we've taken our first draft at creating our pipe network design, let's see some of the edit functionality with our pipe network. So we're going to open up our 10_03_PipePlanEdit, and see how we can edit our design for our pipe network. The first thing we want to look at is how we can edit the labels. Currently, all of our structures are labeled with the pipe network name and then a number. And what we want to do is, in this case, we are going to label or name our structures from the lowest structure as being number one, and working our way up.
So instead of picking on each structure, which in this case, all the structures are kind of hidden beneath the labels, what we're going to do is go to our Prospector, under Pipe Networks, Networks, Sanitary. You know what those little dots are, they mean there's a collection of objects there. So if I select Structures, it will show all of the different structures. We're going to identify through these labels the different structures. In this case, structure Sanitary5, we're going to rename to SSA-1.
These green marks show me that no rules are broken for my structures at the moment. I go to the next structure, 4, and that's going to be SSA-2, and so on. 3 is SSA-3, try to name it the same thing and it just ignored it. So it doesn't allow for identical names within the same network. SSA-4 and the last one is SSA-5.
So a great way to quickly and easily name the different structures, and we can do the same with pipes. We can go through, and you see the rules are broken on the pipes. And it will even tell you which rule is broken in different ways as well. So let's identify these different pipes. We can do it simply by the names and, again, work our way up. So this one is SSA-2 to SSA-1.
This is SSA-3 to SSA-2, and so on. One other thing, if we go back to Structures, all the descriptions, which we use in the naming in our label styles, all of them are these really long names applied based upon the part family. So we want to change the description of every one of these structures. Now we saw how we can do each one individually.
If we want to change all of them, we simply right-click on the header name, choose Edit, and we're going to change it 48" MANHOLE. Now all of the descriptions have been chagned for every single structure that we have within this pipe network. Some simple housekeeping, we can also do the same with our labels, we can move the labels. What about the design itself? Well, let's go ahead and we'll move SSA-3 label.
And hit Escape, and then I'm just going to pick the structure here. And you notice that the structure has a little leg sticking off. That grip gives us the ability to rotate the location of that structure. In this case, it's a concentric manhole. But if we had a square structure or an inlet, rotation would be critical. Additionally, we can swap the part so that we can go from a 48 inch to a 60 inch manhole, or some other part. And remember when we swap the part, we're doing more than just changing the size or the type, we're applying a different style, different rules, and so forth.
In this case, we're just going to grab by picking the square grip and sliding the structure to the center of the circle next to SSA-3. When we do that, notice the pipes automatically moved. It's because the pipes are connected to the structure. So it's so much easier to move the structure and allow the pipes to follow instead of trying to move the pipes that are connected to the structure. Lastly, we can even add pipes and structures after the fact.
For example, in this case, we have a branch from SSA-3 to SSA-3.1. To do that, pick any portion of the pipe network pipes or structures, and choose Edit Pipe Network from the contextual ribbon. It will open up that same toolbar we were working with, giving us the same parts list. And so we're going to change our structure to 40 inch manhole, and our pipe to 6 inch DIP. Now this gets a little bit more tricky, because we don't want two structures here at SSA-3.
And right now, every single time we pick we add a structure. So we're going to start by just adding a structure, not pipes and structures. And we're just going to add up structure right at the circle there, labeled 3.1. So a new structure's been added. So we have all the structures that we need for our system. So now we're just going to change to Pipes Only. And notice the direction I'm laying out. I'm going from upstream to downstream. And so I'm going to turn off my Object Snap, and literally get close to that structure.
Now I'm not dead on that structure, I can't see the structure. But do you see the little icon to the top right of my crosshairs? It looks like a circle with four lines out of it. It's kind of like an Object Snap, it connects the pipe, if I pick on it, to that structure. And so when I get close to this structure, it does the same thing, it floats and gives me that little glyph. And that tells me that pipe now will connect to that structure automatically and is drawn all the way to the center of the structure.
Now if I move that structure, the pipe would follow. So a lot of different controls that we have, being able to add these different items, we can even have, when we add a pipe, if we float over an existing pipe, it will place and connect those together. Pipes and Structures, it'll drop a new structure in and split a pipe in between. So a lot of controls with being able to edit pipe networks. We looked at making changes to the names, making changes to entire descriptions.
And, of course, we can change that with styles and so forth. Notice we still have one of these here. Let's go ahead and change that, SSA-3.1 and change this one to 48" MANHOLE, and so on. So a little housekeeping. We could do the same within what's called our pipe network vista, and we'll see some more controls of that in our Profile Control. We, of course, edited by adding as well.
This course gets you up and running with AutoCAD Civil 3D. First, instructor Josh Modglin shows how to model a surface, lay out parcels, and design geometry, including the making of horizontal alignments and vertical profiles. Next, Josh demonstrates how to create corridors, cross sections, pipe networks, and pressure networks. Then, he covers working with feature lines and grading objects, and how to share your data. He wraps up by providing an overview of plan production tools.
