Deepen your understanding of creating pipe networks, starting with deleting unnecessary polylines and creating a combination surface. Learn the importance of targeting the correct surface and the process of pasting surfaces in a precise order.
Key Insights
- The creation of a pipe network begins with deleting unnecessary polylines and making modifications to the drawing.
- When creating a pipe network, it is crucial to target a specific surface. A combination surface can be created to include both proposed work and existing surface, ensuring that the pipe network structures target the correct surface.
- The process of pasting surfaces follows a particular order. The most recent surface that is pasted in will have control over the previous surfaces pasted in, thus it is important to paste first the base surface followed by the rest of the design surfaces.

All right, welcome back. Now that we've talked about pipe network catalogs and parts lists, we're ready to start creating an actual pipe network. But before we do that, we need to do a little bit of housekeeping first.
I've noticed that we still have these polylines in here for these parcels and the grading pads that we created, and they've been bothering me, so I want to go ahead and delete these out. We're going to go ahead and select all of these polylines, and then after we've selected them all, we're going to go ahead and delete them out. Now that we've deleted those out, we do have to make one modification to our drawing to be ready to create pipe networks.
When you create a pipe network, the pipe network is going to target a specific surface. When we create these pipe networks, I don't know if we're always going to be in one surface or another, so I want to create a combination surface that has our proposed work and our existing surface so that these pipe network structures will target the correct surface and have the rim elevations on the surface of either the created design or the existing terrain. So I'm going to go ahead and expand out my Surfaces tab inside of Toolspace inside of the Prospector.
I'm going to go ahead and create a new surface by right-clicking and selecting Create Surface. I'm going to call this surface Finished Construction so that we are targeting a finished construction surface of everything that we have inside of this site. I'm going to go ahead and leave it as Design Topo, and I'm going to go ahead and click OK.
So from here, I'm going to go ahead and go to my Finished Construction surface. I'm going to expand it out. I'm going to expand out Definitions, and I am going to go to Edits.

I'm going to right-click on Edits, and I'm going to select Paste Surface. So from here, when we paste surfaces in, we need to be cognizant of the order that we paste them in. When you paste surfaces in, the most recent surface that you paste in is going to have control over the previous surfaces you pasted in.
And so when we're creating this combination surface that we want to look like our final construction surface, what we're going to be doing first is we're going to paste in our base surface, which is going to be our existing terrain, which is our CIV203 surface. So I'm going to go ahead and select CIV203. I'm going to click OK.
So you can see that we now have a Design Topo showing up as our existing terrain. I'm now going to go ahead and select Edit, right-click. I'm going to choose Paste Surface.
I'm going to go add my Dev Combo because my Dev Combo has all of my roads plus all of my grading pads plus my desilting basin all included inside of that surface. So I'm going to go ahead and click OK. And so what we should see here now is that the rest of the design surfaces have been added into our existing terrain profiles or our existing terrain surface.
So I'm going to go ahead and select this surface. I'm going to go ahead and do an Object Viewer just to see what it looks like and make sure that it's correct. And then we'll go ahead and save off this drawing.
So as I rotate out, what we can see here is that we do in fact have a surface that has our desilting basin. It has our pads. It has our roadway and has all the other pads here.
So I'm good with the surface. I'm going to go ahead and close this off. I'm going to go ahead and turn this surface off completely because I don't need to actually view it.
So I'm going to go ahead and minimize my Definitions, minimize my Finished Construction surface dropdown. I'm going to right-click, click on Surface Properties, and then I'm going to go ahead and select No Display, hit Apply, and hit OK. Now I still can see what my existing terrain is with the gray, and I can see my design terrain, which is this blue and magenta.
I'm going to go ahead and save this drawing, and then I'll meet you in the next video where we'll start creating our pipe network.
