Join Eric Chappell for an in-depth discussion in this video Understanding the parts list, part of AutoCAD Civil 3D: Pressure Pipe Design.
- [Narrator] Parts lists are ways of storing collections of the pipes, fittings, and appurtenances that you are going to use to build your pressure networks. Let's start learning about parts lists by taking a tour of one that's already built. The quickest way to get to your parts list in your drawing is to select a pressure pipe in the model, and then expand parts list, and then edit pressure parts list. Once I'm here, I can select which parts list I want to modify, and in this case I'm going to select water existing.
I'll select that and click OK, and we get our first look inside a pressure network parts list. First we have the information tab where we can provide a name and a description for the parts list. The way you usually organize or create your parts list is based first on the type of system. So you may have one for water, one for gas, one for force mains, and there may be others that you have as well, and then there may be more specific purposes within each system type. So within water you may have one for existing and one for proposed, or one for chilled water versus hot water, something along those lines.
So, beneath the system heading there may be additional parts list based on more specific purposes. So in a given drawing, you may have three or four or even more parts list depending on how your templates and your other standards are organized within your company or organization. This particular pressure network parts list is for water that is existing. So we're modeling existing water lines beneath the ground. Now, as you can see there are several tabs here. The first one is pipes, and then we see fittings, and appurtenances.
So as you might guess, we've got a catalog of items for pressure pipes, a catalog for fittings, and a catalog of appurtenances. So within each one we have what's called a part family. So first we see the name of the parts list, then we see the part family, which happens to be ductal iron, and then if I expand that I see the individual parts beneath the part family. So each one of these items is an individual part.
So, because we're dealing with pipes, we see a 10 inch pipe, 12 inch, a 16 inch, and six inch. Now for each part, there's more to it than just grabbing a 3D model of whatever we have out of the catalog, and in this case because we're dealing with pipes, it's not just a 3D model. It's actually the extrusion of a shape. So when we create a pipe in the model, we're extruding a 10 inch diameter, a circle in this case, or a 12 inch, or a 16 inch. But there's more to it than that.
What's the default style that's going to be assigned to each one of those parts? And you can see they each individually have a unique style that can be assigned to them. Now these are all assigned to be the same, but they could actually be different. Same thing with a render material and same thing with a pay item. Each one can have its own pay item assigned. So there's the ability to control and automate the stylization, the appearance, and the quantity tracking of each individual part.
Imagine the time savings and the flexibility that that can lead to. Let's look at fittings now. Same deal, we have the name of the parts list, then we have in this case three part families, a ductal iron cross, ductal iron elbow, and a ductal iron tee, and within each part family we've got individual parts. Notice the icon here that allows me to assign, in this case, a style down through all the parts within that part family.
So, if I were to click this icon, and let's say choose fitting for this, click OK, it would assign that change through all the parts within that family, as opposed to going to an individual item, and changing just that item's style. So these buttons can be very handy because quite often what you assign to one item in the family you want to assign to the others as well, like render material. Now where things probably get a little bit different is with quantity take off, or the pay item, where you might want these to be individual pay item.
So again, we're grabbing a 3D model out of the catalog, but then we're also giving it a style, render material, and pay item. So there are many things being automated here, not just the insertion of a 3D model, and by the way, there are even more ties to this that we can't even see at the moment. For example, a lot of the styles that come out of the box are ones that you can configure yourself, actually utilize this name in the labeling. So, you may want to take this name for example, and instead of calling this very long part name, we might want to simplify this to maybe a 16 by 10 cross, and even capitalize it so when it comes out in the label it appears the way we want it to be labeled.
So you can even automate labeling from within the parts list provided your labels reference these part names, and that can be another layer of automation that you can tie to the parts list. Appurtenances, same thing, we've got the name of the parts list, then the part family, and then within each part family we have individual parts. We can control the default style, render material, and pay item. And then not much going on in the summary tab, some basic information, and some statistics.
It's not really like a style, even though it has the summary tab, we don't have full access to all of the different values underneath. Okay, so now you have an understanding of what makes up a parts list and you're ready to continue with the upcoming videos.
