Join Josh Modglin for an in-depth discussion in this video Sites, alignments, and alignment types, part of AutoCAD Civil 3D Essential Training.
- [Instructor] Before we get into creating alignments, we are going to take a brief look and see information about the alignment types as well as alignments and their association with sites. So let's go ahead and from the home ribbon create design panel. We're going to choose alignment and alignment creation tools. So let's look a little bit at the dialogue box here with regards to alignments. Alignments, you can have a few different types of alignments within Civil 3D.
You have the offset alignment and we'll talk about that later. Current return alignments which will automatically be created with corridor nor intersections. Rail alignments that deal with with your camp design values and then miscellaneous alignments such as wall or the center line of a pipe network or something similar. Really a lot of times we focus so much on making sure we select the correct type. Whereas, if there is a need to change the type.
Civil 3D will automatically handle that for us. Look at all the other types unless your doing rail design selecting the type really doesn't matter. Even if your drawing manually a wall alignment. Does it matter if within the alignment properties you have the ability to add super elevation design? And so I usually direct and encourage everyone to not really pay attention to the type unless you're doing a rail design. Don't worry about the type of alignment.
Let the software choose for us if it needs to be something different from the center line type. Additionally, notice that an alignment really belongs within a site. However, unlike partial segments an alignment can exist outside of a site. Now if you place them in a site and they interact then with a parcel segments. Parcel segments and alignments are all horizontal geometry involved or contained within your site or container.
So just as we were reminded within parcels in the sites if an alignment and a parcel segment together or even an alignment with another alignment create an enclosed area, you immediately create a parcel. So if you don't want to accidentally create a parcel with the alignments that you're creating or if you don't understand or think there is a need, it's best just to leave an alignment outside of a site. We call these site less alignments.
However, they have the ability to interact with parcel segments and create parcels. So there is a lot of power here with alignments but understanding these key factors will help us speed along as we create and edit our alignments.
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.
