Join Josh Modglin for an in-depth discussion in this video What is a Civil 3D site and parcel?, part of AutoCAD Civil 3D Essential Training.
- [Instructor] So we begin to work with parcels in Civil 3D, again it's good to just pause and get a better grasp of really what are we talking about when we're talking about parcels. Parcels are really another way to describe a property or a spacial area that's been defined by boundaries. And there's the challenge. A parcel is an open space, so in this case, we really have two parcels. The parcel is not the segments. The Earth is split into all these different parcels, all the parcels are shared.
So this parcel here is neighbored by a parcel on this side, this side, this side, this side, all four sides of course and all of the segments that make up that parcel are shared with another parcel. So it's not the segments that make up the parcel. The segments simply create an enclosed space. The enclosed space is the parcel. So really a parcel can never be visually shown, unless you hatch it or something like that, which really goes back to how Civil 3D thinks about creating a parcel.
Creating a parcel in Civil 3D really goes back to a concept we might be used to with AutoCAD. When you hatching, you can pick internal point. It will create a parcel automatically for us when it finds an enclosed space. Enclosed space of what objects? All the objects that are found in the same site. So if we go to Toolspace in a drawing, you'll notice there are sites as part of our prospector here.
Sites really don't apply to a project as much as a refer to a container of objects that interact with one another. So if there are segments, parcel segments or alignments or other objects that are horizontal in nature that are found within the same site and they create an enclosed area, you automatically get a parcel. You can't even control it, beyond of course, putting objects in a different site.
So Civil 3D really handles the parcel creation for you, what you need to provide to Civil 3D are the segments and the site or container for those segments. So let's go to our next couple exercises and see how we provide those segments to Civil 3D to create our parcels.
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.
