Join Josh Modglin for an in-depth discussion in this video Assemblies, subassemblies, links, points, and shapes, part of AutoCAD Civil 3D Essential Training.
- [Narrator] Previously we mentioned that to create a corridor you need not only the linear path for that corridor whether it's alignment and profile or a feature line, but you also need the typical section to be applied to that path to create the 3-D model. That typical section is referred to as a simple 3-D assembly. Now, an assembly is nothing more than a collection of sub assemblies. Sub assemblies come shipped with auto desk, auto cats simple 3-D.
Over a hundred and fifty different types of sub assemblies. Sub assemblies such as the one you see currently could be lanes or curbs and gutters, sidewalks, daylight functionality and so forth. Now, the sub assemblies are made of three different types of objects or elements, a link, a point and a shape. Now, think about a sub assembly that we're looking at now is a cross sectional view of a curb and gutter.
You create this cross sectional view by having points at important or critical locations, such as the edge of travelway where it's connecting to the lane at the location of the flow line along the face of the curb at the top face of curb, the top back curb and so forth. These are points that make up the sub assembly. Now, between the points and the cross sectional direction you have lines that connect these points.
They're referred to as links for the sub assembly. When the links create a closed space you have the ability to have a shape. So, a sub assembly is made up of these three different components. Now, the interesting thing is these different components or elements that make up a sub assembly are all coded. We're going to use the analogy of social media and we're going to consider the codes apply to each one of these sub components or elements as hashtags and because of that you have the ability to provide or give more codes than just one to each sub component.
So, the point located right at the face flow line that could be coded as face of curb. But, you could also have this one coded in two different ways. You could have it coded at the edge of travelway. You could also have it coded gutter line or beginning of gutter. Now, think about the links. In this case this is the gutter, but it also is the top of your surface. And so, you can have a lot of different codes.
We're going to see how each one of these codes for points, shapes and links within the sub assemblies really drive the creation of the 3-D model and use those codes also not just to create the 3-D model, but to analyze and even create a surface from those codes. We can also stylize information based upon those codes. So, let's review. The typical section you apply to create a corridor model is called an assembly.
An assembly is nothing more than a collection of sub assemblies. Sub assemblies come provided to you from auto desk with your software simple 3-D. Sub assemblies are lanes, curb and gutter and so forth. Sub assemblies are made of points, links and shapes. Points, links and shapes within the sub assembly have codes. Those codes are what we use to stylize, create surfaces and analyze the information within the corridor.
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.
