Create subassemblies for Civil 3D with the user-friendly interface of Subassembly Composer. The Autodesk Subassembly Composer has been. When it comes to corridor modeling, Civil 3D provides a large number of subassembly parts right out of the box. Since these parts are also. One of the most common Sub-Components I get asked about is the Subassembly Composer for Civil 3D and so I am writing this helpful guide.

Use Subassembly Composer – Create a Civil 3D Subassembly – EnvisionCAD

He has worked in construction management and design since and has implemented and trained companies on Civil 3D for the past year. Drag and drop another point component. Those tools are great the way they are, but we can make them even better through customization and by using Autodesk Subassembly Composer.

At this point you have already calculated all the parameters you need, so now it is time to create a point and a link using those parameters. Add a point below this new auxiliary point.

Think about the subassemblies you use when building corridors. Drag and drop an Auxiliary point and place it below the False label.

Save the file and tutoriao Subassembly Composer. At this point the subassembly is ready and it should look like Figure 3. For this link there is no need to modify anything else.

Atan Slope ; this will give you the slope in radians. This makes the way Subassembly Composer works seem a little weird, so when you design a subassembly it is always a good idea to start by drafting an outline by hand. Add an output clvil. Name this parameter TopWidth with no spaces. This point will be used as the origin and as a reference for positioning the next point.


To understand what Subassembly Composer does, we need to review how subassemblies work, what their components are, and what they do; tugorial, we need to understand codes, points, links, and shapes.

You can solve this in Civil 3D if you create a closed polyline, turn it into a subassembly, then assign codes, links, and shape and it probably would be fine. In AutoCAD we have been doing this for years by subassembpy workspaces containing specific combinations of tools, user profiles with usbassembly configurations for system variables, and templates with pre-existing objects and styles.

AutoCAD has some verticals with specialized tools to design and draft elements pertaining to different industries. Figure 5 civip the schematics of what we want to do and how it will look.

When we customize a program we enhance our productivity because we adapt it to our specific needs. Subassembly Composer is a program where you can create subassemblies from scratch and then use them in Civil 3D just like you would with any other subassembly. Preview is where you see how the subassembly looks as you are putting things together.

Properties is where you set the properties for each of compozer elements you bring in from the toolbox; properties include geometry, calculations, and overall behavior. Set its properties the same way you did for the previous point.

In this article we will see how to use the Subassembly Composer; we will look at its components and create two subassemblies to see how it aubassembly. Packet Settings is where you create and set up the subassembly parameters, targets, and so on. In the Import Subassemblies dialog, browse to where you saved your subassembly and open it. We want to be able to use positive and negative grade values because depending on that, you will draw something different.

For Delta X type BottomWidth—in this case it is going to go to the right from P2 so the value would be positive. For this subassembly we will use output parameters that can be viewed as variables used for calculations. Add a point below the auxiliary point you just created and set its properties as shown tutroial Figure 7.

PI; this will convert the Atan into degrees.

Subassembly Composer has five sections: Drag and drop an Auxiliary point and place it below the True label. Click Create Parameter to create a new parameter. compose

This is the name that this subassembly will use in Civil 3D. Toolbox is where you find all the elements that make up the subassembly such as civl geometry, operators that determine geometry, tools to organize these elements, etc. All of this will make more sense once we start working with Subassembly Composer in the following exercises.
