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.

Customize it and make it yours!

Packet Settings is where you create and set up the subassembly parameters, targets, and so on. This will be the origin and insertion point. Add a point below this new auxiliary point.

The codes used when creating a subassembly will work with the codes in the Code Set Styles, point codes will create feature lines, and links can be used for surface creation. Properties is where you set the properties for each of the elements you bring in from the toolbox; properties include geometry, calculations, and overall behavior.

To understand what Subassembly Composer does, we need to review how subassemblies work, what their components are, and what they do; specifically, we need to understand codes, points, links, and shapes. By doing this we are composet the grade value into a slope value. This is the name that this subassembly will use in Civil 3D.

Use Subassembly Composer – Create a Civil 3D Subassembly

The direction is input because it is an input parameter, meaning that the user will input the value. In this article we will see how to use the Subassembly Composer; we will look at its components and create two subassemnly to see how it works.

Subassemblies are the building blocks for assemblies in Civil 3D, and we can look at assemblies as cross sections for roads, rivers, embankments, etc. For Delta X type BottomWidth—in this case it tutoriwl going to go to the right from P2 so the value would be positive. Switch to the Insert tab and from the Import panel select Import Subassemblies.


Subassembly parts Figure 1 shows the basic anatomy of a subassembly with codes, points, links, and shape. Set its properties the same way you did for the composre point. Import into Civil 3D Now you can use the slanted curb subassembly like a regular curb subassembly.

For Output Parameter select Atan and for value, type Math. When we customize a program or a graphical user interface it usually is because we want to modify the way things look and behave.

Compower has worked in construction management and design since and has implemented and trained companies on Civil 3D for the past year. Subassembly Composer has five sections: Auxiliary points are used as references for other points and they are not shown in the subassembly. Drag and drop an Auxiliary point and place it below the True label. Now you have two parametric subassemblies made from scratch.

As an AutoCAD user, you are accustomed to drawing lines in a very subasxembly way. Atan Slope ; this will give you the slope in radians. Toolbox is where you find all the elements comloser make up the subassembly such as its geometry, operators that determine geometry, tools to organize these elements, etc.

For this point there is no need to modify anything else. We want to be able to use positive and negative grade values because depending on that, you will draw something different. In AutoCAD we have been doing this for years by using workspaces containing specific combinations of tools, user profiles with specific configurations for system variables, and templates with pre-existing objects and styles.

Add another point element, which will be the top right corner of the subassembly. Flowchart is where you lay out the workflow: Home Articles Customizing with Subassembly Composer. Set the side to Right. Add a link component to the flowchart; no need for points here because the link will connect to existing points.

Constant Length and Varying Slope Subassembly This subassembly works similar to the LinkWidthAndSlope generic subassembly, but this one keeps the length constant regardless of the slope. These subassemblies are rather simple, but I think you can see the potential of Subassembly Composer. Click Create Parameter to create a new parameter. All of this information can help you to reverse engineer these subassemblies, have a better grasp of how they work, and create parametric subassemblies in Subassembly Composer.

Now that you know how to use Subassembly Composer, go ahead and create your own subassemblies, draw them in your mind, then on paper, and then build the subassembly. Make sure the type is set to double, which is the type of parameter that will let you input values with decimal figures.

At this point the subassembly is ready and it should look like Figure 3. When we customize a program we enhance our productivity because we adapt it to our specific needs. Name this parameter TopWidth with no spaces.

Set a default value for this parameter of covil. Repeat the previous steps for the other parameters and make sure your parameters match what is shown in Figure 2.
