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.

Now you have two parametric subassemblies made from scratch. For Delta Y enter 0. Make sure the type is set to double, which is the type of parameter that will let you input values with decimal figures. In this article we will see ssubassembly to use the Subassembly Composer; we will look at its suhassembly and create two subassemblies to see how it works.

These values are calculated and used for other parameters. Click Create Parameter to create a new parameter. For Output Parameter select Atan and for value, type Math. Slanted curb in Subassembly Composer Tutodial this point the subassembly is ready and it should look like Figure 3.

The display name can have spaces and that is how it is going to display in Civil 3D. 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.

Toolbox is where you find all the elements that make up the subassembly such as its geometry, operators that determine geometry, tools to organize these elements, etc. Name this parameter TopWidth with no spaces.

Ciivl about the subassemblies you use when building corridors. 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. At this point the subassembly is closed, but it is empty. 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.


Subassembly Composer and its Applications Subassemblies are the building blocks for assemblies in Civil 3D, and we can look at assemblies as cross sections compoesr roads, rivers, embankments, etc. Drag and drop another point component.

Add another Output Parameter. I hope these two exercises shed some light on how to use Subassembly Composer.

Preview is where you see how the subassembly looks as you are putting things together. Customize it and make it yours! By doing this we are converting the grade value into a slope value. When we customize a program or a graphical user interface it usually is because we want to modify the way things look and behave. The direction is input because it is an input parameter, meaning divil the user will input the value. Hand-drawn schematics Figure 6: He has worked in construction management and design since and has implemented and trained companies on Civil 3D for ciivil past year.

Set Output Parameter to Slope, which is one of the output parameters that was created in the packet settings. Add another point element, which will be the top right corner of the subassembly.

AutoCAD has some verticals with specialized tools to design and draft elements pertaining to different industries. The icvil 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 Figure 1: The location of suhassembly point will be measured in terms of deltas in the X and Y direction with respect to the origin point.


The process is similar in that you have to create parameters and use those parameters to define targets. From the toolbox under the Geometry category, drag a Point component and drop it into the Flowchart window.

For this point there is no need to modify anything else.

Use Subassembly Composer – Create a Civil 3D Subassembly

As an AutoCAD user, you are accustomed to drawing lines in a very visual way. The steps below outline the process to create a simple slanted subassembly.

In the Import Subassemblies dialog, browse to where you saved your subassembly and open it. 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. Subassembly Composer also requires communicating with the program using its own language, almost like coding; in this case it uses.

Switch to the Sjbassembly tab and from the Import panel select Import Subassemblies. From the toolbox in the Miscellaneous category, drag Set Output Parameter and drop it into the flowchart. Add another Output parameter from the toolbox.

We want to be able to use positive and negative grade values sbuassembly 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. Flowchart is where you lay out the workflow: Add a point below this new auxiliary point.

Subassembly parts Figure 1 shows the basic anatomy of a subassembly with subaxsembly, points, links, and shape. When we customize a program we enhance our productivity because we adapt it to our specific needs.
