To Create Assemblies

To create an assembly

When you add a set of subassemblies sequentially to a baseline (for example, lane, curb, sideslope, then ditch), they are all added to the same subassembly group. The next time you select the assembly baseline, a new group is created and subsequent subassemblies added belong to the new subassembly group.

1. Click Home tabCreate Design panelAssembly drop-downCreate Assembly Find.
2. In the Create Assembly dialog box, in the Name field, enter a name for the assembly.
   Note: To name the assembly, select its default name and enter a new name, or you can use the Name Template.
3. For Description, enter an optional description of the assembly.
4. For Assembly Type, select the type of corridor in which the assembly will be used.
   • Roadways: This value must match the roadway type that you specify in the Calculate Superelevation wizard on the Calculate Superelevation - Roadway Type Page.
   • Railways: This value must be set to Railway.
5. For Assembly Style and Code Set Style, either accept the default style, select another style, or create a new style.
6. Click to select a layer.
7. Click OK.
8. To insert the assembly into the drawing, click a baseline location in the drawing.

   The assembly name is displayed under the Assemblies collection in the Prospector tree. A vertical line with a circular marker in the middle is inserted into the drawing. This is the assembly baseline location point, where you will attach one or more subassemblies.

9. Select a subassembly from a tool palette, or from a tool catalog through the Content Browser.
   Note: Not all subassemblies in Autodesk Civil 3D are located on a tool palette by default. All subassemblies are stored in the Content Browser, and you can add subassemblies that you use frequently to a tool palette for easy access.
10. To attach the subassembly to the assembly baseline location, select the baseline point or the baseline marker. Typically, the baseline marker displays as a vertical line.

    The subassembly name is displayed in the Subassemblies collection in the Prospector tree. A subassembly group is added to the assembly.

11. To add subassemblies to the subassembly just added, do any of the following:
    • Select a subassembly in a tool palette, or in a tool catalog, and then select an appropriate marker point on the previously added subassembly.
    • When you are prompted to select a marker point, you can choose to either insert a subassembly between two existing subassemblies, replace an existing subassembly, or create a detached subassembly.
    • Select a subassembly that is already attached to an assembly and click Copy To Assembly, Move To Assembly, or Mirror Subassemblies on the Modify Subassembly panel of the Subassembly tab. You can also select multiple subassemblies using these features.
