Assembly Overview

Assemblies An assembly defines the attachment point of a roadway cross-section to the horizontal and vertical alignments (midpoint of the vertical line). Subassemblies attach to the right- or left-hand side at the attachment point to create a road section. An assembly is the centerline of the roadway section. All of the attached subassemblies define the roadway section.

An assembly can be placed anywhere in a drawing. It is usually near a profile, but its location in the drawing is not very important. When building an assembly, you build from the middle out to the right- or left-hand edges.

Assembly styles affect only the color, layers, and symbols of the assembly.

Subassemblies A subassembly represents a portion of a roadway cross-section. For example, subassemblies are pavements, sidewalks, curbs, etc. Each contains points, links, and a shape.

Each point (vertex) of a subassembly has a name.

A point is a potential location for offset and elevation annotation. A point is also a connection point for an adjacent subassembly. For examples, some points are edge-of-travelways, back-of-curbs, gutters, etc. Styles define the properties for the points and their labels.

Subassembly points create feature-lines.

Feature lines are data for surfaces and grading solutions.

A Civil 3D Assembly anchors the subassembly attachments.

A link is a line connecting subassembly points.

A link is data for a slope or grade label. It also represents data for a surface. For example links are pavement, sidewalks, datums, etc. Styles define the properties of a link and its labels.

A shape is an entire subassembly.

A shape is also data for material takeoffs. For example, shapes are curbs, sidewalks, barriers, shoulders, etc. Styles define the properties of a shape.

Each subassembly attaches to the assembly connection point or to a

point on an adjacent subassembly (usually a red circle).

Each subassembly should have a unique name.

Civil 3D Help contains extensive documentation for each subassembly.

The Prospector tab lists each subassembly, but not its attached assembly. The Properties of an assembly lists its subassemblies and their parameters. The Prospector tab separates subassemblies by assigning them individual numbers, (for example, BasicLane - (1), BasicLane - (2), etc.). However, it is best to give each subassembly a more meaningful name, (for example, Right Basic Lane, Left Basic Lane, etc.).

Adding Subassemblies

Civil 3D includes several subassemblies addressing most roadway design needs. All are available using a Tool Palette. The Tool Palette contains seven subassembly categories: Roadway, Basic, Structures, Daylight, Generic, Parking Tools, and Channel and Ditches.

To toggle on or off the palettes window, click the Tool Palettes button, or press <Ctrl + 3>.

Subassembly Parameters Each subassembly has parameters affecting its shape, grades or slopes, and which control the side of the assembly that it is on. The more complex a subassembly, the more parameters it has.

When adding a subassembly, a Properties palette opens, listing all of the subassembly’s parameters.

In the Properties palette, in the Design tab, the Advanced section lists the subassembly’s parameters.

Change subassembly parameters using the Properties dialog box.

When working with the Tool Palettes and Properties palette, you could find it helpful to turn off the Allow Docking option, to prevent them from docking on the sides of the screen. Right-click on the palette title bar to set this option.

Creating a Corridor

A corridor is a model of a roadway design. The corridor model represents a combination of alignment, profile vertical design, and assembly.

The Corridors menu commands: CREATE SIMPLE CORRIDOR or CREATE CORRIDOR process the road design components into a corridor. Each displays the Create Corridor dialog box and can set the same parameters. The difference is that CREATE CORRIDOR is for more complex roadway designs that require offset, width, etc., before creating a corridor.

For small and uncomplicated subdivisions and roads, CREATE SIMPLE CORRIDOR is used.

For complicated designs with several centerlines and controlling baselines, CREATE CORRIDOR is used.

After you enter the information in the Create Simple Corridor dialog box, you identify the names of the horizontal and vertical alignments and assembly. Each item is identified by selecting it in the drawing or by pressing the right mouse button to display a shortcut menu from which you can select the item.

The Logical Name Mapping dialog box for SIMPLE CORRIDORS prompts you for the daylight surface. This step is needed, because the assembly daylights (matches to) to the composite surface.

Corridor Properties

The Corridor Properties dialog box has seven tabs: Information, Parameters, Codes (point, link, and shape), Feature Lines, Surfaces, Boundaries, and Slope Patterns.

Parameters The Parameters tab displays the target DTM, beginning and ending region stations, frequency of sections, and name of the assembly. A corridor can have more than one region and each region can have a different assembly.

Codes The Codes tab lists all of the codes available in the corridor based on the subassemblies in the assembly. These codes are available for section labels and quantity take-off.


Copyrighted

Feature Lines Feature lines are named strings that pass through the codes of the corridor. From any feature line listed in the Feature Line tab, you can export a polyline or feature line.

Surfaces Each assembly link can be data for a surface. The two most common corridor surfaces are top and datum. The top surface shows the final design and the datum surface represents the amount of cut or fill needed to construct the road foundation. The datum surface is a part of the earthwork volume calculations.

A roadway surface cannot have vertical faces.

Boundaries Typically, when building a surface for a corridor, the outermost boundary is used to control surface triangulation. For example, for an assembly with a daylighting subassembly, the best boundary is DayLight. Another type of boundary is used to define rendering material boundaries.

Slope Patterns Slope patterns indicate if a slope is a cut or fill.

Corridor Review and Edit

The VIEW/EDIT CORRIDOR SECTION command reviews and edits sections. Each section represents the assembly and daylight solution along the corridor’s path.

The View/Edit Corridor Section Editor enables you to review and edit each parameter of a subassembly. Any change can apply to the current station or a range of stations.

The arrow icon at the right-hand side of the toolbar hides or displays the parameter list.

Tool Tips

All Civil 3D objects display a cursor tool tip. A corridor displays several entries in a tool tip, for example, the station and offset of all alignments in the drawing, feature lines under the current cursor location, all surface elevations, and other tool tip reports.

Sample Line Groups

Sample line groups are objects that sample corridor elements for cross-sections. The surface(s), profiles, and assembly of a corridor are the basis for sections documenting it.

Adding new data to an existing sample line group is a complex process. If you have existing sample lines and are now creating a piping network, it is best to recreate the sample lines to add in the pipe network data. Otherwise, you should create the pipe network before creating the sample line group.

The Create Sample Line Group dialog box identifies all of the elements in a corridor’s path. The Section sampling defaults area indicates the type of object, where it comes from, whether or not to sample, what style to use for the sections, what layers, and the update mode for the section.

Section styles for a surface assign layer names and properties.

Multi-Purpose styles for an assembly assign its layer and label properties.

Double-clicking on the layer name displays a Layer Definition dialog box.

After adjusting the values for the Create Sample Line dialog box and clicking Ok, the Sample Line toolbar appears.

The Sample Line toolbar is the control center for defining sample lines. The default method is By stations, which means selecting a station location graphically from the screen.

The Pick points on screen method enables you to select points in the drawing defining the path of the section. This type of section can have multiple vertices. The Select existing polylines method uses existing drawing polylines to define a section. The polyline does not have to be perpendicular to the centerline and can have multiple segments. The By station range method prompts for a range of stations, sampling width, geometry points, and other critical sample locations.

The From corridor stations method uses the stations of the corridor as the stations of the sample line. This method also displays the Create Sample Line dialog box to define the station range and swath widths for the sections.

After creating the sample line group, the Prospector tab lists the individual sample lines under the sample line group’s name. Each entry in the list includes all sampled elements for a section.

Section Views

A section view contains sampled surface sections, corridor assemblies, and any pipes or structures. Similar to profiles, sections use a section view to annotate their elevations and centerline offsets. Styles affect the ‘look’ of a section view.

The section view annotates the assembly’s offsets, elevations, and grades. The All Codes style assigned to the Assembly in the sample line group makes all of the points and links available for labeling. The Section labels styles do not interact with the assembly, only with the corridor surfaces.

Section views can be moved and retain the correct information.

The Create Section View dialog box creates a view for a selected section, determines which styles to use, reports the section statistics, and assigns annotation. If you want to annotate only the corridor assembly, all of the other sections should have the No Label style. The label settings in the All Codes style annotate the assembly.

When using the CREATE MULTIPLE VIEW command, there are three methods of creating section views: individually, organized in pages, or stacked in columns and rows.

Create Section View The CREATE SECTION VIEW command creates a single view for selected sample lines.

Create Multiple Views The CREATE MULTIPLE VIEWS command draws sections in a column and row structure. It organizes sections by (All) or as pages (Page). You can define page styles that define sheet sizes and plottable areas (sheet size minus margins and border).

The Group Plot Style option sets the method of creating multiple section views (All or Page).

You can change the view, label, and band set styles for the sections.

Section View Styles A Section view style defines the vertical and horizontal grid and its annotation. The horizontal lines represent the elevations and the vertical lines represent the centerline offset.

Section View Band Styles A band style defines the offset and elevation annotation at the bottom of a section view. The style affects the annotation’s format and which information appears in the band.

Section and Label Styles A section style assigns a layer and other layer properties to a surface section. The section label styles annotate grade breaks, slopes, and offsets.

Multi-Purpose Styles In Multi-Purpose styles, the All Codes code style assigns object and label styles for a corridor assembly. This is the most important style for section labeling.

The All Codes style defines object styles for points, links, or shapes and sets which labels appear in a section view. In the example below, only the daylight link will show a grade label.

All link styles annotate a grade or slope.

All point styles annotate an offset and elevation.

Page Styles A page style defines the plottable area of a sheet size. This is what remains after removing the non-printing margins and border from the sheet size. The style also defines a sheet grid. The Plot Group styles use the grid to space sections on a sheet.

Section1 and Section2 The existing and proposed elevation labels of a section come from the assignment of Section1 and Section2. Section1 is the existing and Section2 the proposed elevation.

Quantity Takeoffs

There are two types of quantity takeoffs for a road design: earthworks and material. Earthworks represents the amount of cut (existing material above the vertical design), or fill (the vertical design above the existing material). Material volumes are the amount of materials needed to build the road. Materials include: asphalt pavement, concrete curbing, subbase materials, and other materials.

Earthworks Earthwork volumes represent an amount of displaced surface materials. The displacement represents the excavation of high or filling in of low points in the existing ground surface, relative to the vertical road design.

The goal of most road designs is creating a balance between the amount of excavated material (called cut) and the amount of material filling in existing low spots to create the roadbed (called fill). On any site, not all of the excavated material (cut) will be reusable. For example, the spoil materials could be from a bog, a type of material that does not compact well, or could be rock debris. The reuse of cut material can be a percentage of the overall cut value and affects the overall earthwork calculation.

The calculation of earthworks is between the Existing Ground and the Datum of an assembly. The datum represents the roadbed on which lie the subbase gravel, asphalt, and concrete materials. Earthwork volumes affect which revisions occur to a roadway design. For example, excessive cut material (material needing excavation) could lead to raising the vertical design or, if possible, moving the horizontal alignment to create less cut.

Material Takeoff The assembly’s subassemblies represent materials available for quantity takeoffs. These quantities come from the subassembly shapes, (for example, curb, pave, shoulder, sidewalk, etc.).

Quantity Takeoff Criteria The Quantity Takeoff Criteria defines the surfaces and materials for takeoff volumes. Take-off criteria identify two surfaces for earthwork calculations and a list of shapes for material volumes. The criteria styles do not identify names of the surfaces or materials; just that there are two surfaces, (one below and one above) or structures ((shapes) pave1, curbs, or subbase) that are materials. When creating volume calculation data, you associate a name with the criteria entry.

Define Materials After defining the volume criteria, you create data from the criteria settings. The DEFINE MATERIALS command sets the alignment and a Sample Line Group to use for data extraction.

When the Edit Material List dialog box appears, you associate surfaces and/or structures (subassembly shapes) to the appropriate entries. Click Ok to exit and Civil 3D calculates the needed report data.

Practice: Quantity Takeoff Task 1: Create an Earthworks Report 1. Continue working in the drawing from the previous practice.

2. From the Sections menu, select Define Materials.

3. In the Select a Sample Line Group, change the alignment name to HWLongfellow – (1), set the sample line group to SL Collection-1, and click Ok to exit.

4. In the Edit Material List dialog box, make sure the Quantity Takeoff Criteria is set to Cut and Fill.

5. Click in the object name cell for EG (<click here to set all>), and select the composite surface from the pull-down menu.

6. Click in the object name cell for Datum (<click here to set all>) and select the HWLongfellow – (1) Datum surface from the pull-down menu.

7. Click Ok to create the volume report data.

8. From the Sections menu, select Generate Volume Report.

9. In the Report Quantities dialog box, set the Alignment to HWLongfellow – (1), the Sample Line Collection and Material list should change to the correct values, click on the Select a style sheet icon to the right-hand side of the current style sheet, select earthworks.xsl from the list, and click Ok to return the Report Quantities dialog box.

10. Click Ok to calculate the earthworks report for the roadway.
