Transcript of Civil3D 2009 Skill Builder Conditional Sub Assembly

Adding Cut and Fill Conditions to a Corridor AssemblyThis Skill Builder demonstrates how to use the ConditionalCutOrFill subassembly to build a corridor assembly that applies different subassemblies depending on the cut or fill condition at a given station. The conditional subassembly enables you to reduce the number of corridor regions and assemblies that you have to maintain. This Skill Builder covers the following topics:

Importing a subassembly Examining corridor sections Adding conditional subassemblies to a corridor assembly Applying a meaningful naming convention to subassemblies Adding multiple levels of conditions to a corridor assembly

The ConditionalCutOrFill subassembly, as well as a variety of other specialized corridor subassemblies, is available exclusively in the Autodesk Subscription Center. The Autodesk Subscription Center is a password-protected online application where Autodesk Subscription members access program benefits, downloads, and exclusive community content. For more information about the Autodesk Subscription program, visit www.autodesk.com/subscription. The ConditionalCutOrFill subassembly controls the application of subassemblies that are attached to it. In the following example, three conditions are defined. The subassemblies that are applied after the shoulder depends on which of the three conditions is met at the current station: If the condition at the station is...A: Cut

then...add a ditch with specified daylighting parameters. daylight to the target surface at a specified slope. add a guardrail, extend the shoulder, and then daylight to the target surface at a specified slope.

B: Fill < 3 meters

C: Fill > 3 meters

You can define multiple levels of conditions for an assembly. The previous example can be expanded to specify which subassemblies to apply depending on the resulting daylight from a previous condition: If the condition at the station is...A1: Cut

then...apply specified benching parameters to the target surface. add a berm, and then daylight to the target surface at a specified slope.

Conditional Subassembly Best PracticesThis section outlines best practices for using the ConditionalCutOrFill subassembly. These best practices are demonstrated in this Skill Builder.

Use a descriptive naming conventionEach subassembly should have a specific, meaningful name to make it easy to identify when you are assigning targets. Meaningful names also help you identify subassemblies in the Subassemblies collection in Prospector. Use a single daylight link for each conditionIf you attach a ConditionalCutOrFill subassembly to a standard daylight subassembly, you should omit the daylight link in the host subassembly. If the

daylight link is included in the host subassembly, then daylight links will be created for both the host subassembly and the attached subassembly.

Installing the Skill Builder FilesFor best results, save the files that are included with this Skill Builder the My Documents\Autodesk\Skill Builders\Conditional Subassembly folder, creating the Conditional Subassembly folder, and the Skill Builders folder if it does not exist. Other Skill Builders for AutoCAD Civil 3D should also go into the Skill Builders folder.

Importing the Conditional SubassemblyIn this exercise, you will download the ConditionalCutOrFill subassembly from the Autodesk Subscription Center website, and then import the subassembly into a new tool palette. 1 From the Autodesk Subscription Center website, download the Imperial ConditionalCutOrFill.pkt file to the My Documents\Autodesk\Skill Builders\Conditional Subassembly folder. The PKT file contains all the files necessary for the subassembly to work on your computer. 2 In the AutoCAD Civil 3D window, click File menu Open. Navigate to the My Documents\Autodesk\Skill Builders\Conditional Subassembly folder. Open Civil3D_2009_SkillBuilder_Conditional_Subassembly.dwg. This drawing contains an existing ground surface, an alignment, profiles of the existing ground and proposed finished ground, a corridor, and a corridor assembly. In later exercises, you will modify the corridor assembly and then examine the results on the corridor. 3 If the Tool Palettes are not visible, on the command line, enter ToolPalettes. 4 In the Civil 3D - Imperial tool palette group, right-click a tool palette tab. Click New Palette. 5 Change the New Palette text to Conditional. 6 Click Corridors menu Utilities Import Subassemblies. 7 In the Import Subassemblies dialog box, for Source File, click .

8 In the Select File dialog box, navigate to the My Documents\Autodesk\Skill Builders\Conditional Subassembly folder. Select the Imperial ConditionalCutOrFill.pkt file. Click Open. 9 In the Import Subassemblies dialog box, select the Catalog Library/My Imported Tools check box. Click OK. The ConditionalCutOrFill subassembly is imported to both the Conditional tool palette and the My Imported Tools tool catalog in Content Browser. 10 Close the Content Browser window.

Examining the Existing Corridor in SectionIn this exercise, you will examine how the daylight subassemblies are applied to the corridor model in section. You will notice stations at which the current daylighting parameters are inappropriate for the site conditions. 1 Click Corridors menu View/Edit Corridor Section. In the lower viewport, click the corridor. 2 In the View/Edit Corridor Section Tools toolbar, use the Through Road assembly is applied to at the corridor stations. buttons to examine how the

The assembly creates a ditch on either side of the road. At the beginning and end of the corridor, the cut and fill is relatively consistent on both sides.

You will address two conditions in this Skill Builder:

First, the fill condition from stations 0+00 through 1+00 produces a relatively deep fill on the left side. While the corridor assembly is constructed appropriately for other regions of the corridor, you will modify the design to use a different approach in this region.

Second, notice that from stations 5+00 through 8+00, a much greater amount of material must be cut from the left side of the corridor. While the Through Road assembly is appropriate for the majority of the corridor, it is not ideal for these stations.

In the following exercise, you will insert the ConditionalCutOrFill subassembly into the Through Road assembly, and then specify different parameters to be applied in different fill conditions. You will address the cut conditions in a later exercise. 3 In the View/Edit Corridor Section Tools toolbar, click to return to station 0+00.

Adding Conditional Subassemblies to the Corridor AssemblyIn this exercise, you will add conditional subassemblies to the corridor assembly. You will specify separate subassemblies to apply at varying cut and fill conditions. 1 In the Civil 3D - Imperial tool palette, on the Conditional tab, click ConditionalCutOrFill. 2 In the Properties palette, set the following parameters:

Side: Left Layout Width: 20.0000

4

Layout Grade: 4.000:1 Type: Fill Minimum Distance: 0.0000 Maximum Distance: 5.0000

NOTE The Layout Width and Layout Grade parameters only affect the appearance of the subassembly in layout view. These parameters enable you to position the conditional subassembly and subassemblies that are attached to it, but do not affect the corridor model. 3 In the drawing window, in the top viewport, click the left guardrail to add the ConditionalCutOrFill subassembly.

4 Add a second ConditionalCutOrFill subassembly to the left guardrail using the following parameters:

Side: Left Layout Width: 20.0000 Layout Grade: 1.000:1 Type: Fill Minimum Distance: 5.0001 Maximum Distance: 9999.0000

5 Add a third ConditionalCutOrFill subassembly to the left guardrail using the following parameters:

Side: Left Layout Width: 20.0000 Layout Grade: 1.000:1 Type: Cut Minimum Distance: 0.0000 Maximum Distance: 9999.0000

6 Using the Imperial - Daylight tool palette, add a DaylightBench subassembly to the Fill 5.00 : 9999.00 conditional subassembly using the following parameters:

Side: Left Cut Slope: 4.000:1 Max Cut Height: 5.0000 Fill Slope: 4.000:1 Max Fill Height: 5.0000 Bench Width: 6.0000 Bench Slope: -10.000%

7 Press Esc to exit subassembly placement mode. 8 Select the original left ditch subassembly. Right-click. Click Move To. Click the FIll 0.00 : 5.00 conditional subassembly. 9 Select the ditch subassembly that you just moved. Right-click. Click Copy To. Click the Cut 0.00 : 9999.00 conditional subassembly. When you are finished, the assembly should look like this:

Adjusting Subassembly Properties and Assigning Meaningful NamesIn this exercise, you will adjust the properties of two of the subassemblies, and then assign descriptive names to each of the subassemblies in the Through Road assembly. Each subassembly should have a specific, meaningful name to make it easy to identify when you are assigning targets. Meaningful names also help you identify subassemblies in the Subassemblies collection in Prospector. 1 In the drawing window, in the top viewport, select the red assembly marker. Right-click. Click Assembly Properties. 2 In the Assembly Properties dialog box, click the Construction tab. Notice that the subassemblies that you added to the left side of the assembly display the default names followed by the side to which they were added. When you build a complex assembly, you should assign meaningful names to the subassemblies so that you can easily identify them when setting corridor targets. This is also a good practice when a drawing contains multiple as
