SP3D HVAC Practice Lab: Routing a Duct




Routing a Duct System:Route a duct run from the nozzle SP-1 on the equipment AHU-01 in Unit U06 of yourworkspace. After routing the duct, insert a division to split the duct run into two sections andplace a transition on the smaller division. Extend this duct by routing the duct with bends andbranches. Add more ducts by using offset routing. Lastly, add a reducing elbow, a transitionfeature of turn type, to the duct system. After performing these tasks, the final view of yourmodel should resemble Figure 1.

Figure 1: Output- The Final Duct System

Steps:

1. While performing the basic duct routing, specify the following settings: System: A2 > U06 > HVAC > Supply > Ducts Specification: Spec-1 El: 16 ft

2. Add a division to split the duct run into two sections. The division contains two cells.Specify the following setting:

15


20/32




8. Click the Finish button on the Insert In-line Component ribbon to place the division.

Inserting Transition Feature:

Steps:

1. Click the Insert Transition button on the vertical toolbar.2. Select the smaller section of the division as the starting point.3. When you select the smaller section of the division, the New Duct Run dialog box

appears. Retain the properties on this dialog box that you specified while performingthe steps to perform basic duct routing and click OK.

4. On the Insert Transition ribbon, specify the following settings: Width: 1 ft Length: 1 ft 6.00 in

5. Click the Finish button on the Insert Transition ribbon to place the transition.Routing the Duct with Bends and Branches:

Steps:

1. Select the largest port of the duct run as the starting point.2. Specify the following settings on the Route Duct ribbon:

Angle: 90.00 deg Length: 20 ft

3. Route the duct in the North direction.Now, create a duct with a branch at a distance of -10 ft from the header of this duct. Route thisduct using the offset option on the Route Duct ribbon.

Steps:

1. Click the Reposition Target option on the PinPoint ribbon and set the duct with thebend as the target.

2. Click the Route Duct button on the vertical toolbar. You can view your origin at thenew location.

3. On the PinPoint ribbon, specify value of -10 ft for the north coordinate.4. Highlight the centerline of the duct by pointing the cursor on it and click it.

16


21/32




5. The New Duct Run dialog box appears. Retain the same values as specified for theother ducts and click OK. Change your workspace view to the Looking Plan view androute in the West direction.

6. Route the duct at a distance of 1 ft from the grid line.7. On the Route Duct ribbon, specify Plane as Plan Plane. In the Offset drop-down list,

click Set Offset Reference. The Set Offset Reference dialog box is displayed. Set offsetas 1 ft in the Offset box. Make sure that the offset reference is set as Surface by widthunder the Measured from option and click OK.

8. Move the cursor to the grid line to add it to the SmartSketch list.9. Move away from the grid line. A vertical projection line will generate at 1 ft distance as

specified in the Offset box.

10. Click in the graphic view to finish routing.Performing Offset Routing:

Steps:

1. The starting point for the first duct is the duct with branch that you placed in theprevious procedure. Specify Length as 30 ft on the Route Duct ribbon and route in theNorth direction.

2. Route the second duct by selecting the end feature of the transition as the startingpoint. Specify Angle as 90.00 degon the Route Duct ribbon.

3. Specify the following settings on the Route Duct ribbon: Plane: Plan Plane Angle: 0.00 deg

4. Retain the settings in the Set Offset Reference dialog box as specified for the duct witha branch that you routed in the procedure to route the duct with bends and branches.Identify the grid line to route the duct at a distance of 1 ft from it.

5. Select the grid line you identified to add it to the SmartSketch list. Then, move awayfrom the grid line. The vertical projection line will generate at a distance of 1 ft asspecified in the Offset drop-down list in the Set Offset Reference dialog box. Click toplace the duct part.

6. Continue routing from the last duct in the North direction by specifying the followingsettings on the Route Duct ribbon:

Angle: 90.00 deg Length: 30 ft

7. Now, route another duct with a Length of 40 ft from a different point.

17


22/32




8. Place the transition on the end feature of the duct. To place the transition, specify thefollowing settings on the Insert Transition ribbon:

Width: 1 ft Depth: 1 ft Length: 1 ft 6 in Align: Align Bottom Right

9. Use the offset routing to place a duct from the end feature of this transition. Identifythe grid line to route the duct at a distance of 1 ft from it. Again, retain the settings inthe Set Offset Reference dialog box as specified for the last duct you routed using theOffset option. Also, change your Plane to Plan Plane to view the projection linegenerated by the offset constraint.

10. Continue routing this duct in the West direction by 1 ft offset from the grid line. Theonly change you make at this point is to set the offset reference as centerline of theduct. Select the Centerline option under the Measured from option in the Set OffsetReference dialog box.

11. Now, place a duct with a branch from the transition by relocating the target to the startpoint of the transition. Place this branch at 15 ft distance from the start point of thetransition by specifying the value for northcoordinate as -15 ft.

12. The steps to place this branch are same as the ones you followed to place a duct with abranch in the procedure to route the duct with bends and branches except that hereyou need to define the offset using the Set Offset Reference option in the Offset drop-down list. Specifications to create this branch are listed as below:

Width: 1 ft 6 in Depth: 1 ft 6 in Measured from: Centerline Offset: 2 ft

Placing Reducing Elbows:

Steps:

1. Select the end feature of the duct as the starting point.2. Specify the following settings on the Insert Transition ribbon:

Type: Turn Width: 1 ft Depth: 1 ft Throat Radius: 1 ft Angle: 90.00 deg

SP3D HVAC Practice Lab: Modifying HVAC DuctRuns

Modifying the Properties of Duct Runs:

Before modifying the properties of a duct run, ensure that you define the workspace to showUnit U06, switch to the HVAC environment, and select HVAC_CS as the coordinate system.Activate PinPoint and change the Locate Filter to show Duct Runs.

Modify the duct run property by adding a 0.98 in thick polyurethane insulation.

The view of the duct run after adding insulation looks as shown in Figure 1.

Figure 1: Output- Insulated Duct Run

Steps:

1. Click Format on the menu and select the View option.2. In the Format View dialog box, select the Insulation option under the Selected

Aspects category to enable the insulation aspect.
