Introduction

This module contains a self-paced project. The purpose of this project is to provideyou with an opportunity to practice the skills you have learned in the class withoutrelying on step-by-step instructions.

In this project, you create the design framework to build the parts for a car door

inner panel.

Objectives

After completing this module, you will be able to:

Apply the skills you've learned to real-world design projects.

Course Project Designing the Inner Door Panel

Scenario

Orion Motors is designing a new car. The digital model of the exterior surfaces isready. Currently, stiffener body parts and interior trims are being designed. Youare part of the design team, which is designing the inner door panel. The digital

surface model of the exterior surface is available for reference.

You design the inner door panel. The car door assembly is provided for you and

you are to create an inner door panel that fits to the assembly. The assemblycontains a skeleton model with references required for creating the inner doorpanel.

Throughout the next few days, you design the assembly components using a top-down design approach. Use the supplied models to complete sections of the project

laboratories.

Course Project Designing the Inner Door Panel (cont.)

The project laboratories take you through the design of the door inner panel. Youmodel the panel surfaces, the surfaces for the lock detail, the design details for the

trim panel to be housed, and add strengthening details to the part.

Project I Creating the Inner Door Panel Design Framework

You start the first project by copying the references from the skeleton part suppliedto you. You copy the references required for creating the shut line of the door, thedoor lock, the window opening, and the door trim panel zone.

Exercise 1: Creating the Inner Door PanelDesign Framework

Objectives

After successfully completing this exercise, you will know how to:

Copy design references from a skeleton model to a part to be modeled.

Create design references in the model.

Scenario

As a member of the design team working on the door inner panel, you begin bycopying the references from the skeleton part supplied to you. You copy thereferences required for creating the levels in the door.

Task 1. Open the car door assembly.

1. Set the working directory to:

C:\users\student\Surface_WF3\module_04 .

2. Open the CAR_DOOR_RIGHT.ASM.

3. If necessary, click Datum Planes , Datum Axes , Datum Points ,

and Coordinate Systems from the main toolbar to disable their display.

4. Review the structure of the assembly. Notice there is a skeleton and asurface model of the outer door panel.

Car Door Assembly

5. Select the CAR_DOOR_RIGHT_SKEL.PRT from the model tree, right-click and

select Open.

o Click Datum Planes , Datum Axes , Datum Points , andCoordinate Systems from the main toolbar to enable theirdisplay.

o Expand the model tree and notice the various publish geometry

features for the window, door lock, speaker, and door inner panelsupplied in the skeleton part.

6. Click File > CloseWindow to return to the assembly.

7. Select the DOOR_OUTER_RIGHT.PRT from the model tree, right-click and

select Open.

o Examine the model tree and notice that the references for the outer

door surface are available as a publish geometry feature.

Car Outer Right Door Part

8. Click File > CloseWindow to return to the assembly.

Task 2. Create the DOOR_INNER_PANEL_RIGHT.PRT and assemble it.

1. Click Create Component from the feature toolbar.

o In the Component Create dialog box, select Part as the type.

o Type DOOR_INNER_PANEL_RIGHT.PRT as the name.

o Click OK.

2. In the Create Options dialog box, select Copy From Existing for the

creation method.

o Click Browse to copy from a template model.

o Select the START_PART.PRT and click Open in the Choose Templatedialog box.

o Click OK.

o Right-click and select Default Constraint.

o Click Complete Component from the dashboard.

Task 3. Copy the required references from the DOOR_OUTER_RIGHT andCAR_DOOR_RIGHT_SKEL models.

1. Select the DOOR_INNER_PANEL_RIGHT.PRT from the model tree, right-clickand select Activate.

2. Click Insert > Shared Data > Copy Geometry.

o In the model tree, expand DOOR_OUTER_RIGHT and select the

DOOR_SURFACE publish geometry feature.

o Click Complete Feature from the dashboard.

You can use the Copy Geometry and Publish Geometry data sharing features to transfer a

collection of references from one model to another. It is easier to select a publish geometry

feature than selecting individual references when transferring references with a copy geometry

feature. Also if the source model changes, the copy geometry and publish geometry features

update and therefore the geometry referencing them also updates correspondingly.


o In the model tree, expand CAR_DOOR_RIGHT_SKEL and select the

SHUT_LINE_REFERENCE copy geometry feature.



o In the model tree select GLASS_REFERENCE.



o In the model tree, select LOCK_REFERENCES.



o In the model tree, select DOOR_LEVEL_1.



o In the model tree, select EMBOSS_REFERENCES.



o In the model tree, select WINDOW_PROFILE.

Task 4. Review the created geometry.

1. Select the DOOR_INNER_PANEL_RIGHT.PRT from the model tree.

o Right-click and select Open.

o

Notice that many of the required curves, surfaces, axes, and planeshave been easily added to the part as copy geometry features.

Geometry Transferred with Copy Geometry

2. Click File > Close Window to return to the assembly.

Task 5. Continue copying references.

1. Select the DOOR_INNER_PANEL_RIGHT.PRT from the model tree, right-clickand select Activate.


o In the model tree, expand CAR_DOOR_RIGHT_SKEL and select

DOOR_LEVEL_2.



o In the model tree, select DOOR_LEVEL_3.


4. Click Insert > Shared Data > Copy Geometry.o In the model tree, select INNER_TRIM_PROFILE.


5. Select the DOOR_INNER_PANEL_RIGHT.PRT from the model tree.

o Right-click and select Open.


8/14

o Notice that additional curves, surfaces, axes, and planes have been

added by using the copy geometry to reference publish geometryfeatures.

Additional References

Copied from the Skeleton

Task 6. Rename the copy geometry features for easy reference.

1. In the model tree, select Copy Geometry id 23.

o Right-click and select Rename.

o Type DOOR_SURFACE as the new name.

o Repeat the previous step to rename the remaining copy geometry

features, as shown in the following figure.
