Show OriginalSurfaces. Define the support for the three fill boundaries, as shown in Figure 1— Figure 1—44 5. Complete the fill surface. Create another fill surface using the five boundaries shown in Figure 1— Ensure that the adjacent surfaces are selected as support references. Define Tangent as the continuity type.
Figure 1—46 7. Task 6 - Create a single surface feature. Design Since your goal is to create solid geometry from a surface model, all Considerations surfaces extrude and fill need to behave as a single element for a thick surface feature creation to be successful.
To help keep the geometry organized, you will insert a new geometrical set to hold the Join feature that will be created in this task. Design The new geometrical set is positioned directly beneath the previously Considerations activated geometrical set. Click Join. Select any of the surfaces of the model. All nine surfaces should be listed in the Join dialog box, as shown in Figure 1— Listing order might be different in your model. Figure 1—49 6. The join is added to the JoinedSurfaces body as shown in Figure 1— Hide all geometrical sets except for JoinedSurfaces as shown in Figure 1— Figure 1—51 Task 7 - Create solid geometry.
Activate the Part Design workbench. Define the PartBody to be the work object. Use Thick Surface to create a 2mm thick solid from Join. The completed model displays as shown in Figure 1— Figure 1—53 5. Save the file and close the window. Figure 1—54 Goal After you complete this exercise, you will be able to: 9 Use Slab surface modeling techniques 9 Perform surface operations 9 Create surface fillets 9 Project curves 9 Organize wireframe and surface data Task 1 - Open a part file.
Ensure that the model units are set to [mm]. Extrude is located in 1. Create an extruded surface using the following specifications: the Surface toolbar. Rename the completed extrude as [Wheel Extrude].

Create a projected curve using the following specifications: in the Wireframe toolbar. Rename the completed project as [Projected Door Curve]. Projected Door Curve Figure 1—64 6. Repeat Step 4 using Front Project Sketch. Rename the projected curve as [Projected Front Curve]. Projected Front Curve Figure 1—65 7.
Figure 1—66 If a color does not display 9. Using the graphic properties, color the surfaces gray. Save the model. Using the Edge Fillet tool place fillets on the edges of the wheel well as shown in Figure 1— Right-click on Geometrical Set. B-3 Exercise B2 Managing Links C-1 C. You learn new techniques to help create and manage your part designs.
These techniques help to ensure that a part design remains flexible and leads to the creation of robust models. By doing so, you can maximize the flexibility of the design. Considering what if scenarios that might be introduced into the part helps you to create a robust model that requires minimal effort when incorporating modifications.
Consider the following questions when starting a new model: Default Why use default reference planes? Every part contains three default reference planes, as shown in Figure 1—1. They form a foundation for Reference your model and cannot be deleted. Reference planes make an Planes excellent selection as parents for subsequent features, thereby reducing the number of unwanted parent-child relationships. Figure 1—1 Base Feature What is the best choice for the Base feature?
The Base feature of the part is the first geometry feature added to the part e. Select a form that captures the fundamental shape of the model. Active Body Which body should be set to the active body in the model?
As new features are created, they are added to the active body. These bodies can be used to perform boolean operations, group features, and separate model geometry. Features added to one body might not be accessible to other bodies within the same model. The active body is set by right-clicking it in the specification tree and selecting Define in Work Object. Sketch Support What is the best sketch support plane?
It is important to carefully consider this reference, because it establishes parent-child relationships. Do not randomly select a sketch support simply because you think you must. This might create an unwanted parent-child relationship. Whenever possible, use a default reference plane to minimize the number of unwanted parent-child relationships. The selection of this reference also affects the default view of the model.
As you dimension and constrain your sketch, you select references that References determine how the sketch reacts to modification. References can be removed and added as needed in each sketch.
Select references that incorporate your design intent. Positioned The use of a positioned sketch is highly recommended. It enables you to locate the origin of the sketch so that it updates correctly. When the model is modified, it can reposition itself unexpectedly because its origin is not constrained. For example, if the vertical axis of the sketch is constrained to a specific line or edge, the relationship is maintained throughout the design changes. Dimensions Which dimensions are required to drive the design?
