Edit the curve shown in Figure 1— Double-click on this curve Figure 1—34 3. The curve is a spline curve with a tangency condition applied to both ends. This is shown in the Tangents Dir column, as shown in Figure 1— Figure 1—35 4. Click to view the tangency references.
Select Extremum. Design For this end of the curve, a plane is used to defined tangency. If a Considerations plane is used as a Tangents Dir reference, the curve is normal to the selected plane at that end.
Figure 1—36 6. Right-click on Plane. Ensure that the two reference planes are visible in the model, as shown in Figure 1— These two reference planes should be visible. Figure 1—38 Task 4 - Create a spline curve with tangency. Show the NewSurfaces geometrical set. Ensure that Curves is the active work object. The specification tree and model display as shown in Figure 1— Define in work object Figure 1—40 4. Click Spline and select the two Extremum points that have been shown.
Select the appropriate reference planes to define tangency for each of the two points, as shown in Figure 1— Figure 1—41 6. Define NewSurfaces to be the work object, as shown in Figure 1— Define in work object Figure 1—42 2.
Click Fill and select the four boundary curves shown in Figure 1— Figure 1—43 3. 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]. Figure 1—56 3.

Wheel Front Split Figure 1—62 9. Split Swept Surface. The cutting element is Wheel Outside Split. Rename the split as [Body Split]. Join displays in the 1. Join Swept Surface. Rename the Join as [Surface Join]. Projection displays 4. 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. The Group dialog box opens as shown in Figure 1— Figure 1—68 2. Select Wheel Extrude in the specification tree and every feature after it, as shown in Figure 1— Click in the Group dialog box. The specification tree displays as shown in Figure 1— Note that only the selected features display in the group.
This tool simplifies the specification tree. Figure 1—70 4. The wireframe and surfaces not in the group can be shown by right-clicking on Group-Geometrical Set. Figure 1—71 5. Right-click on Group-Geometrical Set. The specification tree only displays the features placed in the group. Save the model and close the file.
You use the mask functionality to create two mask states of the model. The third and final mask that you create will be used to return the model to a state that displays all geometry in the part.
Goal After you complete this exercise, you will be able to: 9 Create masks for a part file Task 1 - Open a part file. Figure 1—72 Task 2 - Create a mask. Click Mask in the Tools toolbar, as shown in Figure 1— Each side of the box has a green handle, as shown in Figure 1— Your bounding box could Green handles on each side of the box have a different orientation then the one shown.
