Creating the Base SurfaceTo create the hair dryer cover, you first need to create the base surface of the model. Thebase surface will be created by lofting the semicircular sections along the guide curves.These sections will be created on different planes. Therefore, you first need to create threeplanes at an offset distance from the Rightplane .

1. Start SolidWorks part document using the New SolidWorksDocumentdialog box.

2. Create three planes at an offset distance from the Rightplane, as shown in Figure 19-134.For the offset distance of planes, refer to Figure 19-133.

3. Create the sections and guide curves to create a lofted surface, as shown in Figure 19-134.For dimensions, refer to Figure 19-133.

4. Invoke the Lofted Surface tool and create the lofted surface, as shown in Figure 19-135.

Creating the Base Surface for the HandleNext, you need to create the base surface for the handle. The base surface for the handlewill be created by lofting two open sections. The first section for the lofted surface willbe created on a plane at an offset distance from the Frontplane and the second sectionwill be created on the Frontplane. Therefore, you first need to create a plane at an offsetdistance from the Frontplane.

1. Create a plane at an offset distance of 100 mm from the Frontplane.

2. Invoke the sketching environment using the newly created plane as the sketching plane.

3. Create an open sketch, as shown in Figure 19-138, and exit the sketching environment.

4. Now, invoke the sketching environment by using the Front plane as the sketchingplane.

5. Next, create an open sketch, as shown in Figure 19-139, and exit the sketchingenvironment.

6. Using the Lofted Surface tool, create the lofted surface, as shown in Figure 19-140.

Trimming the Unwanted Lofted Surface of the Handle

If you rotate the model after creating the lofted surface for the handle, you will observethat a portion of the lofted surface needs to be trimmed. The method of trimming theunwanted portion of the lofted surface is discussed next.

1. Invoke the Trim Surface PropertyManager and then select the Mutual radio button fromthe Trim Type rollout.

2. Select the trimming surfaces and the pieces to keep, as shown in Figure 19-141. Next,choose the OKbutton from the Trim Surface PropertyManager. Figure 19-142 showsthe resultant trimmed surface.

Creating a Planar SurfaceNext, you need to create a planar surface to close the front face of the handle.

1. Select the plane created at an offset distance from theFrontplane and invoke the sketchingenvironment.

2. Create a closed sketch to create the planar surface and then exit from the sketchingenvironment.

3. Choose the Planar Surface button from the Surfaces CommandManager; the PlanarSurface PropertyManager is displayed. Next, select the close sketch from the drawingarea; the name of the selected sketch is displayed in the Bounding Entities selection areaof the Planar Surface PropertyManager and the preview of the planar surface is displayedin the drawing area. Next, choose the OKbutton from the PropertyManager.

The model after creating the planar surface is shown in Figure 19-143.

Creating Grips on the HandleNext, you need to create grips on the handle to hold the hair dryer. The grip will becreated by extruding the elliptical surface and then trimming the unwanted portion ofthe surfaces.

1. Invoke the sketching environment using the Top plane as the sketching plane.

2. Create a sketch for extruding the surface, as shown in Figure 19-144.

3. Invoke the Surface-Extrude PropertyManagerand extrude the sketch up to the depthof 25 mm. The extruded surface is displayed, as shown in Figure 19-145.

Next, you need to trim portions of the extruded surface and the handle to achieve thedesired shape of grips.

4. Invoke the Trim Surface PropertyManager and then select the Mutual radio button fromthe Trim Type rollout.

5. Select the trimming surfaces and the pieces to be kept, as shown in Figure 19-146.

6. Next, choose the OKbutton from the Trim Surface PropertyManager; the surfacetrimmed. Figure 19-147 shows the resultant trimmed surface.

Creating a Dip on the Upper Surface of the Base SurfaceNext, you need to create a dip on the base surface. To do so, you need to use vario

tools for offsetting the planes, creating lofted surface, trimming, and for creating plansurface.

1. Create a plane at an offset distance of 35 mm from the Top plane.

2. Invoke the sketching environment using the newly created plane as the sketching plan

3. Create the sketch, as shown in Figure 19-148, and then exit the sketching environmen

4. Next, choose Curves > Project Curve from the Surfaces CommandManager and projectthe newly created sketch on the base surface. The model after projecting the sketch isdisplayed, as shown in Figure 19-149.

5. Create a plane at an offset distance of 6 mm from the newly created plane in the downwarddirection.

6. Now, invoke the sketching environment using the newly created plane as the sketching planeand create a sketch, as shown in Figure 19-150. Next, exit the sketching environment.

7. Invoke the Lofted Surface tool and create a lofted surface using the sketch and the pro-jected curve created earlier.

8. The lofted surface, after hiding the base surface, is displayed, as shown in Figure 19-151.To hide surface bodies, expand the Surface Bodies folder in the FeatureManager designtree. Next, select the surface and right-click to invoke a shortcut menu. Choose Hide fromthe shortcut menu; the selected surface is hidden.
