The following steps are required to complete this tutorial: The base feature of the model is a sweep feature. Create the path of the sweep feature on the XZ plane, refer to Figure 135. Next, define a work plane normal to the path and position it at its start point of the path, refer to Figure 136. Create the profile of the sweep feature on this work plane, refer to Figure 137. Use the Sweep tool to create the sweep feature, refer to Figure 138. Figure 135 Path for the sweep feature in the isometric view Figure 136 Work plane normal to the path

Figure 148a Model of a Nut with threads Figure 148b Dimensions of the Nut

The following steps are required to complete this tutorial: Create the base feature, refer to Figure 149. Figure 149 Base feature of the Nut

Create a hole concentric with the base feature, refer to Figure 150. Figure 150 Model after creating the hole feature

Fillet the top and bottom faces of the cylindrical feature, refer to Figure 151. Figure 151 Model after filleting the top and bottom edges

Tutorial 5 In this tutorial, you will create the solid model of the receiver of a phone shown in Figure 160a. The dimensions of Section 1 and Section 2 of the receiver are shown in Figures 160b and 160c. Section 3 is a mirror image of Section 1, but you need to create it separately as an individual sketch. Figure 160a Solid model of the receiver

Figure 160b Dimensions of Section 1 Figure 160c Dimensions of Section 2

The following steps are required to complete this tutorial: Start a new metric template file and draw the sketch for Section 2 on the XY plane. As sketches can be created in any sequence while creating a loft feature, you do not need to create Section 1 first Draw the sketch for Section 1 on the XZ plane. Exit the sketching environment. Again, define the sketch plane on XZ plane and draw the sketch for Section 3. Exit the sketching environment and invoke the Loft tool. Select three sections to create the loft feature.
