3D Instance: Drawing a computer power supply cover using 3D design software

Thread Content

The example we will cover today involves using the Zhongwang 3D design software to create a computer power supply cover through sheet metal modeling. Let’s begin with our example: 1. Click the [New] button to create a new part file. 2. Right-click in the drawing area and select “Insert Sketch”; the Sketch property manager will appear. Choose the XZ plane and click OK to start sketching, with the sketch being created as shown in 3.1. Click to exit the sketch. Click the \"Sheet Metal Stretch\" button on the Sheet Metal toolbar; the Sheet Metal Stretch property manager will appear. Select the newly drawn \"Sketch 1\" for the \"Outline\", set the starting point to \-75 and the ending point to 75, as shown in Figure 3.2, then click OK to complete the Sheet Metal Stretch command. As shown in Figure 3.3! Figures 3.1, 3.20, 3.21. 3. Click the 【Add Full Flange】 button on the 【Sheet Metal】 toolbar to enter the 【Add Full Flange】 property manager; set the values as shown in Figure 3.4, and after clicking OK, the result will be as shown in Figure 3.5. Then use the \"Sheet Metal Unfold\" button on the 【Sheet Metal】toolbar to bring up the \"Sheet Metal Unfold\" property manager, and set a fixed plane, as shown in Figure 3.6. After clicking OK, it will appear as shown in Figure 3.7. Figures 3.4, 3.5, 3.6, 3.7. 4. Right-click in the drawing area and select “Insert Sketch”; the Sketch property manager will appear. Select the sheet metal top surface and click OK to start sketching, with the sketch being created as shown in Figure 3.8. Click to exit the sketch. Click the \"Sheet Metal Stretch\" button on the Sheet Metal toolbar; the Sheet Metal Stretch property manager will appear. Select the newly drawn \"Sketch 2\" for the \"Outline\", set the starting point to \"0\" and the ending point to \"-1\", as shown in Figure 3.9. Click OK to complete the Sheet Metal Stretch command. As shown in Figure 3.10! After completing the stretching, use the 【Sheet Metal Folding】 button on the 【Sheet Metal】 toolbar; this will bring up the 【Sheet Metal Folding】 property manager. Select the current sheet metal in the ‘Solid’ option, and after confirmation, the result will be as shown in Figure 3.11. Figures 3.8, 3.9, 3.10, 3.11: Note that careful observers will notice three red dotted lines on the left side of the curve in Figure 3.8. Before drawing this curve, I used the \"Curve Reference\" feature in the [Tools] menu; it helps us to more easily identify the boundary points of the curve. Everyone can practice more with the references in these sketches; it will make it easier and faster for you to draw shapes. 5. Right-click in the drawing area and select “Insert Sketch”. The Sketch property manager will appear; after selecting the sheet metal top surface, place the mouse on the ‘Up’ tab within the available options. Right-click in the drawing area and choose the negative Y-axis, then click OK to start sketching. The sketch should be created as shown in 3.12. Click to exit the sketch. Click the \"Sheet Metal Stretch\" button on the Sheet Metal toolbar; the Sheet Metal Stretch property manager will appear. Set the values as shown in Figure 3.13, then click OK to complete the process. Figures 3.12 and 3.13: 6. Click the 【Add Full Flange】 button on the 【Sheet Metal】 toolbar to enter the 【Add Full Flange】 property manager, and then create the schematic diagrams shown in Figure 3.14 (length=10, radius=2.5, other settings at default), Figure 3.15 (length=10, radius=2.5, other settings at default), and Figure 3.16 (length=actual value determined during debugging, radius=2.5, other settings at default). Figures 3.14, 3.15, 3.16: 7. Right-click in the drawing area and select “Insert Sketch”; the Sketch property manager will appear. On the Plane tab, select the outer surface that was last “added with a full flange”. Place the mouse over “Up” in the available options, right-click in the drawing area and select the Z-axis, then click OK to start sketching. The sketch should be created as shown in Figure 3.17. Click to exit the sketch. Figure 3.17 (the diameters of the concentric circles on the right are 10, 20, 30, 40, and 50 respectively). 8. Click the \"Sheet Metal Stretch\" button on the \"Sheet Metal\" toolbar; the \"Sheet Metal Stretch\" property manager will appear. Select the newly drawn \"Sketch 4\" for the \"Profile\" field, and set the start and end points by selecting the boundaries of the two faces, as shown in Figure 3.18. Click to confirm and finish the \"Sheet Metal Stretch\" command. Figures 3.18 and 3.19: 9. Right-click in the drawing area and select “Insert Sketch”; the Sketch property manager will appear. Select the bottom surface of the sheet metal that is to be stretched in Sketch 1 to start sketching, as shown in Figure 3.20. Next, click the \"Create Blinds\" button on the \"Sheet Metal\" toolbar to enter the \"Blinds\" property manager, and set the values as shown in Figure 3.21. After completion, use the \"Mirror\" function in the 【Tools】toolbar, selecting the plane as the mirror surface with the XZ plane, to achieve the result shown in Figure 3.19. Figure 3.20: 35 in the upper left, 45 in the lower right, 65 at the bottom. Figure 3.21: 10. Right-click in the drawing area and select “Insert Sketch”; the Sketch property manager will appear. Select the bottom surface of the sheet metal to be stretched in Sketch 1 to start sketching, as shown in Figure 3.22. Next, click the [Create Embossment] button under the [Sheet Metal] toolbar. Refer to the settings shown in Figure 3.23. Figure 3 is obtained (computer power supply cover). Note: This example focuses on sheet metal design in ZW3D; therefore, when using most of its functions, the approach taken is to utilize the features related to sheet metal along with sketching tools and other relevant functions. There are many ways to create the cover for a computer power supply, and one can use ZW3D’s solid modeling and sheet metal functions to design the desired product. I also look forward to receiving any good suggestions from everyone. Figure 3.22 (length 80*height 30, chamfer of 10); Figure 3.23: Figure three (computer power supply cover)
