本期繪制電風扇的葉片，先選擇右視基準面，然後繪制成下圖的草圖，接着點選曲面，選擇拉伸曲面，将曲面繪制出來。接着在上視基準面上畫一個圓弧對曲面進行裁剪。裁剪完成後繼續草圖繪制，具體繪制情況如下面的草圖所示。然後選擇圓周陣列，畫出剩下的部分，在進行裁剪，最後就能夠得到以下的形狀。
In this issue, we will draw the blades of an electric fan. First, select the right reference plane, and then draw a sketch as shown in the following figure. Then, click on the surface, select the extruded surface, and draw the surface. Next, draw an arc on the upper reference plane to crop the surface. After cutting, continue sketching, as shown in the following sketch. Then select the circular array, draw the remaining part, crop it, and finally obtain the following shape.
然後呢，就可以對其進行放樣，将其連接配接起來，選擇放樣曲面，然後選擇對應的邊線與引導線，起始和結束限制我們這裡都選擇與面相切。再選擇延伸曲面，将剛才放樣的部分進行延伸。然後點選裁剪曲面，将放樣邊進行修剪。選擇縫合曲面，将葉片與中心不部分縫合起來。
Then, you can lay it out, connect it together, select the surface to be laid out, and then select the corresponding edge and guide lines. We choose to start and end with constraints that are tangent to the face here. Select the extension surface again and extend the part that was just laid out. Then click on the trim surface to trim the lofted edges. Choose a stitching surface to stitch the blade together with the center part.
設定一個如下圖的平行于上視基準面的基準面，在其上進行繪制草圖，然後進行曲面拉伸，深度為70mm，拔模參數為57度，選擇封底。選擇裁剪曲面，将其裁剪成如下形狀。點選圓角進行倒圓角處理。然後選擇圓周陣列，将剛才完成的一片扇葉圓周成四片。最後将整個葉片縫合起來，再加厚即可。
Set a reference plane parallel to the top reference plane as shown in the figure below, sketch on it, and then perform surface stretching with a depth of 70mm and a draft parameter of 57 degrees. Select the back cover. Select the crop surface and crop it to the following shape. Click on the rounded corner for fillet processing. Then select the circular array and divide the previously completed fan blade into four circles. Finally, stitch the entire blade together and thicken it.
