本期绘制电风扇的叶片，先选择右视基准面，然后绘制成下图的草图，接着点击曲面，选择拉伸曲面，将曲面绘制出来。接着在上视基准面上画一个圆弧对曲面进行裁剪。裁剪完成后继续草图绘制，具体绘制情况如下面的草图所示。然后选择圆周阵列，画出剩下的部分，在进行裁剪，最后就能够得到以下的形状。
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.
然后呢，就可以对其进行放样，将其连接起来，选择放样曲面，然后选择对应的边线与引导线，起始和结束约束我们这里都选择与面相切。再选择延伸曲面，将刚才放样的部分进行延伸。然后点击裁剪曲面，将放样边进行修剪。选择缝合曲面，将叶片与中心不部分缝合起来。
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.
设置一个如下图的平行于上视基准面的基准面，在其上进行绘制草图，然后进行曲面拉伸，深度为70mm，拔模参数为57度，选择封底。选择裁剪曲面，将其裁剪成如下形状。点击圆角进行倒圆角处理。然后选择圆周阵列，将刚才完成的一片扇叶圆周成四片。最后将整个叶片缝合起来，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.
