标准螺纹绘制方法
标准螺纹绘制方法
1、用准备做螺纹的通孔为圆做出一条螺旋线，最好离实体目标高出（一个螺距的距离）少许，以便螺纹做得自然；
2、利用螺旋线和其一端点生成一基准面；
3、正视于此基准面并做草图；
4、做一等边三角形为螺纹的扫描截面。顶角点到螺旋线端点的距离：外螺纹为0.76x螺距；内螺纹为0.65x螺距。
三角形底边到螺旋线端点距离：外螺纹为：0.1x螺距；内螺纹为:0.2x螺距。三角形顶角点、螺旋线端点、
三角边底边中点必须在同一直线上!（做到同一直线上不是很容易，需做一水平辅助线，
利用辅助线端点与螺旋线‘贯穿’，再以此线中点为三角形顶角点做三角形，再用尺寸限制它。）
5、利用三角形草图和螺旋线做扫描切除，即可得所需的标准螺纹。
这是一颗 M5 螺距为0.8mm的螺丝！

可以有實際的示範步驟嗎？謝謝！

这样说，可能没几个人能理解！
上传些动画或图片什么的，
别人看起来就很直观了？
是吗？

这里是一个简单的绘制零件，随手画的，没有按照标准尺寸。SW2005。希望能说明问题。:)

It was very helpfull and I've created attached file according to your instruction, since I can't able to locate Swept Cut feature, just use the Swept Boss/Base, that is why it looks wierd. I'll be greatly appriciated if you could help me to take a look and give some advice.
