<p dir="auto">关系式驱动参数之间的数学关系：</p>
<p dir="auto">齿轮关系式示例：<br />
m = 2 (模数)<br />
z = 20 (齿数)<br />
d = m<em>z (分度圆直径)<br />
da = d+2</em>m (齿顶圆)<br />
df = d-2.5*m (齿根圆)</p>
<h2>族表(Family Table)</h2>
<p dir="auto">族表用于管理相似零件的变体：</p>
<ol>
<li>创建基础模型</li>
<li>添加可变参数</li>
<li>生成族表</li>
<li>添加各实例的参数值</li>
</ol>
<h2>应用场景</h2>
<ul>
<li>标准件库：螺栓/螺母/垫圈</li>
<li>模架系列：不同尺寸模架</li>
<li>零件变体：长中短版本</li>
<li>参数化设计：输入参数驱动全模型</li>
</ul>
