IGES 格式概述</h2>
|
|||
|
|
<p>IGES (Initial Graphics Exchange Specification) 是一种旧式但广泛使用的 CAD 数据交换格式。 采用 80 字符固定宽度记录格式，分为 5 个区域：</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><b>S (Start)</b>: 自由格式注释</li>
|
|||
|
|
<li><b>G (Global)</b>: 参数分隔符、单位、精度等全局设置</li>
|
|||
|
|
<li><b>D (Directory)</b>: 实体目录（类型、线型、颜色等属性）</li>
|
|||
|
|
<li><b>P (Parameter)</b>: 实体参数数据</li>
|
|||
|
|
<li><b>T (Terminate)</b>: 文件结束标记</li>
|
|||
|
|
</ul>
|
|||
|
|
<h2><a class="anchor" id="autotoc_md13"></a>
|
|||
|
|
支持的实体类型</h2>
|
|||
|
|
<p>主要支持几何和拓扑实体：</p><ul>
|
|||
|
|
<li>Type 100: Circular Arc</li>
|
|||
|
|
<li>Type 110: Line</li>
|
|||
|
|
<li>Type 116: Point</li>
|
|||
|
|
<li>Type 126: Rational B-Spline Curve</li>
|
|||
|
|
<li>Type 128: Rational B-Spline Surface</li>
|
|||
|
|
<li>Type 108: Plane</li>
|
|||
|
|
<li>Type 186: Manifold Solid B-Rep Object</li>
|
|||
|
|
<li>Type 502/504/508/510/514: B-Rep 拓扑（顶点/边/环/面/壳） </li>
