+ * @Finish 目前已实现
+ * 1. 圆弧板垂直切普通板
+ * 2. 普通板穿透切圆弧板
+ * @TODO 当前问题记录
+ * 1. 普通板切圆弧板，凹槽的长度与厚度如何确定？(目前写死厚度切穿， 长度切断)
+ * 2. 圆弧板切普通版, 若二者不垂直，存在夹角，怎么办？(目前不考虑)
+ * 3. 圆弧板切圆弧板，如何处理？(目前不考虑)
+ * 4. 平行情况，如何处理？(目前不考虑)
+ * @Log 2024/06/20
+ * 处理问题1：采用CSG的包围盒与路径求交方式，来确定凹槽的长度
+ * @Log 2024/06/21
+ * 发现问题并处理: 若圆弧板为异形板，垂直切普通板，生成的凹槽还是整段路径
+ * 发现问题并处理: 由于精度问题，导致切割后在切割，依旧有交集，故这里加了体积过滤
+ * @Log 2024/06/25
+ * 优化: 优化体积过滤，改用CSG真实的体积计算
+ * 重构: 重构了代码结构，修复了普通板切圆弧板的bug(采用点集投影，而非之前的包围盒)
+ * @Log 2024/06/26
+ * 处理问题2：采用对CSG上下面进行投影，然后转为面域做并集，从而生成凹槽
+ * @Log 2024/06/27
+ * 优化问题2：面域的布尔运算很慢，容易造成肉眼可见的卡顿(约1-2秒)，现在改用project
+ * @Log 2024/07/02
+ * 发现问题并处理: project存在精度问题，导致凹槽的长度不准确，故做了修正(若快切断则为切断)
+ * @Log 2024/07/10
+ * 优化: 当普通版斜切圆弧板时，采用逆映射生成凹槽轮廓，而非原有的矩形轮廓
+ * @Log 2024/07/11
+ * 优化: 改用C2R生成凹槽的轮廓线，而非之前的project（因为它不准）
+ * 处理问题3：通过逆映射实现圆弧板切圆弧板
