面 ‣ 交集(布尔)

使用选中部分对未选中几何元素执行布尔操作。尽管可以使用 布尔修改器 进行非破坏性编辑，但在编辑模式访问布尔操作更加快捷。

布尔运算

• 相交

  与 差值 相反(目标网格内的所有内容都被保留)。

  并集

  目标网面添加到修改的网面。

  差集

  The target mesh is subtracted from the modified mesh (everything outside of the target mesh is kept).

解算器

Algorithm used to calculate the boolean intersections.

• 快速

  Uses a mathematically simple solver which offers the best performance; however, this solver lacks support for overlapping geometry.

  • 合并阈值

    认定靠近的表面为接触的公差。可以通过调高该值，来解决实际的交叉部分未被侦测到，或者由于边线未被侦测为重叠而产生额外几何体的问题。

    Warning

    阈值接近面尺寸时，会导致解算变慢，所以通常保持该阈值为一个较小的值。

  准确

  Uses a mathematically complex solver which offers the best results and has full support for overlapping geometry; however, this solver is much slower than the Fast Solver.

交换

Changes the order of the operations when using Difference to determine which side is kept.

自身

Correctly calculates cases when one or both operands have self-intersections, this involves more calculations making it slower.
