The half section is not widely used in detail drawings because of difficulties in dimensioning internal shapes that are shown in part only in the sectioned half（Fig.24.3）. The greatest usefulness of the half section is in assembly drawing, in which it is often necessary to show both internal and external constructions on the same view. Broken-Our Sections. Where a sectional view of only a portion of the object is needed, broken-out sections may be used（Fig.24.4）. An irregular break line is used to show the extent of the section. Offset Sections. In order to include features that are not in a straight line, the cutting plane may be offset, so as to include several planes. Such a section is called an offset section. Figure 24.5 shows a typical use of an offset section. Aligned Sections. To include in a section certain angled features, the cutting plane may be bent to pass through those features. The features cut by the cutting pane are then imagined to be revolved into a plane. Figure 24.6 is an example of aligned section.

水平有限，手工翻译。

由于在剖视图中显示的内部尺寸标注的困难，剖视图并不广泛的应用在零件图中。剖视图最大的用处是在装配图中。它往往在同一视图中显示内部和外部的结构。局部剖视图-只有部分对象的剖视图是需要的。局部剖视图可能被使用（图24.4）。剖面线显示截面的范围。偏移剖面为了包含特征将不使用直线。切割平面可能会偏移，以便包含多个平面。这样的一个剖面被叫做一个偏移剖面。图24.5显示了偏移剖视图的一个典型的应用。旋转剖视 为包含一个特定角度的特征，剖切面可能弯曲来穿过这些特征。这些被剖切平面剖开的特征被想象的旋转到一个平面。图24.6就是旋转视图的一个例子。
