文章分析了表面粗糙度标注的特点和要求，根据标注频度，划分为基本型和加注型两类。对常用的基本型采用标注文本循环利用、“共线”、“贴面”的自动导航及违禁的自行识别等措施，实现其高效、简便和正确的标注。对有特殊要求及复杂的标注，采用追加标注的方法，从而保证了标注软件具有宽广的适用性。 The article analyzes the characteristics and requirements of surface roughness annotation, according to the frequency of annotation, divided into two types: basic type and filling type. The commonly used basic type annotation text recycling, “collinear”, “veneer” automatic navigation and banned self-identification and other measures to achieve its efficient, simple and accurate labeling. On the special requirements and complex labeling, the use of additional labeling methods, thus ensuring the labeling software has broad applicability.
