GD&T基础简介 GD&T的背景 •GD&T是GlobalDimensioningandTolerancing的缩写，即“全球尺寸和公差”。•标准中包含有尺寸标注方法（属我国技术制图标准）和几何公差 （属我国形状和位置公差标准）两大部分。•尺寸标注仅是一种表达方式，PATAC使用了GM北美的图纸规范，将 有专题的具体介绍。•目前，GM标准和我国...
Symbol: Between - to indicate that a profile tolerance applies to several contiguous features, letters may designate where the profile tolerance begins and ends. These letters are referenced using the between symbol (since 1994) or the word between on drawings made to earlier versions of the ...

There are numerous GD&T characteristics, and some of the most commonly used symbols that represent them are shown in the symbol “cheat sheet” below. These characteristics and their symbols fall into four main categories (or characteristics of features): form, orientation, location, and runout...
I want to get lazy and not dimension everything. Can I square symbol this, with CF attached? I don't see a problem with it. ASME lacks in giving examples of square like features where this could be applied. Also, the entire star shape is tapered by 0,5° between planes. How to ...
