那里的尺寸系列包含三种符号。
There the dimensional series are indicated by a combination of three symbols.
技术制图。几何形位公差的符号。比例和尺寸。
Technical drawings. Symbols for geometrical tolerancing. Proportions and dimensions.
并能正确标注尺寸及加工表面符号，公差与配合。
Learning to mark dimensions, manufacturing surface symbols tolerance and fittings correctly.
当具有公差要求的被测要素为线或平面时，将指引线箭头和基准符号指在线或平面上，且必须与尺寸线错开。
If the element being tested with a tolerance requirement is a contour line or surface, point the arrow and datum symbol to the contour line or surface, and keep it away from the dimension line.
当被测要素为轴线、中心线或对称平面时，指引线的箭头和基准符号应与该要素的尺寸线对齐。
If the element being tested with tolerance requirements is an axis, centre line or symmetrical plane, the arrow and datum symbol should be aligned to the dimension line of that element.
零件尺寸的两个极限之差称为公差，这是一个没有符号的绝对量值。
The difference between the two limits of size of a part is called the tolerance, an absolute amount without sign.
本文所述的交互式绘制零件图软件不用编写程序可描绘任意图形，标注尺寸及公差，书写字符及画表面粗糙度符号，并可起到数字化仪的鼠标器作用。
This software can plot freely, draw any figure, mark dimension and tolerance, write symbols and draw surface-roughness symbols. It can also function as a mouse in digitalizer.
