Title must be in size 5 for Chinese, and 3.5 for English, and text are to be written in size3 for Chinese and 2 for English, drawing No. and material are also expected to be insize 5.1.3 图号栏Drawing No.外框大小12×55，用细实线绘制，文字与标题栏中的图号文字一致(即5号字)。

Frame is to be made in the size of 12 X 55, in continuous thin line, text is to be in the same size (5) as the title.1.4 明细栏Specification每增加一行，间隔9mm，字高：中文：3，英文：2.5，宽度≤0.75。

Row space is 9mm, character height:: 3 for Chinese, 2.5 for English, width≤0.75.1.5 字体Font图纸中所采用的字体，除单位名称用楷体_GB2312外，其余用HZ(romans,hzjd)字体。

Except company name may use楷体_GB2312, all font in the drawings are requested to be in HZ(romans, hzjd)1.6 图线Drawing Line1.6.1 图线分为粗细2种，粗线的宽度为0.35mm，细线的宽度为0.13mm。

Drawing line includes two types: thick line, with the width of 0.35mm; and thinline, with the width 0.13mm.1.6.2 同一图样中，同类图线的宽度应基本一致。

虚线、点划线及双点划线的线段长短和间隔应各自大致相等。

Lines for the same drawing shall be in the consistent width, dashed line, dottedline and double dotted line must be in the consistent length and space.1.6.3 绘制圆的对称中心线时，应超出圆外2～5mm；首末两端应是线段而不是短划；圆心应是线段的交点。

在较小的图形上绘制细点划线或双点划线有困难时，可用细实线代替。

Center line shall be 2-5mm outside the circle; the start and the end shall be inshort continuous line instead of short dashed line; circle center must be thejunction of the lines. When dotted thin line or double dotted thin line is toosmall to be drawn, it may be replaced with continuous thin line.1.6.4 建议虚线与虚线（或其它图线）相交时，应线段相交；虚线是实线的延长线时，在连接处要离开。

Suggest the continuous part cross when dashed lines (or other lines) meet;dashed lines shall be apart from the continuous line when become the extension.1.6.5 画局部放大图时，应用细实线圈出被放大部分的部位，并用罗马数字顺序地标记。

在局部放大图的上方中间标注出相应的罗马数字和采用的比例。

When drawing needs to be partially enlarged, the enlarged part shall be markedout with continuous thin line and digital sequence. And the relevant digitalsequence and the scale used shall be marked out on the upper center of theenlarged part.1.7 尺寸标注Dimension Label尺寸标注用细实线绘制，尺寸数字字高与尺寸箭头大小一致：A4：2.5；A3：3.5。

Dimension label is to be made in continuous thin line, the arrow shall be in the same size as the digit height: A4：2.5；A3：3.5。

1.8 技术要求Technical Requirement技术要求书写采用细实线，字高：A4：2.8；A3：4。

Technical requirement shall be written in continuous thin line, character height: A4：2.8；A3：4.1.9 图中的表格Forms一般情况下，字高与尺寸标注一致。

如表格文字太多，可视情况而定。

Usually the character height shall be consistent with the dimension label. But if the text is too much, it may depend.1.10 表面粗糙度Surface Roughness代号中数字的方向必须与尺寸数字的方向一致。

对其中使用最多的一种代(符)号可以统一标注在图样右上角，并加注“其余”两字，且应比图形上其它代（符）号大1.4倍。

Digit in the symbol shall be in the same direction as dimension digit. And the most used symbol may be marked out in the right corner of the drawing, with remark of“Others”, and the size of 1.4 times larger than other symbols.1.11剖切符号及箭头Section Symbol and Arrow剖切符号：粗线；箭头：细线。
