5 Title block 标题栏(GB/T 10609.1—1989)
(批准) (审核) (工艺)  (材料标记) (单位名称)  (图样名称) (图样代号) (重量) (比例) (标记) (更改文件号) (签名) (阶段标记) (共 张) (第 章) (日期) (设计) (标准化) (处数) (分区) (存储代号) (校核) (班级) (日期) (校名) (图名) (材料)  (比例) (学号) (图号) (审核) (设计)  (共 张) (第 章) 学校的制图作业中常采用简化的标题栏,建议采用推荐的尺寸与格式

6 Scale 比例(GB/T 14690 — 1993) The size of the drawing 图形尺寸
The size of the object 实物尺寸 Originality scale 原值比例 1:1 Down scale 缩小比例 (1:1.5) 1:2 (1:2.5) 1:3 (1:4) 1:5 (1:6) 1:1×10n (1:1.5×10n) 1:2×10n (1:2.5×10n) (1:4×10n) 1:5×10n (1:6×10n) Enlarged scale 放大比例 2:1 (2.5:1) (4:1) 5:1 1×10n: ×10n:1 (4×10n:1) ×10n:1 英国比例

7 Lettering (Style) 字体(GB/T 14691—1993)
Chinese characters should be the “Fang Song” 汉字为长仿宋体 The font for all characters can be in italic font 数字、字母均为斜体 英国字例

8 Line styles 图线(GB/T 4457.4—2002) Description Line example Width Usage
图 线 名 称 Line example 图 线 型 式 Width 图线宽度 Usage 应 用 举 例 Continuous thick line 粗实线 d To indicate visible outlines,edges可见轮廓线,可见棱边线 Continuous thin line 细实线 d/2 For fictitious outlines, dimensions, projection hatching and leader lines, also for the outline of coincidence section, root of thread 尺寸线及尺寸界线、剖面线、重合断面的轮廓线、螺纹的牙底线及齿轮的齿根线、引出线等 Irregular(continuous thin )line 波浪线 Part sectional boundary lines or to terminate a part view, and for short break line 断裂处的边界线、视图与剖视的分界线 Continuous thin straight line with intermittent zigzag 双折线 To show a break on an adjacent member to which a component is attached 断裂处的边界线 Thin dashed line 细虚线 Hidden edges, hidden outlines. (Long line=12d, granularity=3d) 不可见轮廓线,不可见棱边线 (画长12d,短间隔长3d) Thick dashed line 粗虚线 Shown can be made surface-treatment. (Long line=12d, granularity=3d) 允许表面处理的表示线 (画长12d,短间隔长3d) Thin long dashed dotted line 细点画线 Axis lines, symmetrical center lines, etc. (Long line=24d, granularity=6, dot=3d) 轴线、对称中心线、分度圆(线)、剖切 线、孔系分布的中心线等(长画长24d,短间隔长3d,短画长=3d) Thick long dashed dotted line 粗点画线 To indicate a cutting plane for sectional views. (Long line=24d,granularity=6, dot=3d) 限定范围表示线(长画长24d,短间隔长3d,短画长=3d) Thin long dashed double dotted line 细双点画线 To indicate adjacent parts alternative and extreme positions of moving parts, also to indicate imaginary line (Long line=24d,granularity=6, dot=3d) 相邻辅助零件的轮廓线、可动零件的极限位置的轮廓线、中断线等(长画长24d,短间隔长3d,短画长=3d)

9 Line styles 图线(GB/T —2002) The example of drawing lines manipulate 图线的应用举例 Visible edges and outlines, continuous thick line 可见轮廓线 粗实线 Center line, thin dashed dotted line 对称中心线 细点画线 Hidden edges, thin dashed line 不可见轮廓线 细虚线 Dimension line, continuous thin line 尺寸线 细实线 Axis line, thin dashed dotted line 轴线 细点画线 Boundary between view and section view, continuous thin irregular line 视图和剖视分界线 波浪线 Extension line, continuous thin line 尺寸界线 细实线 Imaginary line,long dashed double dotted thin line 相邻辅助零件轮廓线 双点画线 The broken part, boundary, continuous thin straight line with intermittent zigzags 断裂处的边界线 双折线 英国图例

10 Line styles 图线(GB/T 4457.4—2002) The example of center line 中心线的画法举例 请
The center line should connect with the line segment 中心线应是线段相交 The end point can't be dotted 首末两端不应是短画点 There is no room in the circle center, and can't be dotted 圆心不应是短画点或间隙 Too long 超出轮廓太长 Should leave some space 2 ~ 5mm 超出轮廓2 ~ 5mm Should be longer than the segment 应超出轮廓线外 The center line of small circle can be replace by continuous thin line 较小圆中心线可 以用细实线代替 Should be a short line, not a dot 应是短画点, 而非圆点 Correct 正确 Wrong 错误 Small circle 较小圆 The example of center line 中心线的画法举例

11 Line styles 图线(GB/T 4457.4—2002) 正确 错误
虚线与粗实线相 接处应留出空隙 虚线与虚线相 接处不留空隙 正确 错误 The example of drawing lines manipulate 图线的应用举例 请点击鼠标左键显示后面内容

12 Dimensioning 尺寸注法(GB/T4458.4—2003)
1. Basic rules 尺寸标注基本规则 尺寸数字在尺寸线上方或 左方, 字头向上方或左方 尺寸界线 尺寸箭头 尺寸数字 尺寸线 尺寸界线伸出2~3mm 小尺寸在内 大尺寸在外 尺寸线与轮廓线及其他 尺寸线的间距为6~8mm
