Drawings 1, drawing specifications Engineering drawings are drawn in strict accordance with the relevant national architectural drawing specifications, and all drawings are required to be expressed in the same way. 2. Drawing catalogue The drawing catalogue of each major is compiled with reference to the following order: architectural specialty: architectural design description; Unified description of architectural design; Unified description of building structure; Building location map; Plan; Elevation view; Introduction; Stair details; Architectural details; Door and window details. Structural specialty: general description of structural design, foundation layout, number of shear walls, shear wall table, beam reinforcement diagram, plate reinforcement diagram, stair diagram, detailed drawing 3 and drawing depth. The engineering drawings shall meet the legend depth and special requirements provided by the owner. 4.

SHX 5.0mm. 0.8 dimension label Simpelx.shx3.0mm 0.8 Note: The scale of Chinese and western languages is set to 1: 0.7, and the description text should generally be located on the right side of the drawing. Word height is the height after printing. Characters in other symbols should be automatically generated by Tianzheng, and the height should be set to 3.5. 5. Drawing version and modification mark 5. 1. 1 construction drawing version number The first drawing version number is 0; Version number of the second drawing is1; The version number of the third drawing is 25.1.2; The first drawing version number is a; The version number of the second drawing is B; The third drawing version number is C 5.2 drawing modification mark drawing modification. Simple or single modification still uses change orders. 6. Drawing width 6. 1 Drawing adopts four standards: A0, A 1, A2 and A3, with A 1 Drawing as the main standard. The drawing frame file is placed on the company's computer network server (the specific location is S: \ dept. share \0 1 the construction drawing is the 2009 construction drawing summary of Haikou Binjiang Dijing Project \ public \ drawing frame (2008 [1] .02.01) _ t3.dwg). Drawing type Drawing width (mm) Drawing height (mm) Remarks A 01189 x 841841x594a2594x420A 3420x297A 4297x210 are mainly used for catalogue and change. 6.3 Drawings used by professionals shall not exceed two formats (except A4 format used in catalogues and tables). 6.4 The commonly used drawings are as follows. It is not recommended to have more than three proportions in the same picture. Common proportion Table 3 Common proportion 1: 1,1:2; 1: 5， 1: 10， 1: 20， 1: 50， 1: 200，65438+ 1: 30， 1: 150， 1: 250， 7. Layer and file exchange format 7. 1 The purpose of using layers is to organize, manage and exchange entity data of CAD graphics, and control the screen display and printout of entities. Layers have properties such as color, line type and state. 7.2 Hierarchical organization can adopt different methods according to different purposes, stages, entity attributes and users, but it should be logical and easy to operate. Various entities should be placed on different layers, for example, in the plan, the axis and the third dimension should be marked in layers; Kitchen and bathroom sanitary ware, furniture, etc. Represented by a separate layer; Cartographic symbols should be set according to the layers generated by the sky, and it is not appropriate to draw and transform the layers by yourself. 8. Supplementary explanation 8. 1 Common illustrations are in accordance with the Unified Standard for Architectural Drawing (GBJ 186), General Drawing Standard (GBJ 103-87) and Legend of Architectural Drawing Standard (GBJ 104-87) 8.2 Line width (unit: mm). All construction drawings are drawn with reference to the pen widths listed in the table below. Types of architectural drawing thick line 0.40 thick line 0.20 thin line 0. 10 When drawing with CAD technology, try to control the width of drawing pen with color, and try to use less lines with width such as PLINE, so as to speed up the graphic display and reduce the graphic files. In general, the thick line should be 2# color (yellow); 1# and 9# colors should be used for thin lines, such as 1# colors (red) and dotted lines for axes, and 8# or 9# colors (gray) should be used for details. It is not advisable to use too many colors for medium thick lines, such as 3# color (green) for markers, 4# color (sky blue) for doors and windows, 6# color (purple) for stairs and balconies, and 7# color (white) for characters. Structural specialty adopts object line width, 0.4mm for reinforcement, 0.3mm for other thick lines, 0.2mm for center line and 0.09mm for axis. 8.3 Symbols All kinds of drawing symbols should be drawn in the form of positive generation. When drawing with the graphic scale of 1: 100, the distance between two broken lines should be 100mm, which should be adjusted according to other graphic scales. 8.5 When drawing dimensions on the scale of 1: 100, the distance between the first dimension line and the shaft number is 750mm, and the distance between dimension line and dimension line is 800 mm In other graphic scale drawings, the distance between dimension line should be adjusted proportionally. For example, when the graph scale is 1: 50, the distance between two dimension line is 400 mm, and when the graph scale is 1: 20, the distance between two dimension line is160 mm. 8.6 elevation 8.7 drawing name (word height 10mm) 8.8 computer drawing building drawing initial setting text font definition: text aspect ratio 4.0 0.8 note: in CAD drawing, when multiple drawings use the same template, you can use layer manager to reduce workload and improve work efficiency when the template changes.
