5.2 graphs face revises number
Blueprint is revised can distinguish with version date, revise every time number must be made in modification place, make clear version date.
Simple or onefold revise use modificatory requisition as far as possible.
6, blueprint width of cloth
6.1 blueprint pursue use A0, A1, A2, A3 4 kinds of standards, give priority to with A1 blueprint.
Blueprint measurement standards is expressed 2
Width of blueprint sort blueprint (Mm) blueprint height (Mm) remarks
A0 1189 841
A1 841 594
A2 594 420
A3 420 297
A4 297 210 basically is used at catalog, change, revise etc
6.2 special need can be used by dimension of lengthen of modulus of long side 1/8 (unite standard) by housing cartography.
The blueprint that a 6.3 professional place uses, unfavorable two kinds of over width of cloth (catalog and form place use) of except of A4 width of cloth.
6.4 blueprint scale
Commonly used blueprint is as follows, in paper of same Zhang Tu, unfavorable appear the scale of 3 kinds of above.
Commonly used scale is expressed 3
1:1 of commonly used scale, 1:2;1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:500, 1:1000
Usable scale 1:3, 1:15, 1:25;1:30, 1:150, 1:250, 1:300, 1:1500
7, graph layer and file trade pattern
The screen that the 7.1 ends that use graph layer are the hypostatic data that is used at organization, management and commutative CAD graph and control substance shows and printout. Graph layer has the property such as form of color, line, condition.
The utility with different basis of organization of 7.2 graphs layer, phase, hypostatic attribute and use object can adopt different method, but should have certain logic, facilitating operation. Of all kinds substance should be placed go up in different graph layer.
8, compensatory specification
8.1 commonly used legend
Cartography of comply with housing unites a standard (GBJ186) ,
Standard of general drawing cartography (GBJ103-87) ,
Standard of town planning cartography (CJJ/T97-2003) ,
Building cartography standard (GBJ104-87) legend regulation.
8.2 line width (unit: Mm) , all construction blueprint, all consult the watch lists a broad scale 4 times.
Blueprint line width is expressed 4
Plan of structure of phyletic building plan is electric the graph warms to catchment
Thick wire 0.50 0.60 0.55 0.60 0.60
In thick wire 0.25 0.35 0.35 0.40 0.40
Filament 0.15 0.18 0.20 0.20 0.20
When using CAD technology plot, use color as far as possible (COLOR) the width that controls plot pen.
8.3 symbols
8.3.1, axes. Axes is round all answer with scale of fine solid line. Round diametical 8mm.
8.3.2, index symbol, the circle of index symbol reachs a diameter to all answer with scale of fine solid line. Round diametical 10mm.
8.3.3, detail drawing: Detail drawing symbol with scale of wide solid line, the diameter is 14mm.
8.4 derivative lines
Derivative line uses a level to 0.25 wide filament, diagonal becomes 45º , literal specification all writes Wu Shuiping over the line.
