5.4.5 Outgoing:

The outgoing lines are all horizontal thin lines with a width of 0.25, and the text description is written above the horizontal line. At the same time, several leads in the same position should be parallel to each other.

Figure 5.4.5 Lead-out wire

Figure 5.4.5 * * * Same outgoing line

Size:

The extension line and dimension line shall be drawn with thin solid lines, with 2mm at both ends.

The starting and ending symbols of the size are drawn with thick lines, the inclined direction is 45 clockwise with dimension line, and the length is 2 ~ 3 mm ..

Elevation:

0. 15 2.80

The elevation symbol is represented by an isosceles triangle. Where there is no horizontal line at the sharp corner of a triangle, it is also used in plan view and top view, as shown in figure (1). Where there is a horizontal line, the horizontal line should refer to the height of the elevation of the section to be marked, and the sharp angle can be up or down. Take m as the unit

5.4.8 Connection symbols:

The connection symbol indicates the parts to be connected with a dotted line, and the connection number should be indicated with capital letters at both ends of the dotted line near the edge of the pattern. Two connected patterns must be numbered with the same letter.

Slope:

6. Layer

6. The purpose of using layers in1is 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.

6.2 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, and the detailed dimensions of doors and windows should be expressed in layers. Kitchen and bathroom fittings and their labels are represented by separate layers; Dimensions such as elevation should also be expressed independently and hierarchically.

6.3 When drawing with CAD technology, try to control the width of the drawing pen with color, and try to use less lines with width such as PLINE, so as to speed up the display of graphics and reduce graphics files.
