This standard applies to metal hull drawings of civil ships and military auxiliary ships. Other ship hull system drawings, ship machinery and ship electrical drawings, in addition to their own characteristics. Can be used for reference
Parts not clearly specified in this standard should be drawn in accordance with the national standard "Mechanical Drawing". Terms
In this standard and hull drawings, the description of terms such as coordinate planes, hull surfaces and their lines is shown in Table 1. Table 1 Description of terms
Principal coordinate plane
Steel plane
Centerline plane
Hull centerline
Hull surface
External line
The coordinate plane composed of three right-angled axes on the ship, namely the base plane, the centerline plane and the mid-station plane
The horizontal plane passing through the intersection of the keel line and the mid-station line divides the body symmetrically and multiplies the axial plane perpendicular to the station
plane
The base plane and The intersection line of the super-surface plane is the vertical reference line. The intersection line of the centerline plane and the horizontal transverse plane does not include the design surface of the outer plate in the direction of the ship's outer shape, that is, the surface of the outer edge of the hull frame. The intersection line of the hull surface (including its extension) with the section plane. The intersection line of the centerline plane and the hull surface.

Continued Table 1
The intersection of the deck profile surface with beam arch and the transverse vertical plane at each auxiliary position is generally referred to as the maximum transverse surface
The reference line used to determine the installation position of the material component
The profile surface of the hull or the curvature pattern of the hull component
is the connecting line of the arc tangent points formed when the angle is folded (the dividing line made at the turning point when the wall plate is extended
).
When drawing the sample with the connecting line of points
, the basic surface specified in Table 2 should be adopted. Table 2

If necessary, the size of the basic format in Table 2 can be extended, and the extension amount shall be increased along the short side according to the integer multiple of the shortest length of the selected basic format, as shown in Figure 1. The width of all formats shall not exceed A 0 The width of the format. 2.3 Drawing border format
