Abstract

The invention provides a complex truss structure drawing method. The method comprises the following steps of: establishing a three-dimensional model of a truss by utilizing computer three-dimensional designing software; forming an engineering drawing through the software; inserting at least one three-dimensional view in the engineering drawing; determining an original point of a two-dimensional coordinate system or a three-dimensional coordinate system in a plan view of the engineering drawing; and giving a serial number of a part of each two-bar structure of the truss in the three-dimensional view of the engineering drawing, wherein the detailed statement of parts and components inserted into the engineering drawing comprises the following names: serial number, code name, name, quantity, material, length and coordinates. The length of each two-bar structure and coordinates of two ends of the truss are given, so that the positioning size of each node marked in the drawing is saved, the quality of drawing node drawings is reduced, and various views unavoidably drawn due to blocking are reduced; and the engineering drawing is simpler and more intuitive due to the three-dimensional view.

Description

technical field [0001] The invention belongs to the field of mechanical drawing, in particular to a drawing method for complex truss structures. Background technique [0002] At present, computer drawing is already a basic skill that engineering designers must master, and the use of computer 3D design software in the field of mechanical drawing has become very popular. The 3D modeling of the complex truss structure can be easily completed by using the computer 3D design software, and the 3D engineering view can be easily generated through the 3D model of the complex truss structure. The expression methods of national standard engineering drawings of mechanical drawing are mainly basic view, directional view, partial view, oblique view, section view, section view, partial section view, etc. It can be seen that the expression method of national standard engineering drawing of mechanical drawing is mainly view expression, The basis of its compilation is manual drawing. In the ...
