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

The drafting method of complicated truss-frame structure

Technical field

The invention belongs to the mechanical drawing field, relate in particular to a kind of drafting method of complicated truss-frame structure.

Background technology

At present, computer graphics has been the basic skills that the project planner must grasp, and the Computerized three-dimensional design software is very universal in the use in mechanical drawing field.Utilize the Computerized three-dimensional design software to finish the three-dimensional modeling of complicated truss-frame structure easily, the three-dimensional model by complicated truss-frame structure is easy to generate three-dimensional engineering view.The expression way of mechanical drawing national standard engineering drawing mainly is basic view, to view, partial view, oblique view, cut-open view, sectional drawing, partial sectional view etc., as can be seen, the expression way of mechanical drawing national standard engineering drawing mainly is that view is expressed, the basis of its establishment is manual drawing, in the actual design to some complicated truss-frame structure since in view serious shielding, level is not really distinct, joint form is various, do not have certain rule, make mechanical drawing national standard expression way can not simple and directly finish expression fully.

Summary of the invention

Expression way at existing machinery drawing national standard can not simple and directly be finished expression fully to some complicated truss-frame structure, of the present inventionly provides a kind of method of expressing complicated truss-frame structure.

The present invention by the following technical solutions, its step comprises:

Set up the three-dimensional model of truss;

Form the engineering drawing that comprises at least one 3-D view of truss;

In the plan view of engineering drawing, determine two-dimensional coordinate or three-dimensional coordinate initial point;

In the engineering drawing 3-D view, provide the part sequence number of each two power bar of truss;

Comprise following title in the parts list in 3-D view: sequence number, code name, title, quantity, material, length, coordinate.

The invention has the beneficial effects as follows, express the structure of truss with the length of each two power bar of truss and the coordinate at two ends, finish the location of each two power bar, can save the location dimension that marks each node in the drawings, reduced the quantity of drawing node diagram, reduced owing to blocking the multiple view of haveing no alternative but draw, simultaneously, owing to provided at least one 3-D view, it is simpler and more direct, directly perceived that engineering drawing is expressed.
