Description
Technical Field
The invention belongs to the technical field of intelligent manufacturing, and particularly relates to an industrial product 3D collaborative design system and a design method.
Background
As is well known, 3D is an abbreviation for three-dimensional meaning. Displaying 3D graphics in a computer is to display three-dimensional graphics in a plane. Unlike the real world, a real three-dimensional space, there is a real distance space. The computer only looks like the real world, so that the 3D graphics displayed on the computer are more vivid to the naked eye. The naked eyes have the characteristic that the size is large at near and small at far, and the stereoscopic impression can be formed. The computer screen is planar and two-dimensional, so that people can enjoy a three-dimensional image as a real object, and the two-dimensional computer screen is perceived as the three-dimensional image because human eyes generate visual illusion due to different colors and gray levels when the three-dimensional image is displayed on the computer screen.
Particularly for industrial products with complex structures, the planar two-dimensional graph cannot completely show the details and the internal structural relationship of the products, and the design of the industrial products is also limited to a certain extent. Statistics show that 70% of errors are generated in the design stage and 80% of errors are often found and corrected in the production or later stages in the development and production process of modern industrial products. The 3D has the outstanding advantages that the simulation design and user communication can be carried out on the product to the maximum extent, errors and requirement change are solved in the design stage as early as possible, the product development period is shortened, the production cost is reduced, and the enterprise market competitive advantage is improved.
On the other hand, the introduction of the collaborative design engine helps the industrial product design to establish a unified design standard, including layers, colors, line types, printing styles and the like, on the basis, all design professionals and personnel can design on a unified platform, thereby reducing errors, omissions, collisions and defects caused by unsmooth communication or untimely communication among the current professionals (and inside the professionals), really realizing the unicity of all drawing information elements, realizing other automatic modification at one place, and improving the design efficiency and the design quality.
In the prior art, an industrial product 3D collaborative design engine carries out online editing on an industrial product assembly relation and an import model based on a three.js rendering library, and can rapidly and simply complete industrial product 3D modeling; realizing visual combination of the assembly relation by using an assembly constraint technology based on a directed graph; optimizing the original large-range multi-frequency model rendering by using an event-driven 3D rendering technology to perform 3D rendering by using event operation as a drive so as to weaken the multi-frequency rendering change; the method comprises the steps of improving a measuring means for carrying out point selection ranging by taking an object as a reference by utilizing a scene measuring technology based on a camera plane, and realizing scene ranging by taking a multi-hypothesis plane as a reference; introducing a planar projection generation technology of a grid model, and performing point-to-surface planar projection on the 3D model; and a plug-in rendering engine based on event scheduling is utilized, and the multifunctional combination of the model assembly relation is realized on the basis of function improvement.
The method has the defects that only a single client service is provided, the requirement of the current internet cooperative operation cannot be met, and the learning cost is higher for non-professionals; on the other hand, since the assembly and construction of a single industrial 3D model cannot completely cover the production operation requirements in the industrial field, the combined engineering drawing of the 3D model and the actual production process becomes a technical defect to be solved urgently.
The difficulty and significance for solving the technical problems are as follows: at present, in the field of industrial product processing and manufacturing industry, for the early customer demand docking stage, the problems of long time period, unequal demand, defective product design and the like exist, so that the product sale period is prolonged, and the time cost is seriously wasted. The introduction of the industrial product 3D collaborative design engine builds a communication bridge between a client and a sales and design engineer, the client can carry out simple model editing according to the requirement through the existing product model of the engine, and the engineer assists in carrying out online design together, and finally a product drawing BOM list is generated and exported to guide the factory production. The industrial product design efficiency is improved, the product is rapidly produced and quoted, the sale period is shortened, the enterprise benefit is improved, the workload of engineers is reduced, and the repeated operation is avoided.
