In mechanical design, what is the significance of drawing 3D drawings?.
Product design is to determine the shape of the product and product function, but also the decisionThe most important part of the product quality, the product design work on the cost of the product alsoPlay a vital role. With the continuous development of computers, CAD technology is consideredComputer aided design has become an indispensable tool for designers. CAD technology is moving from 2D CAD to 3D CAD.Three dimensional design software, engineering and productionAnalysis, calculation, geometry modeling, simulation and experiment, drawing graphics and engineering numbersAccording to library management, generate design documents and other functions. 3D CADTechnology was born toIt has been widely used in the fields of machinery, electronics, architecture, chemical engineering, aeronautics and AstronauticsAnd energy, transportation and other fields, the design efficiency of products has been improved rapidly. Our country CADTechnical research,Great progress has been made in development and popularization,Product designComplete two-dimensional CADThe popularization of technology has ended the history of hand drawing,It has played an obvious role in reducing the intensity of manual labor and improving the economic efficiency.Advantages of 3D design software2.1.1Solid modeling of parts2.1.2The product is easy to modify2.1.3Generating entity assembly drawingTwo point twomouldCAD/CAMIntegrated manufacturingTwo point threeMechanicsCAEFunction application
For professionals, 3D map painting aims at first can visually see the three-dimensional geometry of parts, followed by analysis of the existence of the assembly interference, meets the design goal and the size, volume, stress analysis.For non professionals, they do not understand the specialized two-dimensional graph, and can help them understand the geometry of the object by means of the three-dimensional graph.
Advantages: first, look at the intuitive ah, design some complex parts and components, do not express several views.After assembly, the parts can be checked for size. And whether or not to interfere.Three, the software has powerful functions, such as calculation of volume, weight, force analysis and so on, these are two-dimensional software can not compare.
