In the late 1990s, the application of CAD technology developed in depth. One was the development of 3D design software using 2D drawing CAD software, and the second was The component design is developed to the whole machine design, and the third is the development from the stand-alone operation to the application PDM technology integration operation. However, at present, quite a number of enterprises are still stuck in the “picture version†stage, and have been using two-dimensional drawing software. This is superior to traditional manual drawing, but with the complexity of some engineering projects, two-dimensional The drawbacks of the software gradually emerged. Although many companies have used 3D design software, and many 3D design software has a good function for the entire product design process, as well as optimization analysis, calculation, etc., and also a series, general, component (module) library, provide a database work platform However, due to the complexity of its use, 3D design software is difficult to popularize like 2D design software. Therefore, solving the transformation of the design platform from two-dimensional to three-dimensional, and facilitating the integration of CAD and PDM to achieve the informationization of design and manufacture is an urgent problem to be solved. Because Autodesk's AutoCAD has a long-term application history and extensive foundation in China, and the Inventor 3D design software launched by Autodesk, it has good operability and ease of use, and good compatibility with 2D CAD software. At the same time, it can seamlessly connect with Autodesk's product data management system Productstream. Therefore, Inventor is a three-dimensional design software, which has positive significance for realizing 3D design and information management of products. 2, Inventor main function overview Compared with other similar products, Inventor has a simple user interface, fast 3D running speed and outstanding display coloring. Its main functions are as follows: 2.1. Inventor is a feature-based 3D solid simulation system In Inventor, there are two main features, one is a three-dimensional feature generated by a sketch, and the three-dimensional feature generated by the sketch is generated by sketching. The other is placed features (such as shelling and chamfering), and the placed features are created by providing position and parameters. In addition, work features can be used to construct and establish relative relationships between various features. 2.2.Inventor assembly method and adaptive assembly technology There are three ways to assemble in Inventor. The first way is to design all the 3D solid parts first, and then assemble these 3D solid parts one by one in the assembly file. The second way is that the part can be temporarily constructed during the assembly process, that is, the designer can start from an assembly file, because it is necessary to construct a new part during the assembly process, and work in the assembly environment can be enhanced for Intuitive and visual images of existing physical parts and the requirements of new parts [1]. The third way is the combination of the first two methods, which can make some physical parts in advance, then start an assembly file, assemble the parts, and then continue to construct new parts. When an assembly is completed, the system can generate a bill of materials to connect to other repositories. Adaptive technology allows the user to easily define the size and shape of the part without any unforeseen assembly relationship problems. If the proposed problem can be solved, its system will automatically resolve and ignore how the problem is implemented. Autodesk Inventor's adaptive assembly allows you to define relationships for associated parts without parameters or equations. Adaptive assembly is independent of order and the defined relationships are not limited by the relationship. 2.3. Autodesk Inventor project files and multi-user environment Autodesk Inventor provides a project for managing the storage location and current state of files in a product design. Users can define multiple projects themselves, but only one currently active project at a time. Only the file you are in is in the current project. Each project is in the form of a file that allows the product design in Autodesk Inventor and the file system of the computer to be largely independent, providing a unified framework for the design team in a networked environment. The project file provides Inventor with a tool for team design work in a multi-user environment, enabling parallel design, personal workspace, and avoiding conflicts. Its multi-user environment has two modes of sharing and semi-isolation. In the shared mode, each user directly operates on the public data file, and the edited file in the semi-isolated mode is copied from the server to the personal space, and the unreplicated file can continue to be referenced by the user on the server. 3, the experience of using Inventor 3.1. Inventor is easy to learn and easy to use After a month or so of self-learning and exploration, you can reach the level of skilled operation software to complete the design task. This is mainly due to the fact that Inventor is easy to operate, easy to learn and easy to use.
