2.Abstract: This paper mainly utilizes the methods of formula, isometric transform, cut and complement, extremes and analyzing special section to calculate the volume in solid geometry.
3.As to Model 1,we work out the spherical distance in solid geometry,it turns out that it only costs 10 8734 hours to fly from Beijing to Detroit,while 14 7793 hours by the original flight course,and at least 3 9095 hours is saved.
4.The peper analyzes the essentiality of developing the die CAD/CAM system with three dimension construedve solid geometry (CSO) technolosy, and discusses the methodology for building data structure of three dimension information of perts and their relationship with object-oriented analytics. The data structure can serve as the base of developing the die CAD/CAM system software.
6.Based on SolidWorks platform and with API as application programming interface and the type transformation and the general type transformation theory as basic theory of kinematics analysis the movement simulation of 3 D solid of mechanism can be realized through selecting and transforming mate feature of the mechanism and geometry information of components of the assembly, and using the tool of Visual C ++ language.
7.During the process of CAIP(Computer Aided Inspection Planning), the key problems include how to obtain tolerance data from draws and how to use these tolerance data to match 3 D geometry elements. This paper proposes a method to match 3 D geometry elements automatically with the associativity between tolerance information and 3 D solid modeling internal CAD database.
8.Based on Hele-Shaw flow model, methods of model integrated analysis were studied for injection molding parts with complex surfaces. The technological frame and executable steps were put forward,which estimate injection moulding in product structure in advance and add thickness attributes on CAE mesh model according to the CAD geometry surface when solid models of the parts with complicated surfaces were constructed.
9.The principal research achievements are as follows:(6) The infrastructure and development mechanisms of ACIS geometry engine are studied. The key technological issues dealing with the support of ACIS for the development of NC programming system are solved, which provides the sound basis for the development of MC machining programming system based on solid models.
10.Combining the ObjectARX development experience and using examples, This article introduces how to use ARX tool and system resources and how to call the AcBr and AcGe class libraries to access and extract the geometry information of the entity and sub-entities on a three dimensional part solid model ,also it explains the application of the two libraries on the development of the feature-based modelling system.
