With Pro/Toolkit of Pro/E and ADO(ActiveX Data Object) database technology, part parametric CAD system is developed and an successful instance is introduced in the paper. In the CAD system, interface between Pro/E and VC++6.0 is created correctly using Pro / Toolkit and user interface for part parametric designing can be achieved by means of dll( dll dynamic link) library built in VC++6.0 .Meanwhile ADO database is applied in the CAD system to manage all part parameters and thus part revising and updating can be realized quickly. The developing method in the CAD system not only is applicable to typical mechanical part designing but also be helpful to establishing standard part library.

Abstract Virtual prototyping is a relatively new field which is significantly changing the product development process. In many applications, virtual prototyping relies on virtual reality tools for analysis of designs. This paper presents an architecture for a virtual prototyping system which was created for the analysis of automotive interiors. This flexible and open architecture allows the integration of various virtual reality software and hardware tools with conventional state-of-the-art CAD/CAM tools to provide an integrated virtual prototyping environment. This architecture supports the automatic transfer of data from and to parametric CAD systems, human modeling for ergonomic evaluations (first person and third person perspectives), design modifications in the virtual environment, distributed evaluations of virtual prototypes, reverse transfer of design modifications to the CAD system, and preservation of design intent and assembly intent during modifications in the virtual environment.

Using Visual Basic as the development platform, the agricultural products traceability code system was constructed based on the PDF417 two-dimensional bar code technology through the embedded c++ dynamic link library (DLL) in the paper. The system implemented the expression of the related information for agricultural products origin, agricultural products, certification types, agricultural products processing enterprises, production date, shelf life of agricultural products and so on. Through the effective traceability of agricultural products, the requirements of the consumers to agricultural product quality were satisfied by the system.

Abstract Pluvial flooding in urban areas is characterized by a gradually varying inundation process caused by surcharge of the sewer manholes. Therefore urban flood models need to simulate the interaction between the sewer network and the overland flow in order to accurately predict the flood inundation extents. In this work we present a methodology for linking 2D overland flow models with the storm sewer model SWMM 5. SWMM 5 is a well-known free open-source code originally developed in 1971. The latest major release saw its structure re-written in C ++ allowing it to be compiled as a command line executable or through a series of calls made to function inside a dynamic link library (DLL). The methodology developed herein is written inside the same DLL in C + +, and is able to simulate the bi-directional interaction between both models during simulation. Validation is done in a real case study with an existing urban flood coupled model. The novelty herein is that the new methodology can be added to SWMM without the need for editing SWMM's original code. Furthermore, it is directly applicable to other coupled overland flow models aiming to use SWMM 5 as the sewer network model.

Mechanical Design Handbook oriented standard part library system of jaw clutches is developed based on SolidWorks. The system consists of three elements, namely a dimension parameter database, a user interface, and a modeling function module. The jaw clutch dimension parameter database is designed based on national standards. According to designers’ thinking habit, a visual user interface is customized to make easy use of the dimension parameter database. The data relationship between the modeling function module and dimension parameter database is established by using parametric program driven method. The jaw clutch standard part library with characteristics of friendly user interface and expansible database is easy to use. The approach adopted in the paper can be used to develop other general 3D standard part library on SolidWorks.

Some techniques of controlling remotely the digital storage oscilloscope are proposed including VISA, VXIplug&play drivers, TVC and IVI-COM drivers. By means of TekVISA, several application development environments can be used to develop functions of the digital storage oscilloscope. The programming language of Visual C++ is used to develop software. With the help of TekVISA and the dynamic link library, remote control to the digital storage oscilloscope through network is completed. All operations to the digital storage oscilloscope including parameters setup, data acquisition, waveform acquisition and storage, data processing are implemented in a remote place. The results show that the techniques of remote control are convenient and efficient and fit for experiments of scientific research and practical projects.

In this paper, a series of interface tests on interaction approach for the generation of geometric shape designs via multi-sensory user interface of a Virtual Reality (VR) based System is presented. The goal of these interface tests is to identify an effective user interface for VR based Computer-Aided Design (CAD) system. The intuitiveness of the VR based interaction approach arises from the use of natural hand movements/gestures, and voice commands that emulate the way in which human beings discuss geometric shapes in reality. The focus of this paper is on determining a set of effective interaction approaches by using the combinations of auditory, tactile, and visual sensory modalities to accomplish typical CAD tasks. In order to evaluate the proposed interaction approach, a prototypical VR-CAD system is implemented. A series of interface tests were performed on the prototypical systems to determine the relative efficiency of a set of potential interaction approach with respect to specific fundamental design tasks. The interface test and its results are presented in this paper.
