Reliability And Availability

A 3D traffic environment build platform based on UC-win/Road is developed by discussing the advantages, functional integration of software in the platform, and the construction procedures of 3D environment. The procedures includes determining overall dimensions and textures of the models by close-up photography and remote sensing images, drawing traffic signs and road markings by CorelDRAW, making model maps by Photoshop, modifying models by 3Dmax and 3D Model Conversion Tool, adding models through three approaches in UC-win/Road: configuration of models, construction of road appendages, editing road section. In this paper, the construction procedure of buildings and road signs and the 3 views building method of terrain patch are concluded, and the example of reconstructing the traffic environment of from the Tianningsi Bridge to Fuxingmen Bridge in Beijing is given to demonstrate the reliability and availability of the platform in China.

Product Definition

The ASME Y14.41-2003 standard for Digital Product Definition Data Practices provides for representation of design data as an entirely digital package. One central requirement of the standard is storage of all design content, especially annotations, directly in the 3D model. Companies maintaining a library of models and drawings in their chosen CAD system will benefit from being able to quickly and reliably transfer drawing annotations into 3D models. This paper describes the design and development of a prototype conversion tool that will be capable of automatically converting existing drawing annotations into ASME Y14.41-2003 compliant 3D model annotations. The paper covers the mathematical formulation used for transfer of annotations from the drawing to the 3D model and the abstract software development model for the base classes and conversion algorithm. The paper presents examples for how the conversion tool was implemented within a commercial CAD system.

Content-based retrieval is particularly important for exploiting company model databases and online catalogs. To allow the identification of reusable part models possibly fitting with the product under development, methods for the similarity assessment between shapes should be provided in terms of both global and partial shape matching. In this perspective, this paper proposes a method directly working on B-rep models for 3D model retrieval, which does not require any model conversion to triangular meshes and in addition to global and partial matching allows the identification of components that may likely be assembled with a given model.

Layer Problem

Fused deposition modelling (FDM) is a process of joining materials based on material entrusion technique to produce objects from 3D model using layer-by-layer technique as opposed to subtractive manufacturing. However, many challenges arise in the FDM-printed part such as warping, first layer problem and elephant food that was led to an error in dimensional accuracy of the printed parts especially for the overhanging parts. Hence, in order to investigate the manufacturability of the FDM printed part, various geometrical and manufacturing features were developed using the benchmarking artifacts. Therefore, in this study, new benchmarking artifacts containing multiple overhang lengths were proposed. After the benchmarking artifacts were developed, each of the features were inspected using 3D laser scanner to measure the dimensional accuracy and tolerances. Based on 3D scanned parts, 80% of the fabricated parts were fabricated within ±0.5 mm of dimensional accuracy as compared with the CAD data. In addition, the multiple overhang lengths were also successfully fabricated with a very significant of filament sagging observed.
