Green Design Effectiveness for a Mini Automotive-Repair Facility
Published in Jacqueline A. Stagner, David S-K. Ting, Green Energy and Infrastructure, 2020
Interoperability: Assistance is given to members of the expanded project team. It can export and import data from the group (such as MicroStation Design File (DGN), International Finance Corporation (IFC), DraWinG (DWG), and Drawing interchange [X] Format (DXF)) is widely used formats.
Facilitating integration of computational design processes in the design and production of prefabricated homes
Published in Architectural Science Review, 2018
With the building's envelope previously established following discussions between stakeholders and planners, project work focussed on set up of the framework of the design domain's parts in relation to the whole. The framework of the whole was defined by grids and levels associated with ‘components’ built-in to the AEC CAD software, a tool categorized by Schodek et al. (2005, 184) as a ‘component based modeller’ (e.g. Autodesk Revit, Bentley Microstation, Graphisoft Archicad). After adjustment of grids and levels, ‘grouped’ modules – residential units, bathroom pods, clip-on balconies – were repeatedly copied into grid locations to facilitate parametric propagation of changes (Figure 1).

According to the different stages of 3D pipelines modeling, the urban pipeline visualization method can be divided into CPU and GPU intensive methods. Du and Zlatanova (2006) introduced the detailed geometrical modeling of 3D pipelines, in which spheres were used to eliminate the gaps between pipelines, as well as their superimposition. The software used included MicroStation and the Java edition of the MicroStation Development environment (JDML). Schall, Junghanns, and Schmalstieg (2008) presented a transcoding pipeline for on-the-fly creation of interactive 3D visuals from 2D geospatial sources. This innovation was subsequently used by Schall, Schmalstieg, and Junghanns (2010) for the modeling of underground utilities in augmented reality (AR) applications on mobile devices. He et al. (2011) stored a pipe network in an Oracle database, and dynamically visualized 3D pipelines using the secondary development of ArcObject. Döner et al. (2011) presented the 4D (space + time) management and registration of utility networks using a spatial DBMS, and visualized pipelines in CAD and GIS applications. Becker, Nagel, and Kolbe (2013) proposed a new geospatial information model of multi-utility networks, with the plan to use multiple LODs and alternative geometric elements, such as sweep geometries, to represent pipelines. Guerrero, Zlatanova, and Meijers (2013) introduced a variety of strategies for obtaining vector information from a database, and identified the best strategy for creating 3D pipes for 3D visualization. In these previous studies, to decrease the network transmission load, the 3D pipelines were mainly generated by the CPU. However, pipeline modeling is CPU-intensive, and the overhead between the CPU and GPU cannot be alleviated.

The bridge geometry was surveyed by MNDOT staffs and its digital model was reconstructed as a 3D model using the commercial software Microstation. The bridge has three lanes with 12 piers aligning in the west–east direction as shown in Fig. 1. Due to the difficulty in surveying, the foundation and piling system of the bridge piers are not considered in this study. Only the exposed parts of the piers from water are considered as shown in Fig. 5.
