Merging Real and Virtual Construction Using Virtual-CAD
نویسندگان
چکیده
This paper presents the conceptual CAD system VCAD that supports construction of Virtual Technical Objects (VTO) in a three-dimensional stereoscopic environment using pre-defined virtual construction elements. From the newly created VTO, the CAD system automatically produces the drafts needed for the production of the real technical object. This approach contrasts considerably from the traditional construction process, where the engineer first produces drafts of his construction and afterwards 3D representations from these drafts. The VTO is created by joining basic elements taken from a library. The geometric properties of these elements are described as Geometric Cell Complexes, which were developed by Alexandroff et. al. in 1935 and refind for CAD purposes by Pitschke in 1996. A prototype of the VCAD system is presently implemented on a SGI workstation O2, specialising on Structural Engineering applications. It includes innovative Two-Handed Interaction techniques.

A Case Study of Applying Virtual Prototyping in Construction
The use of 3D computer-aided design (CAD) models to support construction project planning has been increasing in the previous year. 3D CAD models reveal more planning ideas by visually showing the construction site environment in different stages of the construction process. Using 3D CAD models together with scheduling software to prepare construction plan can identify errors in process sequenc...

The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...
متن کاملThirdspace: The Trialectics of the Real, Virtual and Blended Spaces
This article aims to redefine the concept of Thirdspace and make a trilateral relationship between the three concepts of real space, virtual space and the user. To do so, not only the concept of Thirdspace has to be redefined, but also a new understanding of virtual space as a relatively independent space is required. This three-sided relation requires a new understanding of the relationship be...
