Abstract: The present invention is a computer automated process for analyzing and interpreting engineering drawings in a digital format. The process is the recognition of symbols and graphics in any type of engineering drawings followed by an analysis of the relationship between the symbols and the graphical elements in the drawing to provide a meaningful interpretation of the drawings. The interpretation of the drawings can be carried out in a variety of ways including quantitative analysis of the drawings and/or three dimensional reconstruction of the drawings.

Abstract: A system for the distribution of electronic documents and information to multiple participants in a project hosting web site using a multiple account, multiple administrator platform such that each participant can distribute its files and or data to all other participants or selectively distribute its files and or data to selected participants. Each participant is provided with an individual platform which is linked to all other platforms on the server and which is self administered by each participant and which exists as a component of the project workspace. By maintaining a discrete and secure platform each participant receives its own individual copy of the electronic files and or data for document management, archival and internal circulation.

Abstract: A method of construction and installation of a self contained bathroom unit which is capable of installation in multi-storey buildings. The bathroom unit may be fabricated at a site remote to the site of installation and can be transported to the site as and when required. The bathroom walls are cast with conduits and spaces for light boxes and openings for windows and drainage. Hooks are also cast into the walls to enable the bathroom unit to be lifted to the desired location. The bathroom units are seated on a foundation which is laid for this purpose. The top slab of the bathroom unit can then be used as the formwork and a topping slab is cast in situ to form the floor of the next floor.

Abstract: A computer automated process for vectorizing raster images to create usable graphic files which can be manipulated by CAD software. The present process makes use of the geometric relationship among the graphic elements contained in the raster image and keeps the graphics elements as a whole during the process of vectorization. The present process not only recognizes the whole line, but also recognizes all the lines intersecting it. The process requires a central processing unit a of a computer programmed with the appropriate instructions to analyze lines found in the bitmap image, together with all intersections and shapes associated with the line in the bitmap image and process that information in accordance with predefined algorithms to create a usable graphic image file. As each line is recognized it is vectorized and it is then deleted from the bitmap image to speed up the process of vectorization.

Abstract: A computer automated method for identification, management and retrieval of engineering drawings in digital format where the central processing unit locates and identifies specific predefined textual and graphical information, relating to that drawing, in accordance with predefined algorithms. The textual information thus identified is then stored in accordance with predefined criteria to allow the engineering drawing to be identified and retrieved by reference to that textual information.
