In Taiwan, the software, AutoCAD which is developed by Autodesk Inc., is widely employed in architecture designing and construction applications. Basically, the drawings generated with AutoCAD are designed and sketched in 2-dimension. Those 2-dimensional drawings can hardly identify the relatively spatial relationships of the spatial objects shown in those drawings. However, with combining dots and lines to form a spatial object in 3-dimension, it is common in engineering drawing. In doing so, it usually increases the difficulty to modify the spatial object in 3-dimension. This thesis proposes a new approach to solve the difficulty. This thesis employs an object-oriented concept to establish the geometric data types and their related functions for the specified geometric objects to reduce the time for restoring the 3D spatial objects from the given 2D engineering drawings under the AutoCAD working environment. The developed information system can not only display spatial objects in 3-dimension, but also add the job scheduling for a construction project. The results shown in this thesis demonstrates the approaches used in the thesis can efficiently integrated spatial objects generated in 3-dimension and job scheduling to dynamically simulate the ‘real’ working processes. By the way, the quantities for each specified job can automatically located from the developed spatial information system in this thesis.
