| Abstract |
This study demonstrates a software system that allows to build 3D models from architectural drawings. Using three different types of architectural drawings ? orthographic, facade, and perspective ? users can place and adjust geometric entities such that they align with the sketching lines in the input drawing. The focus of this study is to identify the desired interactions and interfaces for creating architectural elements in 3D virtual space. Unlike previous approaches in computer science that concentrate on building 3D models identical to the real-world scanned data, we view CAD interfaces as different shape language that transfer initial idea to digital data and strive to find interfaces that are intuitive to the architects. By analyzing the drawings first then finding the appropriate interactions, we present a user-friendly CAD interfaces that are extensible and universal. We also discuss the potential usage of our system as an intermediate framework that may integrate intelligent agent allowing automatic placement and propagation of geometric entities for 3D reconstruction. |
