The building design process becomes increasingly complicated every year, but employing digitised tools enables designers to consider diverse requirements for a project. For an architect, considering the relationships between objects in the building model is essential. These relationships are defined as conceptual ideas or specific requirements for a building and can be formalised as design constraints. Currently, design constraints are set by the user within the Building Information Modelling (BIM) tools with a limited number of constraint types. Besides identifying design constraints, the appropriate representation is needed because not all information can be intelligibly displayed. To address this, the thesis presents a semi-automated approach to identifying and representing design constraints. The identification process employs statistical analysis, and representation is based on a graph approach. The approach provides a tool to formalise design constraints according to the extracted design knowledge in the model. Afterwards, the graph-based representation is employed and allows one to select a design constraint and display its representation. The constraints identification and representation processes are tested for several types of geometric constraints. The proposed method increases the efficiency of the design process and guides better application and interpretation of design constraints with digitised modelling methods.     «
