In this project, we combine constraint satisfaction techniques with research into intuitive design support to build an intelligent CAD tool for architects. Cases from former designs are combined within a new context to form an appropriate solution for a new task. Constraints provide the adaptation knowledge for cases and are used to define the combination of cases. Furthermore, architecural guide-lines and laws are modelled using constraints, i.e., constraints are generated according to the current state of the design. Constraints can be fixed are soft. A soft-constraint expresses a designer's preferences rather than an restriction imposed by law or physical principle. The system later activateds as many high-priority preferences as possible. Linear programming methods allow interactive exploration of solution spaces in order to find best solutions interactively.
