Recently, in the research field of combined architecture and structural design, the idea of a so-called research engine has been developed. During its development, initially the intention was to develop a design-support tool, however, it now becomes clear that it may serve as a general framework for several applications. In this paper the new possibilities for the applications will be presented. As a result, a birdis-eye view is developed on a set of applications that are often presented separately and without a larger framework in literature. In conclusion, several applications used for CAAD and CASD (Computer Aided Structural Design) can be seen as derivatives of a research engine. The other way round, the research engine can be modified and new applications may result.
