This paper presents the design of a software framework for conceptual design. It develops an approach to mapping an evolving symbolic description of design into a geometric description. The distinct elements of the symbol-form mapping are (a)deriving spatial relationships between objects as a consequence of the functional relationships; (b) instantiating alternative feasible solutions subject to these relationships; and (c) presenting the evolving description of geometry. Computational support for each of these elements is provided within a conceptual design framework. The paper presents components of the framework, explicitly identifies interactions between these components, and explains how these interactions are developed into an integrated framework. It presents the rationale for the design decisions made in the framework. An example is presented to clarify the approach adopted. The applicability of the approach is then discussed. Finally, the paper explains who principles of software design are very relevant in an engineering design context.
