The paper describes CKB (Construction Kit Builder), a
computational design environment based on defining, then working
within, a system of components and rules for their placement. In
construction details, the components and placement rules are
standard; in less routine design tasks they are not. CKB uses a
constraint-based, object oriented, system architecture to
provide two levels of design support. At the higher level,
designers of technical systems use CKB to specify components and
rules for their positioning. At the lower level, building
designers use CKB to lay out components of these systems. last
