Abstract Enhancing a given architectural free-form shape to feasibility often involves the approximation by a developable surface, either as an intermediate step for further planarization or to build single curved panels. Over the last years, many theoretical approaches have been presented that require optimization frameworks or mathematical equation solvers that are not readily available for the practitioner.

The new approach we present in this work takes a family of curves and constructs strips of conical and cylindrical panels between them. Two panels touch along a common ruling, which almost follows the conjugate direction. Planarization and development of the strip into the plane follow naturally. An easy, step-by-step algorithm that can be scripted in any CAD software is presented, as well as examples from architecture.
