Abstract: Reciprocal frames (RF) consist of elements which mutually support each other. The development of surface-related reciprocal frames is very dynamic. There are few architectural issues related closer to geometry, and demanding more work from innovative architects. The present study observes the regularities in different occurrences of RFs from medieval wooden slabs to digitally designed and fabricated amorphous structures. Our purpose is to analyse the main reasons why we should apply RF, and to describe the varicosity of symmetries which it implies. Furthermore, we examine the development process of more and more complex applicable geometries.
