. In this paper we present an application we developed for collaborative sketch sharing within a design process. We review the specific application development process and discuss the features of the application itself. The tool has been tested and used in a design studio setting between two universities located in different countries. We observed that it is suitable for architectural communication, and also allows monitoring of the sketch activity during the design process. This paper also describes application architecture and selected technologies. We have furthermore defined multiple groups of application requirements. Our self-developed application was proven to suit specified needs and overcame previously tested commercial tools.
