Sketch is the primary mode of concept exploration and development in the early stages of design. In a global product development scenario, collaboration in the early fluidic stages could minimize design conflicts and enhance design understanding. In this work, the potential modalities of interactions among the collaborating designers in early stages using 3D articulated sketch based concept models are proposed. Depending upon the spatio-temporal characteristics, issues related to the hardware, software and network infrastructure in four possible collaboration scenarios are identified. It is argued that the 3D sketching techniques, earlier developed for haptics-enabled, articulated, conceptual designs, can be extended to support design collaboration using evolving concept sketches. The attributes of the 3D sketches and the requirements of the different collaboration scenarios seem to have an implicit and synergistic relationship. Results of initial experiments using TCP/IP based view sharing and interaction on an articulated 3D concept-sketch for elemental collaboration exercises are also reported.
