Research of sketch-diagram relationship with representation in holl and eisenman designs

From past to present when the progress of architectural design medium continuum have been researched; it has been observed that the geometrical language used in design have become abstract more than ever before within improvements and transformations particularly in the last twenty years at the field of information and technology. The image of the design idea, which is very important to dialate with other ideas need to be visualized, represented and evaluated with its all possibilities in a flow of determined thinking system since the time it falls in the mind. At the same time this current situation signifies that the architecture is in interested in the discovery of the one which never exist instead of the cuase-affect which the other disciplines are bound to and problematize its thinking through the happenings, conditions, facts through the design process. This at the same time concieves that the architectural design thinking need to be cognitive mental processes which in the reason that the idea also needs to carry information which is improvable and sustainable The architectural design process refer more about the events, actions and happenings of the idea attached to the form at time which the idea have been started to represent. The dialogue between the space and form however has shown that in traditional concepts that they are acting in different time intervals, today's contemporary represantation media defines this situation with its limitless posssibilities as simultaneous intervals. In this meaning, it signifies that the forms which are designed in abstract geometrical language are becoming more copmplex and distinctive. As a result t the distinction in represatation platform carries forward the sketch and the diagram as the tools for communications.
