This research instrumentalizes the deliberation on drawing in architectural representation, in order to criticize the way of seeing that is dominated by recent media technologies and power relations. This paper intends to search how the drawing, in particular line-making, is affected in this environment, and how to respond to it via alternative, manipulative, and creative tactics of vision considering drawing as a critical act. The dependency of line on visuality is criticized by alternative drawing practices of contemporary line-makers. Consequently, imaginative, creative and layered qualities of design thinking, representation and production can be uncovered. Originality in architecture lies in its virtual, hidden, unseen and unnoticed properties. Methodology selected is nourished by an argumentative method that is based on a system theory approach. A dialectical discussion is conducted utilizing some concepts such as visual-nonvisual, physical- virtual, material-immaterial, and temporal-permanent. Following a qualitative approach, unbinding the concept of line changing on a similar axis with digital mediums and tools, the conceptualization process of drawing from a historical point of view, questioning the new concepts that it relates to, and discussing the interaction of changes in line tools and representations constitute the path of this research. As a consequence, it may be proposed that prioritizing the unseen, minor or secondary characteristics of design issues and their dynamic relationships may reveal an alternative line-making practice.
