With a TwistMethod BC begins with a surface, which is then parsed, traced or divided to eventually inform marks on paper after undergoing some form of projection. Series BC-010 assumes a parallel projection at the onset of the surface creation by aligning and scaling the input surface to correspond to the dimensions of the edge of the paper. A figure–unaligned and nonparallel to the surface edge–defines the end of the surface and informs its curvature. Lines made up of straight segments are drawn vertically and horizontally within the space of the surface. Every other segment in each line is of a common length in three-dimensional space and is oriented normal to the surface. Intermediate segments connect the end of these segments to the start of the next segment, forming a continuous line across the surface. Run BC-010-001 uses a circular figure and uses a separate pen for the horizontal and vertical (relative to the surface, not the paper) lines. Horizontal lines are drawn with a fresh pen. Vertical lines–beginning with those that correspond the edges of the paper–are drawn with a slightly worn pen.
