Edges
Method 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-009 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. Single-segement lines are drawn on the grid of the surface. Each line is of a common length in three-dimensional space and is oriented normal to the surface. Run BC-009-001 uses a rectangular figure, which is nearly parallel to the paper plane. Separate pens for the horizontal and vertical (relative to the surface, not the paper) lines are used. Horizontal lines are drawn with a fresh pen. Vertical lines–beginning with those that correspond the edges of the paper–are drawn with a highly worn pen.
