Sandback similarly reduced sculpture and drawing to their most elemental geometric forms, using minimal means to define space and contour with extraordinary precision. His work shares McEwen's emphasis on the conceptual weight of a single unbroken line and the monumental presence of simple geometric outlines.

Mangold repeatedly explored circular and elliptical forms rendered in flat monochromatic tones on shaped supports, directly paralleling McEwen's fusion of geometric precision with minimalist restraint. His practice similarly elevates a single geometric contour into a contemplative and deliberate visual statement.

Lohaus worked with graphite and industrial materials to create works of stark geometric simplicity and understated monochromatic mood, closely echoing McEwen's combination of raw drawing materials mounted on rigid industrial supports. His conceptual approach to form and measurement aligns strongly with the meditative precision of this piece.
