DC-SQEM directly extracts medial meshes from oriented point clouds without first reconstructing a watertight surface or tetrahedralizing a volume mesh. It identifies candidate regions through local surface projections, fits medial spheres, and connects them into sheets and seams. On 93 ABC CAD models, it produced all 93 outputs with mean HD of 0.4203%; measured TER was 2.1505%, without a formal homotopy guarantee.
