Blueprint2CAD benchmarks matching engineering drawings to shaded CAD renders of the same mechanical part. It pairs clean orthographic drawings and renders across controlled views, then measures retrieval with unknown or oracle-supplied view correspondence. DINOv3 achieves 43.11% Recall@1 with unknown views and 65.14% with oracle alignment, a diagnostic rather than deployable result. The benchmark covers 2D correspondence, not 3D CAD understanding.
