Sketch projection: Project (edges, face loops, body silhouettes, vertices, other sketches' curves and points, origin, axes, planes), Intersect (body/face/edge section with the sketch plane) and Include 3D Geometry as linked reference geometry: fixed, purple, re-resolved on every recompute (follows upstream edits, keeps ids when the shape is unchanged, flagged when the reference is lost), usable in profiles, constraints and dimensions; Break Link; sketching on a face auto-projects its edges (sketch.auto_project); drawing on a model vertex or edge projects it
