Where surfaces meet, light should glide without a visible crease. The 1.8a engine enforces G3 continuity by default, meaning the rate of change of curvature is matched across seams. This is critical for automotive and aerospace design, where reflections reveal every imperfection.
What distinguishes 1.8a from its predecessors is not raw speed, but intelligent error correction. Three features stand out: curviloft 1.8a
