Domain skill - create basic primitives, bounded native Lathe geometry, splines and curve models, and lofted surfaces on the 3ds Max main thread. Use when adding boxes, spheres, cylinders, planes, a rotational form from a typed profile, a spline drawn from world-space points, a named parametric curve model, or a loft from matching cross-sections. Not for mesh editing, boolean operations, import/export, or material assignment.
