旋梯周边的错层平台

提示词

Use the supplied platform and central spiral-stair geometry and connection points to show separate horizontal platforms extending in the specified directions at different levels, each meeting its corresponding stair segment. Retain the gaps between platforms rather than stretching them into a continuous helical ramp.
