透明板后的线条层次

提示词

在节点线图中，仅透过指定透明板显示资料确认的后方构件线，保留板边和已知厚度轮廓；前景不透明构件仍按原几何遮挡，不把整个节点变成透视内部的线架。

In the node drawing, show documented rear-component linework only through the selected transparent panels, retaining panel edges and known thickness outlines. Preserve occlusion by opaque foreground parts rather than turning the entire node into a see-through wireframe.
