溫室鋼木節點的CAD風細節

A technical drawing without readable text. The connection nodes between steel beams and wooden beams in a greenhouse are represented by white thin lines, cut-out shadows and two bolt shapes. The structure is accurate on a dark blue background; only short scale lines are used and no forged numbers are written.

無可讀文字的技術製圖畫面，一處溫室鋼樑與木樑的連線節點以白色細線、剖切陰影和兩種螺栓形狀表示，深藍底上結構準確；只用短刻度線，不寫偽造數字。
