正交格条的孔壁深度

提示词

用相交直格条形成通透的正交网格，各条保留可见边面与孔内深度；格面转向时孔格随所属面改变投影，不把透空格栅画成实板上的格纹或上下交织的软网。

Form an open orthogonal grid from intersecting straight bars, retaining visible bar faces and depth within the openings. Let the openings project with each surface as it turns, rather than replacing the grating with a grid printed on a solid sheet or a soft over-under weave.
