Draw 如何在VMD上绘制多个pbc盒？

现在，我有： pbc盒-颜色黑色-宽度1 pbc集{4.541 4.541 6.463 69.5 69.5 90}

如何制作另一个？

允许这样做。例如：

# draw small box
pbc set {10 10 10}
set box0 [pbc box_draw -width 1 -color black]

# draw large box
pbc set {15 15 15}
set box1 [pbc box_draw -width 1 -color black]

如果以后需要删除框，可以按如下方式执行：

# delete all objects associated with the box
foreach i $box0 {
    graphics top delete $i
}
