==== 基本コード ====

<code python>
rs.AddBox(points)
</code>

  *API [[https://developer.rhino3d.com/api/RhinoScriptSyntax/#surface-AddBox|AddBox]]

AddBox関数には、8つの頂点座標を指定する必要があり、その並び順にもルールがある。\\
この関数をそのまま使用するのはとても不便なので、対角線上にある2点を指定するだけで直方体が生成される、次の関数を使うとよい。

<code python>
def box2pt(p1, p2):
    pt0 = p1
    pt1 = rs.coerce3dpoint([p2[0], p1[1], p1[2]])
    pt2 = rs.coerce3dpoint([p2[0], p2[1], p1[2]])
    pt3 = rs.coerce3dpoint([p1[0], p2[1], p1[2]])
    pt4 = rs.coerce3dpoint([p1[0], p1[1], p2[2]])
    pt5 = rs.coerce3dpoint([p2[0], p1[1], p2[2]])
    pt6 = p2
    pt7 = rs.coerce3dpoint([p1[0], p2[1], p2[2]])

    return rs.AddBox([pt0, pt1, pt2, pt3, pt4, pt5, pt6, pt7])
</code>


==== サンプルコード(1) ====
<code python>
import rhinoscriptsyntax as rs

a = []

def box2pt(p1, p2):
    pt0 = p1
    pt1 = rs.coerce3dpoint([p2[0], p1[1], p1[2]])
    pt2 = rs.coerce3dpoint([p2[0], p2[1], p1[2]])
    pt3 = rs.coerce3dpoint([p1[0], p2[1], p1[2]])
    pt4 = rs.coerce3dpoint([p1[0], p1[1], p2[2]])
    pt5 = rs.coerce3dpoint([p2[0], p1[1], p2[2]])
    pt6 = p2
    pt7 = rs.coerce3dpoint([p1[0], p2[1], p2[2]])

    return rs.AddBox([pt0, pt1, pt2, pt3, pt4, pt5, pt6, pt7])
    
a.append(box2pt([0,0,0], [100,200,50]))
