トランスフォームの順序は、プロパティを設定する順序に影響しません。
順序を設定するためのプロパティは
'transform_order'、
'rotate_order'
になります。
デフォルトでは
ORDER_SRTであり、変換はスケール、回転、移動の順
ORDER_XYZです。回転はx,y,z軸回転の順
に行われます
SetProperty1 obj1 transform_order ORDER_RST
または
si.SetProperty1('obj1', 'transform_order', 'ORDER_RST')
として変更します。

らせん階段をつくるのに
以下のようにスケール、移動、回転の順に変更しています。



si.SetProperty1('cube'+str(j), 'transform_order', 'ORDER_STR')

si.SetProperty3('cube'+str(j), 'translate', x0,y0,z0)

si.SetProperty3('cube'+str(j), 'rotate', 0,rot,0)

si.SetProperty3('cube'+str(j), 'scale', 1,0.5,3.5)
