アーティストのためのMaya Python入門 第８回「constraint系コマンドを使って、ノード同士の位置合わせ！」

from maya import cmds

# point snap
source, dist = cmds.ls(selection=True)
constraint_node = cmds.pointConstraint(source, dist)
cmds.delete(constraint_node)

# orient snap
source, dist = cmds.ls(selection=True)
constraint_node = cmds.orientConstraint(source, dist)
cmds.delete(constraint_node)

# parent snap
source, dist = cmds.ls(selection=True)
constraint_node = cmds.parentConstraint(source, dist)
cmds.delete(constraint_node)
