Another cool Maya bit.
connectAttr -f objectA.outMesh objectB.inMesh
This command will make objectB a copy of objectA as it appears with all transforms at Zero. It basically takes the output geometry of objectA and pumps it into objectB
ObjectB will get all the deformations of ObejctA. However, the translations, rotations, and scales of the two objects remains seperate.
It’s up to you to figure out what to do with this bit of knowledge.
