Parent Constraint Issue when removing constraint

[viru.gupta8]

Hello, i am trying to remove parent constraint using parentConstraint command.

but constraint created by skipping any Tran or Rot attrs cmds.parentConstraint(obj1, obj2, rm=True) won't work why ??

am i doing something wrong ??

here is sample code and error:

# Creating two objects
box1 = cmds.polyCube(n="box_01")[0]
box2 = cmds.polyCube(n="box_02")[0]

# Creating parent Constraint only for Translation
cmds.parentConstraint(box1, box2, mo=True, sr=["x","y","z"])

# checking if "box_02" have parent constrint
consObj =  cmds.parentConstraint(box1, q=True, tl=True)

# removing constraint
cmds.parentConstraint(consObj[0], box2, rm=True)

#Error: RuntimeError: file <maya console> line 1: Cannot edit object with no constraint.

Hi!

Change  box1 to box2:

consObj =  cmds.parentConstraint(box1, q=True, tl=True)

to

consObj =  cmds.parentConstraint(box2, q=True, tl=True)

and add e=True:

cmds.parentConstraint(consObj[0], box2 , rm=True)

to

cmds.parentConstraint(consObj[0], box2 , e=True , rm=True)

Hey Sorry about that (i have put wrong variable in my Example)

but my code was same as you corrected me.

 so here is my code again:

# Creating two objects
box1 = cmds.polyCube(n="box_01")[0]
box2 = cmds.polyCube(n="box_02")[0]

# Creating parent Constraint only for Translation
cmds.parentConstraint(box1, box2, mo=True, sr=["x","y","z"])

# checking if "box_02" have parent constrint
consObj =  cmds.parentConstraint(box2, q=True, tl=True)

# removing constraint
cmds.parentConstraint(consObj[0], box2, rm=True)

#Error: RuntimeError: file <maya console> line 1: Cannot edit object with no constraint. 

still it will give me same error

Hi!

It's not the same.

Check my correction for the last line.

Ohhh really if constraint done with all attrs then no need to pass edit flag.
Anyway thanks 🙂
