setAttr heightBaseline?

[klawchi]

I am trying to change the heightBaseline of a selcted object but can't get any solutions 😞

import maya.cmds as cmds
selected = cmds.ls(sl=True)[0]
cmds.setAttr(selected.heightBaseline, -1)

I tried to query the baseline with:

baseline = cmds.getAttr('{0}.heightBaseline'.format(selected))

But no luck

Any help will be appreciated

you have to wrap literal strings in "quotes". If you want to "join" them to object names, you have to concatenate them. There are different (and better) ways to do this in Python, but the simplest way is like so:

import maya.cmds as cmds
selected = cmds.ls(sl=True)[0]
cmds.setAttr(selected+".heightBaseline", -1)

However, this is not your issue. The issue is that .heightBaseLine is an attribute of the history of an object, and what you have selected is likely the transform. You either have to select the history node, and the code snippet will work, or you have to find the history node from the selected transform/mesh. 

Something like:

selected = cmds.ls(sl=True)[0]
hist = cmds.listHistory(selected, pruneDagObjects=True)[0]
cmds.setAttr(hist+'.heightBaseLine', -1)

(but this becomes more complex if you have objects with more than one history state).

Yes, this is fixed the issue.

Thank you for explaining it in details.
