When you use an oriented bounding box and create the xform detail attribute, how do you apply that info to another object to match its rotation? I assume this is basic matrix transforms, but I'm still getting up to speed on those guys.

You can use attribute copy to copy the detail xform attribute over to a different object then use the node "Transform By Attribute" to apply the transform

That did it, thanks! (Turning off the Match P and copy local variable required a bit of clicking to figure out, but with your help I triumphed.)

Turning off the Match P and copy local variable required

shouldn't be required, just type xform instead of Cd into the Attribtue name

(since Match P doesn't matter if you are not copying P
and Coly Local Variable doesn't matter since even if you had some and they were copied it wouldn't affect what you are doing )
