What is the best way to change Liners and height of ductwork

[Anonymous]

Hello,

I accidentally Lined abunch of spiral ductwork.  I was wondering if there was a real easy way to turn the liner off on those ducts only.  or do I have to do it one by one? 

2nd question.

If i wanted to change the height of my ductwork how can I do so?

Thanks,

Tim

I think the quickest way would be to use the search filter to pull out all the round duct only.  Then, turn the insulation off on one and use the match properties on the CADmep toolbar with the insulation checked and select all the round duct.

Changing the elevation would just be a move in the z direction.
