Let's say you have an IfcCovering that is an AXIS2(vertical layers), how do you do a quantity take-off to get the length--since Qto_CoveringBaseQuantities
only covers the following...

Or similarly if you have an IfcCovering that is profile/extrusion based, how do you get the length?

You could use the manual quantification method under costing and scheduling tab
bingo! Thanks @Massimo!
