how to access the volume of wall elements in Property set def

[Brian_Adams]

Do you know how to extract the volume from the wall ( in property set def.) some of its components and put it into the table 

[Francis.Scarpinato]

When yousay table, do you mean the wall schedule?  If so, you can go to Style Manager -> Drawing File -> Documentation Objects -> Schedule Table Styles -> Wall Schedule -> and click the Add Column button at the bottom.  Volume should be an option if it is in the property set definition.

If you mean the table in your first screen shot, I don't think there will be a volume in that table because it is defining the wall style.  There is no actual wall to determine a volume.

I meant- to have the possibility to see the volume of the component that corresponds to a particular index (index 1,2 ..... 4) but not of  the whole wall ,using Visual Basic ( in formula) in Prop. Set def.
