Demolitions and new parts - schedules

[alemanda]

I'm working on a renovation project.
I have existing walls with existing Windows and doors.
Some of these Windows and doors will be canceled and some new Windows and doors will be added.
I need to have the quantities of volumes of wall to be demolished and the volumes to be built.
Is it possible to have it without making subtractions?
I mean, until now the only way I found was having the quantity of walls after demolition and existing and by subtraction I was able to get the volumes to be demolished.
Then I had the quantities in the design stage and by subtraction I got the quantities to be built ...
Is there a quicker way to get quantities of parts to bemoans he'd and parts to be built?
Thanks

Create 4 Openings: 2 for the yellow ones, 1 for the orange part, one for the remainder?

Mmmmm...
I thought it would have been easier ...
So in these cases of new and to be demolished openings mixing each other this is the workaround ...
Also, I have to add an other opening to not be considered in volume quantity take off: the new big one (given by the sum of the two yellow ones and the central part of the small existing one). This will be the new design one ...
Correct?
