if i understand right - - -
it doesnt matter what AC u have . . .
create section trough that wall (pic1,pic2)
when u opet section of that wall click right mouse button on it and from menu
choose capture of profile section
adjust size of your cores (pic2) and select
applay to selection from profile menager and
dont store profile...
If u store every pofile u will have too many of them.
So u dont neeed to store every, just starting one.
With this metod u will have your original profile stored in your project and variations will be in your project.
you can
create gsm object or buy (siding gsm) and insert it in your project and resize all the time
U r going to deep in to BIM man....u will lose your time
U can use wall addon
