open the family building (modification)
a) difficult
modifies the modeling, possibly, and if possible, uses angular parameters. attention to remove and/or change existing constraints
b) easy
"copy" the shutters in the desired position, with the same parameters (and the necessary adjustments) of the existing ones, add to the fronts the display parament (si/no) that you will use in the project depending on the need
p.s. the operation requires good knowledge to the use/creation of families
p.p.s. the opening of doors does not mean automatically having more internal light in the environment for rendering
