Changing Pitch

[Fredo649]

Hi folks , Just a question before I mess up . I've done a plan with an 8/12 pitch throughout hip and gable roof styles . My question is … is it possible to change the pitch on the whole roof from 8/12 to 9/12 without going to each section and changing manually , can it be done through preferences . Just asking before I attempt .

Thanks.

Select all the roof planes, open them and change.
