Hi All, I have created a baseline model and proposed model in open studio. As usual, I have had to change geometry in the tool and am trying to match get the changes done in the baseline model too. Since, I have used the same parent file- same space names, thermal zone names, i hoped that copying the changes would be easy enough. I tried using import envelope and idf measure, but the zone equipment seems to have lost its association and crashes when the thermal zone or plant loop tabs are selected. Is there an alternate merge solution to this?
