I am using Sketchup 2017 and OpenStudio 2.1.0 and when I intersect either in selection or entire model open studio adds the new lines but all of the new surfaces have the original surface ###. Making it impossible to match and when you close and reopen the model, all of the duplicate surfaces are not rendered leaving the model pretty much useless. I have replicated the issue on three different machines in the office with new and previous models. I am wondering if this is an issue with Sketchup 2017 or the OpenStudio 2.1.0? Desperate for help!!!
