i’m using SketchUp Make 2015 (currently Pro for a month) in order to analyse my model with desighPH plugin. Initial model is created in Archicad, therefore there are way to many surfaces for my purpouse. As i start deleting what i don’t need at some point the whole model is not visible anymore. Nothing is hidden, all the Layers on… i wonder if i’ve managed to delete the whole thing but my groups are there (if it is of relevance). Anyway Undo does not help. Please tell me what i\m doing wrong and how cani get my model back.
