I was working in my sketchup model, I saved and closed my model, and came back to it about thirty minutes later. Everything is gone, down to layer zero, like I hit select all (including my dozens of layers) and deleted it, then saved and exited the model. I have no idea what happened. I don’t have a backup for my last 15-20 hours of work or so. I cannot recover anything from the skp file, it is totally blank.
However, the skb file is still there, and the picture preview shows my latest save of the model. Is there anything I can do to use that to save this model? Currently my computer tells me I am unable to open this file. I’m using sketchup pro 2016 on a PC running windows 10 OS.
