image description Every time I use the copy command in my modeling, after closing the model and opening it again for the next time, this NilClass error appears. In this situation some of my objects copy unwanted and broke my model, or sometimes it disables the object info window.

@Roziiida copy and paste operations are mostly save but can cause trouble with the SketchUp plug-in. Undo is much more dangerous to use and should be avoided. In order to fix your NilClass error you may have to manually edit the IDF file to remove bad objects. Can you post more detail about your error so we can try to help you figure out which objects to look at?

Thanks for the update, that doesn't point to anything in particular. I would suggest either trying to run your file in E+ using EP-Launch (that may generate some errors/warnings to show you what objects are invalid). Alternatively, you could try installing the new OpenStudio 1.6.0 and try importing your IDF into the new SketchUp plug-in (this might also generate some helpful errors or warnings).
