@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?
