Hi all, I tried to make an example with Google SketchUp and I followed the tutorial up to page 15 but after I save the project, close the program and try to reopen it I get this error message: Sorry...the plugin has encountered an error. This error may cause unpredictable behavior in the plugin--continue this session with caution! It would probably be a good idea to exit SketchUp and start again. For help, please contact the TRNSYS newsgroup by https://www-old.cae.wisc.edu/mailman/listinfo/trnsys-users . When reporting a bug, please include the error message and backtrace below (scroll down): ERROR: NoMethodError undefined method `input_object' for nil:NilClass BACKTRACE: C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/Zone.rb:268:in `cleanup_entity' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/Zone.rb:181:in `each' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/Zone.rb:181:in `cleanup_entity' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/Zone.rb:179:in `each' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/Zone.rb:179:in `cleanup_entity' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/ModelInterface.rb:221:in `check_model' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/Bag.rb:87:in `each' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/Bag.rb:87:in `each' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/ModelInterface.rb:221:in `check_model' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/ModelInterface.rb:212:in `update_model' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/interfaces/ModelInterface.rb:118:in `draw_model' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/ModelManager.rb:183:in `open_input_file' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/ModelManager.rb:66:in `attach_input_file' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/ModelManager.rb:58:in `start' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/PluginManager.rb:138:in `new_model' C:/Programmi/Google/Google SketchUp 8/Plugins/Trnsys3d/lib/observers/AppObserver.rb:41:in `onOpenModel' Why this happens? I also tried to save the project in the directory C: \ Program Files \ Google \ Google SketchUp 8 \ Plugins \ Trnsys3d \ examples, but I always get the same error message. Can somebody help me? Thanks in advance. Best regards Davide |
