Logging Google SketchUp timestamp events

I'd like any ideas you have for a problem we're looking to solve via SketchUp ( as a university research project).

• For a usability study, we want create a timestamped log all the SketchUp tool changing events into a .XML, CSV, or txt file during a modeling task given to a user.开发者_运维知识库 e.g. while drawing a Cylinder, all events like- 1. selecting a circle, 2. selecting Push/Pull etc. need to be logged to a text based file.

Please pingback any neat ideas you have for doing such a plugin.

Thanks a tonne!

You would need to add an Observer Class to your project, then utilize Time.now and Ruby's built-in File IO to create and/or write to your text/log file.
