Term Project - BIM Macros

Topic: BIM Macros - "Explore Revit's macro language and develop one or more useful macros that you can use to demonstrate the capability."
In an interview for a co-op of acoustic engineering, the interviewer raised the questions that if I had any experience on macros, and that's when I realized the use of macro did not limit to MS Excel. Based on my experience of Revit, there are many process including repeated operations, and a macro would save much time from that.
