# Advanced Features

In this chapter we present features used to extend the cabilities of DR. GEOin various ways.

The first is macro-construction; it allows the extraction of a construction logic in a record. Then, this record can be repeated or saved as a file.

The DR. GEOGuile Script features are the other means for extending DR. GEO. These scripts are really figure items like the other geometric items. They receive as input, user selected figure item references and they return values, plugged into figures.

DR. GEOGuile Scripts can be useful for their returned values or their side effects; which really depends on what the user wants to achieve.

The last feature is user-interface customisability. The idea is to give the teacher the cability to prepare geometric figure files with tools taken from the Dr. Genius toolbar and contextual menu. This capability may help in achieving a desired "pedagogical effect"

- Macro-Construction
- DR. GEOGuile Script
- User interface customisation
