## General Tools

### File Operations

The file operations are rather standard and similar to corresponding operations in other programs. Constructions are stored in a special file format. The construction files have the extension ".cdy".
New
This action clears the entire construction. Everything is reset to the original state.
Load
Loads a construction.
Save
Prompts for a filename if needed and saves the construction.
Save As
Prompts for a new filename and saves the construction.

### Export Tools

Print All Views
Prints all currently open views. This operation makes use of the Java printing routines. The output is inferior to the output produced using the "Print PS" command of a view, due to the limits of the Java printing interface. If you have the facilities to print and preview PostScript files (we recommend installing Ghostscript and GSView or gv), it is much better to use the PostScript printout routines.
Export to HTML
This operation automatically generates an interactive HTML page.
Create an Exercise
With this operation you can generate student exercises, which can be used inside a standard web browser. You can read more about this in the chapter on creating interactive web pages? and exercises.

### Undo/Redo/Delete

Undo
This operation undoes the last performed action. The following actions are undoable:

- Construction steps
- Movements
- Appearance changes
- Zooming, translating, and rotating views
- Deletion of elements

You can undo as many consecutive operations as you want.
Redo
Redoes the last undo operation. You can redo as many consecutive undo operations as you want.
Delete
Deletes all selected elements and all elements that depend on them. If you delete elements by accident, just use "Undo" to restore them.

### Selection Tools

Selects all points.
