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: Opens a new and empty construction window.
• 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

• Export to HTML: This operation automatically generates an interactive HTML page.
• 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 PDF" command of a view, due to the limits of the Java printing interface. If you have the facilities to print and preview PDF files, it is much better to use this print format.

Undo/Redo/Delete

• Undo: This operation undoes the last performed action. You can undo as many consecutive operations as you want. The following actions are undoable:
  • Construction steps
  • Movements
  • Appearance changes
  • Zooming, translating, and rotating views
  • Deletion of elements
• 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

• Select All: Selects all geometric elements.
• Select Points: Selects all points.
• Select Lines: Selects all lines.
• Select Conics: Selects all conics and circles.
• Deselect: Clears the current selection.
