## 3. Comandos de la barra de menús

### 3.1. Menú archivo

- Export to PCB Editor is a limited capability to export Gerber files into a KiCad PCB. The final result depends on what features of the RS-274X format are used in the original Gerber files: rasterized items cannot be converted (typically negative objects), flashed items are converted to vias, lines are converted to track segments (or graphic lines for non-copper layers).

### 3.2. Tools menu

- List DCodes shows the D Code information for all layers.

- Show Source displays the Gerber file contents of the active layer in a text editor.

- Measure Tool allows measuring the distance between two points.

- Clear Current Layer erases the contents of the active layer.

## 4. Printing

To print layers, use the icon or the File → Print menu.

Caution | Be sure items are inside the printable area. Use to select a suitable page format. Note that many photoplotters support a large plottable area, much bigger than the page sizes used by most printers. Moving the entire layer set may be required.
