+PCB tools extension provide three type of translation method that affects geometric finish. These method are specified a value for ```draw_mode``` attribute, as ```DM_LINE```, ```DM_MOUSE_BITES```, or ```DM_FILL```.<br>
```DM_LINE``` and ```DM_MOUSE_BITES``` are used to translate to both of RX-274x and Excellon, however ```DM_FILL``` is used to translate to only RX-274x.

- **draw_mode = DM_LINE**<br>
- All edge expressed as DXF line object, circle object, arc object and plyline objects are translated to line and arc applied a circular aperture in case of RX-274x. That circular aperture r radius is specified by ```width``` attribute. Default value of width is 0.<br>
- In case of Excellon, DXF objects are translated to routing path command sequence.

One is to arrange logo design on silk layer. This is superior to other method generating raster image data since image data express as vector data.<br>
The other one is generating gerber data represented cropped area of panelized PCB.
