## DXF file translation
pcb-tools-extension hsa a function to load a DXF file and handle that as same as RX-274x gerber file or Excellon NC file.<br>
In this version, Only line, circle, arc, and polyline objects are recognized and are translated to gerber file or NC file.
### PCB Outline
You can also load a dxf file and handle that as same as RX-274x gerber file or Excellon NC file.<br>
This function is useful to generate outline data of pnanelized PCB boad.
### Two way to tranlate DXF file
Both composition objects, ```GerberComposition``` for RX-274x and ```DrillionComposition``` for Excellon, can accept an object created as result of DXF file loaded. When composition object dump text stream, DXF data tranclate to appropriate format data.<br>
The object which represent DXF file, can also output translated data directly by ```save``` method. In this case output format is specified by ```filetype``` argument. If ```filetype``` argument is ommited, DXF data is translated to RX-274x gerber data.
```python
import gerberex
dxf = gerberex.read('sample.dxf')
dxf = gerberex.read('outline.dxf')
ctx1 = gerberex.GerberComposition()
ctx1.merge(dxf)
ctx2 = gerberex.DrillComposition()
ctx2.merge(dxf)
```
Circle object, Arc object, Line object and Polyline object are supported. Other kind of objects in DXF file are ignored when translating to gerber data.
# translate to RX-274x using composition object
ctx = gerberex.GerberComposition()
ctx.merge(dxf)
ctx.dump('sample.gml')
You can specify line width (default 0). PCB tools extension will translate DXF primitive shape to RX-274x line or arc sequense using circle aperture with diamater as same as specified line width. <br>
# translate to Excellon using composition object
ctx = gerberex.DrillComposition()
ctx.merge(dxf)
ctx.dump('sample.txt')
```python
import gerberex
# translate to RX-274x directly
dxf.save('sample2.gml')
dxf = gerberex.read('outline.dxf')
dxf.to_inch()
dxf.width = 0.004
dxf.write('outline.gml')
```
If ```FT_EXCELLON``` is specified for ```filetype``` argument of ```write()```, Excellon NC data is generated. In this case, Excellon file consists of routing commands using a specified width drill.
```python
import gerberex
dxf = gerberex.read('outline.dxf')
dxf.to_metric()
dxf.width = 0.3
dxf.write('outline.txt', filetype=dxf.FT_EXCELLON)
```
You can also translate DXF closed shape such as circle to RX-274x polygon fill sequence.<br>
In order to fill closed shape, ```DM_FILL``` has to be set to ```draw_mode``` property. In this mode, All object except closed shapes listed below are ignored.
- circle
- closed polyline
- closed path which consists of lines and arcs
NOTE: ```DM_FILL``` can be used only to generate RX-274x data, it cannot be used to generate Excellon data.
```python
import gerberex
dxf = gerberex.read('outline.dxf')
dxf.draw_mode = dxf.DM_FILL
dxf.write('outline.gml')
# translate to Excellon directly
dxf.save('sample2.txt', filetype=dxf.FT_EXCELLON)
```
### Generating Rectangle
If you want to arrange simple rectangle for PCB outline, ```gerberex.rectangle()``` is better solution. This generate a object representing a rectangle compatible with DXF file object.<br>
```python
@ -134,30 +106,83 @@ outline = gerberex.rectangle(width=100, height=100, units='metric')
outline.write('outline.gml')
```
### Mouse bites
### Drawing Mode
PCB tools extension provide three type of translation method that affects geometric finish. These method are specified a value for ```draw_mode``` attribute, ```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.
<img alt="mouse bites" src="https://raw.githubusercontent.com/wiki/opiopan/pcb-tools-extension/images/mousebites.png" width=200 align="right">
![Drawing Mode](https://raw.githubusercontent.com/wiki/opiopan/pcb-tools-extension/images/draw_mode.jpg)
- **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.
This function is useful to generate outline data of pnanelized PCB boad.
If ```DM_MOUSE_BITES``` is specified for ```draw_mode```, filled circles are arranged at equal intervals along a paths consisted of DXF line, arc, circle, and plyline objects. <br>
DXF file object in this state can be merged to excellon file also. That means you can arrange mouse bites easily.
```python
import gerberex
```python
import gerberex
dxf = gerberex.read('outline.dxf')
dxf.to_inch()
dxf.width = 0.004
dxf.write('outline.gml')
```
ctx = gerberex.DrillComposition()
drill = gerberex.read('drill.txt')
ctx.merge(drill)
- **draw_mode = DM_MOUSE_BITES**<br>
<img alt="mouse bites" src="https://raw.githubusercontent.com/wiki/opiopan/pcb-tools-extension/images/mousebites.png" width=200 align="right">
If DM_MOUSE_BITES is specified for draw_mode, filled circles are arranged at equal intervals along a paths consisted of DXF line, arc, circle, and plyline objects.
DXF file object in this state can be merged to excellon file also. That means you can arrange mouse bites easily.
dxf = gerberex.read('mousebites.dxf')
dxf.draw_mode = dxf.DM_MOUSE_BITES
dxf.to_metric()
dxf.width = 0.5
dxf.pitch = 1
ctx.merge(dxf)
```python
import gerberex
ctx = gerberex.DrillComposition()
drill = gerberex.read('drill.txt')
ctx.merge(drill)
dxf = gerberex.read('mousebites.dxf')
dxf.draw_mode = dxf.DM_MOUSE_BITES
dxf.to_metric()
dxf.width = 0.5
dxf.pitch = 1
ctx.merge(dxf)
ctx.dump('merged_drill.txt')
```
- **draw_mode = DM_FILL**<br>
You can translate DXF closed shape such as circle to RX-274x polygon fill sequence.<br>
In order to fill closed shape, ```DM_FILL``` has to be set to ```draw_mode``` property. In this mode, All object except closed shapes listed below are ignored.
- circle
- closed polyline
- closed path which consists of lines and arcs
If a closed shape is completly included in other closed shape, The inner shape will be draw with reversed polality of container shape as above example image.<br>
I assume there are two typical usecase for this mode.<br>
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.
By merging rectangle and PCB outline data, generate a file represented cropped area as below, and this kind of data is useful to make PCB image look good a little bit.<br>
[This script](https://github.com/opiopan/pcb-tools-extension/blob/master/examples/genimage.py) which generate example image shown below, also uses this technic.
```python
import gerberex
ctx = gerberex.GerberComposition()
rectangle = gerberex.rectangle(width=100, height=100, units='metric')
rectangle.draw_mode = rectangle.DM_FILL
ctx.merge(rectangle)
outline = gerberex.read('outline.dxf')
outline.draw_mode = outline.DM_FILL
outline.negate_polarity()
ctx.merge(outline)
ctx.dump('cropped_area.gml')
```
NOTE: ```DM_FILL``` can be used only to generate RX-274x data, it cannot be used to generate Excellon data.
ctx.dump('merged_drill.txt')
```
## Panelizing Example
