## How to use?

The above macros can easily be plugged on any FreeCAD installation

• Copy the macro python code from the corresponding macro page
• In FreeCAD, Macro->Macros->Create new, and give it a name
• Paste the python code you copied
• Hit the Save button, and restart FreeCAD
• Open the Macro manager, select your new macro and click "execute"
• Tutorial How to install macros

• In FreeCAD, go to Tools -> Customize
• In the Macros tab, add a new macro, and, if you like, define an icon and a keyboard shortcut
• In the Toolbars tab, create a new toolbar, and add your macro, taking it from the "Macros" category.
• Tutorial Customize Toolbars

## Adding new macros to this repository

• Create a new page, beginning its name with "Macro", for example "Macro_My_Excellent_Macro", this can be done simply by editing this page, and adding a new link to your macro, like this:
• example :
`* {{MacroLink|Text-x-python|Macro My Excellent Macro|Macro My Excellent Macro title}} : My excellent macro description. `
• Text-x-python : icon by default (replace with your name icon with the exact same name as your macro page if there is. The format always .png only)
• Macro My Excellent Macro : macro name
• Macro My Excellent Macro title : macro name or title

A new page (red link) will be created.

• In that page, paste the following text:

(With the default icon)

```{{Macro|Icon=Text-x-python|Name=Macro_My_Excellent_Macro|Description=What my excellent macro does|Author=your username|Version=1.0}}
```

(With the icon custom)

```{{Macro|Icon=Macro_My_Excellent_Macro|Name=Macro_My_Excellent_Macro|Description=What my excellent macro does|Author=your username|Version=1.0}}
```

(Another language with the default icon (example "/fr" "/de" "/it"....))

```{{Macro/fr|Icon=Text-x-python|Name=Macro_My_Excellent_Macro|Name/fr=Macro_My_Excellent_Macro|Description=
```

(Another language with the icon custom (example "/fr" "/de" "/it"....))

```{{Macro/fr|Icon=Macro_My_Excellent_Macro|Name=Macro_My_Excellent_Macro|Name/fr=Macro_My_Excellent_Macro|Description=
```
• You can also Upload a custom format icon.png
Note that the name of the icon must have the same name as the name of the macro.
• example: " Macro_My_Excellent_Macro " without extension (the extension is given by the system), and, replace " Icon=Text-x-python " by " Icon=Macro_My_Excellent_Macro "
• Text-x-python is the default icon of the page dedicated to the Macro.
• Paste your macro, and use the Code template to avoid adding spaces into your script. This will display the macro in a monospace font inside a light grey box like the example above.
• If you like, upload a .png icon with the exact same name as your macro page (ex. Macro_My_Excellent_Macro.png)
• Add an image: an image is useful to show what the macro does. Optionally you can create an animated gif that represents the object in context. The gif image should have a maximum size of 500x500px as the wiki does not resize animated gifs; if the gif is any bigger the animation won't work.
• It is also interesting to include version information in your macro. This macro allows you to locate in time compared to the evolution of FreeCAD, do "Menu > Help > About FreeCAD and click to Copy to clipboard" and paste it your macro

Ex:

```#OS: Windows Vista
#Platform: 32-bit
#Version: 0.14.3389
#Python version: 2.6.2
#Qt version: 4.5.2
#Coin version: 3.1.0
#SoQt version: 1.4.1
#OCC version: 6.5.1 ```

Ex:

```__Title__="Title_Of_macro"
__Author__ = "User_Name"
__Version__ = "00.11"
__Date__    = "25/07/2015"

__Comment__ = "This is the comment of the macro"
