How to use?


The above macros can easily be plugged on any FreeCAD installation
 * Starting from FreeCAD v 0.17, a new Tools -> Addons Manager allows you to easily install any macro from this page. The instructions below must still be followed if your version of FreeCAD doesn't have the Addons Manager yet.
 * 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

Additionally, you can also add your new macro to a custom toolbar
 * 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 :


 * 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)

(With the icon custom)

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

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

Note that the name of the icon must have the same name as the name of the macro.
 * You can also Upload a custom format icon.png
 * 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 [[Image:Text-x-python.png|32px]] 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.
 * Optionally you can add some more info on how to use your macro, tips, limitations and workaround.
 * 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:

It is also advisable to create a macro in your header, this header can be used by the Plugin Loader program to install the macro and check versions. Also available addons_installer.FCMacro

Ex:


 * Add it to the above categories, create a new category if needed.
