How to use
You can add macros to an existing FreeCAD installation. See How to install macros for a full description, Customize toolbars for adding the macro to a toolbar for easy access.

Automatic installation
Starting with FreeCAD 0.17, use the Addon Manager to install any macro from this list.

Manual installation
If the Addon Manager is not used, the macro can be installed manually.
 * Copy the Python code from the corresponding macro page.
 * Open the macros menu, press , and give it a name.
 * Paste the Python code that you copied.
 * Press the button, and restart FreeCAD.
 * Open again the macros menu, select your new macro, and press.

Add a macro to a custom toolbar
You can add a button that launches a particular macro to a custom toolbar.
 * Go to.
 * In the tab, add a new macro and optionally define an icon and a keyboard shortcut.
 * In the tab, create a new toolbar, and add your macro, taking it from the "Macros" category.



New macro page
Create a new page for the macro, starting with the word, for example,. The spaces are automatically converted to underscores.

In the new page, for example, Macro Excellent Modification, you should use Template:Macro at the top, with a minimum of information:

You can add a custom icon if it doesn't have the same name as the macro; you can also add other information.

When translating the page, use a localized template. You need to specify the name with the two letter language code, and you need to add the icon specifically.


 * Use Special:Upload to upload the custom icon in SVG or PNG formats. It should have the same name as the macro.
 * Otherwise it will default to, [[Image:Text-x-python.png|32px]].

Code
Use Template:Code to place the code of the macro. It will use a monospace font and will preserve the white spaces that are essential for Python.


 * Document the way of using your macro in the same way the Gui Commands are documented.
 * Add one or more images to clarify what the macro does.
 * If the macro is complex, consider adding an animated GIF that shows its capabilities. The GIF image should have a maximum size of 500 x 500 pixels; if the GIF is bigger, the animation may not work. Do not resize the GIF as the wiki will not play resized GIFs.
 * Mention any tips and limitations of your macro, and the version of FreeCAD used to create it. This information can be gathered from.


 * When this information is pasted, it looks like this


 * Add header information to your code.

This information can be used by the addons_installer.FCMacro macro, or by the Plugin Loader program, to install the macro and check for new versions. Starting with FreeCAD 0.17, you don't have to use these programs any more, as the macros can be installed directly from the Addon Manager.

Adding the new macro to the list
Use Template:MacroLink to include a line in the appropriate category in this page, or create a new category if needed.


 * The first argument is the name of the macro page in this wiki.
 * The second argument is the displayed text, which may be different from the page name.
 * What follows is a short description of the macro.


 * The optional parameter  may be given to specify the image file that will be used at the start of the line. The icons should be SVG or PNG files, and should have the same name as your macro. If this parameter is not given it will use the default icon for a Python script, [[Image:Text-x-python.png|24px]].

Adding new macro page with macro code extra wiki
If your macro is too big (+64Ko) and does not fit in the wiki page, use the   template by giving the address of the RAW page of the macro

The template must always be placed at the beginning of the page below the Description (must be the first code detected by the addonManager macro, in case there are code examples in the page, if a sample code is detected is this code that will be installed and not the code of the macro)

Example given:
