This page contains macros to add functionality to your freecad installation

Object creation

 * Macro SuperWire: Forces the creation of a Wire from lines and arcs that don't necessarily touch each other. Use this if normal wire operation fails
 * Macro HealArcs: Sometimes arcs are transformed into BSplines, for example when scale operations have been applied to them. This macro recreates valid arcs from them. Useful before exporting to dxf
 * Macro FaceToSketch: Converts the selected Face to a single Sketch without constraints.
 * Macro EdgesToArc: Converts the selected Edges to a circular Arc if possible. Useful for restoring discretized arcs.
 * Macro CloneConvert: Creates a clone of the object and the converted in the chosen position and size (inch, mm, m, µm...). The base object is recognized in mm (FreeCAd base)
 * Macro Creating faces from a DXF file: This macro create face from a DXF file, the "Layer" are recognized separate and trained in groups.

3D View operations

 * Macro Rotate View This macro rotates the current view by 90° to the left. Only works if you are in Top view.
 * Macro View Rotation Provides a GUI to permit rotation of view by precise amounts in all three directions.
 * Macro Texture Objects This macro allows you to temporarily put a texture image on the selected objects.
 * Macro Mouse Cross This small macro turns the arrow of the mouse in a precision cross
 * Macro Align ViewToFace This macro aligns the current view to a selected face

Wizards

 * Macro Automatic Drawing: allows the user to get the view of his object in a drawing with 4 different position(front,top,iso,right). Needs some modification to be perfectly effective
 * Macro Corner Shapes Wizard: pops up a dialog asking for the dimensions of your corner piece, then creates the object in the document and creates a page view with top, front and lateral views of the piece
 * Macro CartoucheFC: This GUI macro to fill simply all fields of the cartridge of the plan implementation worksheet FreeCAD, the format of the date and the symbol of the projection mode adapt to the EU region or US selected.
 * Macro CartoucheFC Full: (Full field edition for this Templates) This GUI macro to fill simply all fields of the cartridge model 1 of the plan implementation worksheet FreeCAD, the format of the date and the symbol of the projection mode adapt to the EU region or US selected.
 * Macro CartoucheFC 2: (Full field edition for this Templates) This GUI macro to fill simply all fields of the cartridge model 2 of the plan implementation worksheet FreeCAD.
 * Macro UnrollRuledSurface: allows to unroll ruled surfaces and to draw them on a page.
 * Macro UnfoldBox: allows to unfold the surfaces of a box of any shape and to draw them on a page.
 * Macro Geneva Wheel GUI: A GUI front end that allows the user to create a Geneva wheel mechanism from scratch.
 * [[Image:Part_Prism_Apothem.svg|16px]] Macro Apothem Based Prism GUI A GUI dialog that creates an Apothem, (inradius) Based Prism from user input.

Utility

 * Macro MessageBox: shows how to give information to the user through the GUI.
 * [[Image:FCInfo.png|16px]] Macro FCInfo : Gives a series of information about the selected shape and can display a conversion of length, inclination (degrees, radian, grade) shape, surface, volume and the weight of the form in the density selected in various international and Anglo-Saxon units
 * [[Image:FCInfo.png|16px]] Macro FCInfo Alternate Linux : same as above, but for Linux
 * Macro 3D Printer Slicer: Exports current design to slicer software or CAM software.

 * Macro CenterFace : This macro red trace (editable) the center face (mass) with 1 point and print the coordinates
 * Macro ObjectInfo: User-friendly "Info" module created by a FreeCAD user
 * MacroMenu: Add the macros found in the macros folder to the Macros menu of FreeCAD
 * [[Image:Force_Recompute.png|16px]] Macro ForceRecompute : Forces manual recompute of model
 * Macro Shake Sketch: Shake a sketch in order to discover its unconstrained parts.
 * Macro Replace_Part_in_Assembly: Replaces a part (simple copy) in an "Assembly" with another Part (simple copy).

Animation

 * Macro Crank Simul : Rotation rod and piston
 * Macro Spring : simulation of one spring
 * Macro Hinge : Open and close hinge
 * Macro Assembly : Assembly animate

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"
 * Section animated : create animated gif that represents the object in context. Create animated gif max 500 x 500 px the site does not accept resizing animated gif otherwise it stays dead.

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.

Adding new macros to this repository
A new page (red link) will be created.
 * 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: "Macro My Excellent Macro: My excellent macro".
 * 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   preformated text wiki tags 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)
 * 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:


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