Every module must contain, besides your main module file, an InitGui.py file, responsible for inserting the module in the main Gui. This is an example of a simple one. |

Making an importer for a new filetype in FreeCAD is easy. FreeCAD doesn't consider that you import data in an opened document, but rather that you simply can directly open the new filetype. So what you need to do is to add the new file extension to FreeCAD's list of known extensions, and write the code that will read the file and create the FreeCAD objects you want: |

Introduction
Cette page contient des exemples, des pièces, des extraits de code FreeCAD en Python, recueillis auprès d'utilisateurs expérimentés et de discussions sur les forums. Lisez les et utilisez les comme point de départ pour vos propres scripts...
Snippets
Un fichier typique InitGui.py
En plus de votre module principal, chaque module doit contenir, un fichier InitGui.py, responsable de l'insertion du module dans l'interface principale.
Ceci est un simple exemple.
Every module must contain, besides your main module file, an InitGui.py file, responsible for inserting the module in the main Gui. This is an example of a simple one.
class ScriptWorkbench (Workbench):
MenuText = "Scripts"
def Initialize(self):
import Scripts # assuming Scripts.py is your module
list = ["Script_Cmd"] # That list must contain command names, that can be defined in Scripts.py
self.appendToolbar("My Scripts",list)
Gui.addWorkbench(ScriptWorkbench())
Un fichier module typique
Ceci est l'exemple d'un fichier module principal, il contient tout ce que fait votre module. C'est le fichier Scripts.py invoqué dans l'exemple précédent. Vous avez ici toutes vos commandes personnalisées.
This is an example of a main module file, containing everything your module does. It is the Scripts.py file invoked by the previous example. You can have all your custom commands here.
import FreeCAD, FreeCADGui
class ScriptCmd:
def Activated(self):
# Here your write what your ScriptCmd does...
FreeCAD.Console.PrintMessage('Hello, World!')
def GetResources(self):
return {'Pixmap' : 'path_to_an_icon/myicon.png', 'MenuText': 'Short text', 'ToolTip': 'More detailed text'}
FreeCADGui.addCommand('Script_Cmd', ScriptCmd())
Importer un nouveau type de fichier
Importer un nouveau type de fichier dans FreeCAD est facile. FreeCAD ne prends pas en considération l'importation de n'importe quelle données dans un document ouvert, parce que, vous ne pouvez pas ouvrir directement un nouveau type de fichier.
Donc, ce que vous devez faire, c'est ajouter la nouvelle extension de fichier à la liste des extensions connues de FreeCAD, et, d'écrire le code qui va lire le fichier et créer les objets FreeCAD que vous voulez.
Making an importer for a new filetype in FreeCAD is easy. FreeCAD doesn't consider that you import data in an opened document, but rather that you simply can directly open the new filetype. So what you need to do is to add the new file extension to FreeCAD's list of known extensions, and write the code that will read the file and create the FreeCAD objects you want:
Cette ligne doit être ajoutée au fichier InitGui.py pour ajouter la nouvelle extension de fichier à la liste:
# Assumes Import_Ext.py is the file that has the code for opening and reading .ext files
FreeCAD.addImportType("Your new File Type (*.ext)","Import_Ext")
Puis, dans le fichier Import_Ext.py, faites:
def open(filename):
doc=App.newDocument()
# here you do all what is needed with filename, read, classify data, create corresponding FreeCAD objects
doc.recompute()
Pour exporter votre document avec une nouvelle extension, le fonctionnement est le même, mais vous devrez faire:
FreeCAD.addExportType("Your new File Type (*.ext)","Export_Ext")
Ajouter une ligne
Une ligne, à uniquement deux points.
A line simply has 2 points.
import Part,PartGui
doc=App.activeDocument()
# add a line element to the document and set its points
l=Part.LineSegment()
l.StartPoint=(0.0,0.0,0.0)
l.EndPoint=(1.0,1.0,1.0)
doc.addObject("Part::Feature","Line").Shape=l.toShape()
doc.recompute()
Ajouter un polygone
Un polygone est simplement un ensemble de segments connnectés (un polyline dans AutoCAD) il n'est pas obligatoirement fermé.
A polygon is simply a set of connected line segments (a polyline in AutoCAD). It doesn't need to be closed.
import Part, PartGui
doc = App.activeDocument()
n = list()
# create a 3D vector, set its coordinates and add it to the list
v = App.Vector(0,0,0)
n.append(v)
v = App.Vector(10,0,0)
n.append(v)
#... repeat for all nodes
# Create a polygon object and set its nodes
p = doc.addObject("Part::Polygon","Polygon")
p.Nodes = n
doc.recompute()
Ajout et suppression d'objet(s) dans un groupe
doc=App.activeDocument()
grp=doc.addObject("App::DocumentObjectGroup", "Group")
lin=doc.addObject("Part::Feature", "Line")
grp.addObject(lin) # adds the lin object to the group grp
grp.removeObject(lin) # removes the lin object from the group grp
PS: vous pouvez aussi ajouter un groupe dans un groupe . . .
Ajout d'une maille (Mesh)
import Mesh
doc=App.activeDocument()
# create a new empty mesh
m = Mesh.Mesh()
# build up box out of 12 facets
m.addFacet(0.0,0.0,0.0, 0.0,0.0,1.0, 0.0,1.0,1.0)
m.addFacet(0.0,0.0,0.0, 0.0,1.0,1.0, 0.0,1.0,0.0)
m.addFacet(0.0,0.0,0.0, 1.0,0.0,0.0, 1.0,0.0,1.0)
m.addFacet(0.0,0.0,0.0, 1.0,0.0,1.0, 0.0,0.0,1.0)
m.addFacet(0.0,0.0,0.0, 0.0,1.0,0.0, 1.0,1.0,0.0)
m.addFacet(0.0,0.0,0.0, 1.0,1.0,0.0, 1.0,0.0,0.0)
m.addFacet(0.0,1.0,0.0, 0.0,1.0,1.0, 1.0,1.0,1.0)
m.addFacet(0.0,1.0,0.0, 1.0,1.0,1.0, 1.0,1.0,0.0)
m.addFacet(0.0,1.0,1.0, 0.0,0.0,1.0, 1.0,0.0,1.0)
m.addFacet(0.0,1.0,1.0, 1.0,0.0,1.0, 1.0,1.0,1.0)
m.addFacet(1.0,1.0,0.0, 1.0,1.0,1.0, 1.0,0.0,1.0)
m.addFacet(1.0,1.0,0.0, 1.0,0.0,1.0, 1.0,0.0,0.0)
# scale to a edge langth of 100
m.scale(100.0)
# add the mesh to the active document
me=doc.addObject("Mesh::Feature","Cube")
me.Mesh=m
Ajout d'un arc ou d'un cercle
import Part
doc = App.activeDocument()
c = Part.Circle()
c.Radius=10.0
f = doc.addObject("Part::Feature", "Circle") # create a document with a circle feature
f.Shape = c.toShape() # Assign the circle shape to the shape property
doc.recompute()
Accéder et changer la représentation d'un objet
Chaque objet dans un document FreeCAD a un objet de représentation de vue associé qui stocke tous les paramètres qui définissent la façon dont cet objet apparaît: c'est-à-dire la couleur, la largeur de ligne, etc... Voir aussi l'extrait ci-dessous Lister les composantes d'un objet.
Each object in a FreeCAD document has an associated view representation object that stores all the parameters that define how that object appears: i.e. color, linewidth, etc... See also List the components of an object snippet below
gad = Gui.activeDocument() # access the active document containing all
# view representations of the features in the
# corresponding App document
v = gad.getObject("Cube") # access the view representation to the Mesh feature 'Cube'
v.ShapeColor # prints the color to the console
v.ShapeColor=(1.0,1.0,1.0) # sets the shape color to white

Observation des évènements de la souris dans la vue 3D via Python
Le cadre Inventor permet d'ajouter un ou plusieurs noeuds (nodes) de rappel à la scène graphique visualisée. Par défaut, FreeCAD, possède un noeud (node) de rappel installé par la visionneuse (fenêtre d'affichage des graphes), qui permet d'ajouter des fonctions statiques ou globales en C++. Des méthodes de liaisons appropriées sont fournies avec Python, pour permettre l'utilisation de cette technique à partir de codes Python.
The Inventor framework allows to add one or more callback nodes to the scenegraph of the viewer. By default in FreeCAD one callback node is installed per viewer which allows to add global or static C++ functions. In the appropriate Python binding some methods are provided to make use of this technique from within Python code.
App.newDocument()
v=Gui.activeDocument().activeView()
#This class logs any mouse button events. As the registered callback function fires twice for 'down' and
#'up' events we need a boolean flag to handle this.
class ViewObserver:
def logPosition(self, info):
down = (info["State"] == "DOWN")
pos = info["Position"]
if (down):
FreeCAD.Console.PrintMessage("Clicked on position: ("+str(pos[0])+", "+str(pos[1])+")\n")
o = ViewObserver()
c = v.addEventCallback("SoMouseButtonEvent",o.logPosition)
Maintenant, choisissez une zone dans l'écran (surface de travail) 3D et observez les messages affichés dans la fenêtre de sortie. Pour terminer l'observation il suffit de faire:
v.removeEventCallback("SoMouseButtonEvent",c)
Les types d’évènements suivants sont pris en charge:
- SoEvent -- tous types d'évènements
- SoButtonEvent -- tous les évènements, boutons, molette
- SoLocation2Event -- tous les évènements 2D (déplacements normaux de la souris)
- SoMotion3Event -- tous les évènements 3D (pour le spaceball)
- SoKeyboardEvent -- évènements des touches flèche haut et flèche bas
- SoMouseButtonEvent -- tous les évènements boutons Haut et Bas de la souris
- SoSpaceballButtonEvent -- tous les évènements Haut et Bas (pour le spaceball)
Les fonctions Python qui peuvent être enregistrées avec addEventCallback() attendent la définition d'une bibliothèque.
Suivant la façon dont l’évènement survient, la bibliothèque peut disposer de différentes clefs.
Il y a une clef pour chaque événement:
- Type -- le nom du type d'évènement par exemple SoMouseEvent, SoLocation2Event, ...
- Time -- l'heure courante codée dans une chaîne string
- Position -- un tuple de deux integers, donant la position x,y de la souris
- ShiftDown -- type boolean, true si Shift est pressé sinon, false
- CtrlDown -- type boolean, true si Ctrl est pressé sinon, false
- AltDown -- type boolean, true si Alt est pressé sinon, false
Pour un évènement bouton comme clavier, souris ou spaceball
- State -- la chaîne UP si le bouton est relevé, DOWN si le bouton est enfoncé ou UNKNOWN si rien ne se passe
Pour un évènement clavier:
- Key -- le caractère de la touche qui est pressée
Pour un évènement bouton de souris:
- Button -- le bouton pressé peut être BUTTON1, ..., BUTTON5 ou tous
Pour un évènement spaceball:
- Button -- le bouton pressé peut être BUTTON1, ..., BUTTON7 ou tous
Et finalement les évènement de mouvements:
Afficher les évènements claviers et commandes
Cette macro affiche dans la vue du rapport les touches enfoncées et tous les événements commande
This macro displays in the report view the keys pressed and all events command
App.newDocument()
v=Gui.activeDocument().activeView()
class ViewObserver:
def logPosition(self, info):
try:
down = (info["Key"])
FreeCAD.Console.PrintMessage(str(down)+"\n") # here the character pressed
FreeCAD.Console.PrintMessage(str(info)+"\n") # list all events command
FreeCAD.Console.PrintMessage("_______________________________________"+"\n")
except Exception:
None
o = ViewObserver()
c = v.addEventCallback("SoEvent",o.logPosition)
#v.removeEventCallback("SoEvent",c) # remove ViewObserver
Manipulation de scènes graphiques en Python
Il est aussi possible d'afficher ou de changer de scène en programmation Python, avec le module pivy en combinaison avec Coin
It is also possible to get and change the scenegraph in Python, with the 'pivy' module -- a Python binding for Coin.
from pivy.coin import * # load the pivy module
view = Gui.ActiveDocument.ActiveView # get the active viewer
root = view.getSceneGraph() # the root is an SoSeparator node
root.addChild(SoCube())
view.fitAll()
L'API Python de pivy est créé en utilisant l'outil SWIG. Comme dans FreeCAD nous utilisons certains noeuds (nodes) écrits automatiquement nous ne pouvons pas les créer directement en Python. Il est cependant, possible de créer un noeud avec son nom interne. Un exemple de SoFCSelection, le type peut être créé avec:
type = SoType.fromName("SoFCSelection")
node = type.createInstance()
Ajouter et effacer des objets de la scène
Ajouter de nouveaux noeuds dans la scène graphique peut être fait de cette façon. Prenez toujours soin d'ajouter un SoSeparator pour, contenir les propriétés de la forme géométrique, les coordonnées et le matériel d'un même objet. L'exemple suivant ajoute une ligne rouge à partir de (0,0,0) à (10,0,0):
Adding new nodes to the scenegraph can be done this way. Take care of always adding a SoSeparator to contain the geometry, coordinates and material info of a same object. The following example adds a red line from (0,0,0) to (10,0,0):
from pivy import coin
sg = Gui.ActiveDocument.ActiveView.getSceneGraph()
co = coin.SoCoordinate3()
pts = [[0,0,0],[10,0,0]]
co.point.setValues(0,len(pts),pts)
ma = coin.SoBaseColor()
ma.rgb = (1,0,0)
li = coin.SoLineSet()
li.numVertices.setValue(2)
no = coin.SoSeparator()
no.addChild(co)
no.addChild(ma)
no.addChild(li)
sg.addChild(no)
Pour le supprimer, il suffit de:
sg.removeChild(no)

Ajout de widgets personnalisés à l'interface
Vous pouvez créer un widget avec Qt designer, le transformer en Script Python et l'incorporer dans l'interface de FreeCAD avec PySide.
You can create custom widgets with Qt designer, transform them into a python script, and then load them into the FreeCAD interface with PySide.
Le code python produit par le compilateur python Ui (l'outil qui convertit les fichiers .ui de qt-designer en code python) généralement codé comme ceci (il est simple, vous pouvez aussi le coder directement en Python):
class myWidget_Ui(object):
def setupUi(self, myWidget):
myWidget.setObjectName("my Nice New Widget")
myWidget.resize(QtCore.QSize(QtCore.QRect(0,0,300,100).size()).expandedTo(myWidget.minimumSizeHint())) # sets size of the widget
self.label = QtGui.QLabel(myWidget) # creates a label
self.label.setGeometry(QtCore.QRect(50,50,200,24)) # sets its size
self.label.setObjectName("label") # sets its name, so it can be found by name
def retranslateUi(self, draftToolbar): # built-in QT function that manages translations of widgets
myWidget.setWindowTitle(QtGui.QApplication.translate("myWidget", "My Widget", None, QtGui.QApplication.UnicodeUTF8))
self.label.setText(QtGui.QApplication.translate("myWidget", "Welcome to my new widget!", None, QtGui.QApplication.UnicodeUTF8))
Puis, vous devez créer une référence à la fenêtre FreeCAD Qt, lui insérer le widget personnalisé, et transférer le code Ui du widget que nous venons de faire dans le vôtre avec:
app = QtGui.qApp
FCmw = app.activeWindow() # the active qt window, = the freecad window since we are inside it
# FCmw = FreeCADGui.getMainWindow() # use this line if the 'addDockWidget' error is declared
myNewFreeCADWidget = QtGui.QDockWidget() # create a new dckwidget

PS: Les angles sont affichés en Radian, pour la convertir un radian en degrés faites :
- angle en Degrés vers Radians :
- Angle en radian = pi * (angle en Degrés) / 180
- Angle en radian = math.radians(angle en Degrés )
- angle en Radians vers Degrés :
- Angle en Degrés = 180 * (angle en radian) / pi
- Angle en Degrés = math.degrees(angle en radian)
