Создание ипортировщика в нового типа файлов в FreeCAD, просто. FreeCAD не считает что вы импортируете данные в открытый документ, а скорее что вы просто можете непосредственно открыть новый тип файла. Так что все что вам нужно сделать, это добавить новое расширение файла в список известных расширений FreeCAD , и написать код, который будет читать файл и создавать FreeCAD объекты: |

===Наблюдение за поведением мыши в трёхмерном окне через Python=== |

Оболочка Inventor позволяет добавить один и более узлов обратного вызова (callback) в дерево сцен просмотрщика. По умолчанию, в FreeCAD на каждый просмотрщик установлен один узел обратного вызова, который позволяет добавить глобальные или статические функции C++. В соответствующих привязках Python предоставляются некоторые методы, позволяющие использовать эту технику из кода Python. |

Introduction
Эта страница содержит примеры, обрывки, куски FreeCAD python кода, собранный для получения пользователями оптыта и обсуждения на форумах. Читайте и используете их как начало для ваших собственных сценариев...
Snippets
Обычный файл InitGui.py
Каждый модуль должен содержать, помимо основного файла модуля, файл InitGui.py, ответственный за вставку модуля в главное Gui. Это простой пример.
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())
Обычный файл модуля
Это пример главного файла модуля, содержащего всё что ваш модуль делает. Это Scripts.py файл, вызываемый в предыдущем примере. Вы можете установить здесь все ваши пользовательские команды.
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())
Импорт нового типа файлов
Создание ипортировщика в нового типа файлов в FreeCAD просто. FreeCAD не считает, что вы импортируете данные в открытый документ, а скорее что вы просто можете непосредственно открыть новый тип файла. Так что все что вам нужно сделать, это добавить новое расширение файла в список известных расширений FreeCAD, и написать код, который будет читать файл и создавать объекты FreeCAD:
Это строка должна быть добавлена в InitGui.py файл для добавления нового расширения файлов в список:
# 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")
Тогда в файле Import_Ext.py:
def open(filename):
doc=App.newDocument()
# here you do all what is needed with filename, read, classify data, create corresponding FreeCAD objects
doc.recompute()
Экспорт вашего документа в новые типы файлов работает схожим образом, исключая того что вы используете:
FreeCAD.addExportType("Your new File Type (*.ext)","Export_Ext")
Добавление линии
Простейшая линия через две точки.
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()
Добавление многоугольника
Многоугольник это просто набор соединенных отрезков (polyline в AutoCAD). Он необязательно должен быть замкнутым.
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()
Добавление и удаление объекта из группы
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
Примечание: Вы также можете добавлять другие группы в группу...
Добавление полигональной сетки
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
Добавление дуги или окружности
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()
Получение доступа и изменение представления объекта
Каждый объект в FreeCAD документе ассоциируется с визуальным представлением объекта, которое хранит все параметры , определяющие как объект представлен, такие как цвет, длина линий, и.т.д... Смотри так же отрывок Перечисление компонентов объекта ниже
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

Наблюдение за поведением мыши в трёхмерном окне через Python
Оболочка Inventor позволяет добавить один и более узлов обратного вызова (callback) в дерево сцен просмотрщика. По умолчанию, в FreeCAD на каждый просмотрщик установлен один узел обратного вызова, который позволяет добавить глобальные или статические функции C++. В соответствующих привязках Python предоставляются некоторые методы, позволяющие использовать эту технику из кода Python.
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)
Теперь, выберите какую нибудь область в окне 3D-просмотра и наблюдайте сообщения в окне вывода. Для завершения наблюдения просто вызовите
v.removeEventCallback("SoMouseButtonEvent",c)
Поддерживаются следующие типы событий
- SoEvent -- Все события
- SoButtonEvent -- Все события клавиш клавиатуры и мыши
- SoLocation2Event -- события 2D перемещений (обычно движение мыши)
- SoMotion3Event -- события 3D перемещений (обычно spaceball)
- SoKeyboradEvent -- события нажатие и отпускание клавиш клавиатуры
- SoMouseButtonEvent -- события нажатия и отпускания клавиш мыши
- SoSpaceballButtonEvent -- события нажатия и отпускания клавиш spaceball
Python функции которые могут быть зарегистрированы в addEventCallback() предлагающем словарь(dictionary). В зависимости от наблюдателя события словарь может содержать различные ключи.
Для всех событий существуют ключи:
- Type -- Имя типа события т.е. SoMouseEvent, SoLocation2Event, ...
- Time -- текущие время в виде строки
- Position -- набор из двух целых чисел как позиция курсорa мыши
- ShiftDown -- логическая(boolean) переменная, true если Shift нажат, в противном случае false
- CtrlDown -- логическая(boolean) переменная, true если Ctrl нажат, в противном случае false
- AltDown -- логическая(boolean) переменная, true если Alt нажат, в противном случае false
Для всех клавишных событий, т.e. для событий клавиатуры, мыши или spaceball
- State -- Строка 'UP' если кнопка была вверху, 'DOWN' если кнопка была внизу или 'UNKNOWN' во всех остальных случаях
Для событий связанных с клавиатурой:
- Key -- значение нажатоой клаывиши
Для событий связанных с мышью
- Button -- Нажаты клавиши, могут быть BUTTON1, ..., BUTTON5 или ANY
Для событий spaceball:
- Button -- Нажатые клавиши, могут быть BUTTON1, ..., BUTTON7 или ANY
и наконец события движения:
- Translation -- набор из трех переменных floats
- Rotation -- кватернион поворота, т.е. набор из четырех переменных floats
Показать нажатые клавиши и команды Событий
Этот макрос отображает в отчете нажатия клавиш и команды всех событий

Манипулирование графом сцен в Python
Возможно так же получить и изменить в Python граф сцен с помощью модуля 'pivy' - привязки Python для 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()
API Python для pivy создано используя инструмент SWIG. Так как мы используем в FreeCAD некоторые самонаписанные узлы, вы не можете создавать их напрямую через Python. Но можно создать узел по его внутреннему имени. Экземпляр типа 'SoFCSelection' можно создать с помощью
type = SoType.fromName("SoFCSelection")
node = type.createInstance()
Добавление и удаление объектов в/из графа сцены
Добавление новых узлов в граф сцены (scenegraph) может сделать таким образом. Позаботьтесь всегда добавлять SoSeparator, чтобы иметь информацию о геометрии, координатах и материалах объекта. Следующий пример добавляет красную линию из (0,0,0) в (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)
Чтобы удалить её, просто введите:
sg.removeChild(no)
Сохранить sceneGraph в 3 сериях из 36 файлов

Добавление к интерфейсу пользовательских виджетов
Вы можете создать собственные виджеты с помощью Qt designerа, превратив их в сценарии на Python, и загрузив их в интерфейс FreeCAD с помощью PySide.
Python код созданный с помощью Ui python compiler (это инструмент для конвертирования файлов ui. созданных qt-designer в python код) в основном выглядит так (это простой пример, вы также может писать этот код напряму с помощью 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))
Тогда все что вам нужно сделать, это создать ссылку на FreeCAD Qt окно, вставить виджет в него, и "преобразовать" этот виджет в ваш с Ui кодом который мы только что сделали:
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
myNewFreeCADWidget.ui = myWidget_Ui() # load the Ui script
myNewFreeCADWidget.ui.setupUi(myNewFreeCADWidget) # setup the ui
FCmw.addDockWidget(QtCore.Qt.RightDockWidgetArea,myNewFreeCADWidget) # add the widget to the main window
Добавить вкладку в Combo View
Следующий код позволяет добавить вкладку к Combo view отдельно от уже существующих вкладок «Модель» и «Задачи». Он также использует модуль uic
для загрузки файла пользовательского интерфейса прямо на этой вкладке.
# create new Tab in ComboView
from PySide import QtGui,QtCore
#from PySide import uic
def getMainWindow():
"returns the main window"
# using QtGui.qApp.activeWindow() isn't very reliable because if another
# widget than the mainwindow is active (e.g. a dialog) the wrong widget is
# returned
toplevel = QtGui.qApp.topLevelWidgets()
for i in toplevel:
if i.metaObject().className() == "Gui::MainWindow":
return i
raise Exception("No main window found")
def getComboView(mw):
dw=mw.findChildren(QtGui.QDockWidget)
for i in dw:
if str(i.objectName()) == "Combo View":
return i.findChild(QtGui.QTabWidget)
elif str(i.objectName()) == "Python Console":
return i.findChild(QtGui.QTabWidget)
raise Exception ("No tab widget found")
mw = getMainWindow()
tab = getComboView(getMainWindow())
tab2=QtGui.QDialog()
tab.addTab(tab2,"A Special Tab")
#uic.loadUi("/myTaskPanelforTabs.ui",tab2)
tab2.show()
#tab.removeTab(2)
Enable or disable a window

- Report view
- Tree view
- Property view
- Selection view
- Combo View
- Python console

mw = FreeCADGui.getMainWindow()

PS: Usually the angles are given in Radian to convert :
- angle in Degrees to Radians :
- Angle in radian = pi * (angle in degree) / 180
- Angle in radian = math.radians(angle in degree)
- angle in Radians to Degrees :
- Angle in degree = 180 * (angle in radian) / pi
- Angle in degree = math.degrees(angle in radian)
