Popis
Toto makro při spuštění nejprve poskytne uživateli souborový prohlížeč, který vyhledá a vybere textový soubor profilu dat .dat. Po zvolení se zadá délka akordů a po stisknutí tlačítka OK se vytvoří správně měřítko profilu. K dispozici jsou zde dvě verze. Verze 1.5 by měla pracovat na verzích FreeCADu, 0.13 stabilních i všech verzích 0.14. Verze 2 by měla být použita pouze s verzemi FreeCAD rovnajícími se nebo vyššími než 0.14 3077 a bude fungovat nejlépe s verzemi vytvořenými s verzemi OCE / OCC verze 6.7 nebo vyšší.

Jak používat - verze 1.5
Vyberte soubor
Spuštění makra nejprve zobrazí uživateli prohlížeč souborů, který vám umožní vybrat požadovaný soubor datového souboru. Projděte si, kam jste uložili soubor profilu, vyberte jej a stiskněte Otevřít.
Zadejte délku chordu
Po výběru souboru profilu se objeví nové dialogové okno s žádostí o délku akordů. Může být zadána libovolná délka, v milimetrech. Po zadání požadované délky vytvoří makro předběžný vodič (DWire) podle bodů popsaných v dříve vybraném souboru profilu .dat v měřítku, které jste zadali pro délku akordy.
Křídlový profil, správně měřítko, by nyní měl být ve vašem projektu připraven k použití.
Jak používat - verze 2
Volba souboru je stejná jako verze 1.5. S verzí 2 máte nyní možnost mít buď výsledný profil vytvořený pomocí DWire nebo Basic Spline (BSpline). Stejně jako u verze 1.5 zadáte požadovanou délku. Dále můžete vybrat, který typ fólie chcete. Stačí kliknout na přepínač BSpline nebo nechat jako výchozí DWire.

The latest version of the macro is to be found at AirfoilImportAndScale.FCMacro but the easiest way to install this macro is through the Addon Manager.

# This Macro, when run, will first provide the user with a file browser to # locate and select a .dat airfoil text file. Once selected, a chord length is # entered and upon pressing the OK button, a properly scaled airfoil is # produced. There are two versions provided here. Version 1.5 should work on # FreeCAD versions, 0.13 stable as well as all 0.14 versions. Version 2 should # only be used with FreeCAD versions equal to or greater than 0.14 3077 and # will work best with versions built with OCE/OCC versions 6.7 or greater (See # the Wiki page for all available version). # # (c) quick61 __Name__ = 'Airfoil Import and Scale' __Comment__ = 'Imports and scales an Airfoil in the form of a Draft Wire (DWire) or Basic Spline (BSpline)' __Author__ = "quick61" __Version__ = '2.1.2' __Date__ = '2019-07-16' __License__ = '' __Web__ = "http://forum.freecadweb.org/viewtopic.php?f=22&t=5554" __Wiki__ = "http://www.freecadweb.org/wiki/Macro_Airfoil_Import_%26_Scale" __Icon__ = 'https://www.freecadweb.org/wiki/images/0/0c/Macro_Airfoil_Import_%26_Scale.png' __Help__ = '' __Status__ = 'stable' __Requires__ = 'Freecad >= 0.14.3706' __Communication__ = '' __Files__ = '' import FreeCAD as app import PySide from PySide import QtCore, QtGui from PySide.QtGui import QLineEdit, QRadioButton import Draft import importAirfoilDAT # Select .dat airfoil data file to be imported # PySide returns a tuple (filename, filter) instead of just a string like in PyQt global filename global nameFile try: filename, filefilter = QtGui.QFileDialog.getOpenFileName(QtGui.qApp.activeWindow(), 'Open An Airfoil File', '*.dat') except Exception: param = FreeCAD.ParamGet("User parameter:BaseApp/Preferences/Macro")# macro path path = param.GetString("MacroPath","") + "/" # macro path filename, filefilter = PySide.QtGui.QFileDialog.getOpenFileName(None, "Open An Airfoil File", path, "*.dat") nameFile = filename.split("/")[-1][:-4] class AirfoilImporterAndScaler(): def __init__(self): self.dialog = None self.s1 = None # Make dialog box and get the scale size self.dialog = QtGui.QDialog() self.dialog.resize(350,100) self.dialog.setWindowTitle("Airfoil Import & Scale") la = QtGui.QVBoxLayout(self.dialog) t1 = QtGui.QLabel("Chord Length") la.addWidget(t1) self.s1 = QtGui.QLineEdit() la.addWidget(self.s1) # Add radio buttons to select between DWire and BSpline self.radio1 = QtGui.QRadioButton("Make DWire") self.radio2 = QtGui.QRadioButton("Make BSpline") # set default to DWire & make radio buttons - Change self.radio1.setChecked(True) to # self.radio2.setChecked(True) to set BSpline as default self.radio1.setChecked(True) la.addWidget(self.radio1) la.addWidget(self.radio2) # Add OK / Cancel buttons okbox = QtGui.QDialogButtonBox(self.dialog) okbox.setOrientation(QtCore.Qt.Horizontal) okbox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok) la.addWidget(okbox) QtCore.QObject.connect(okbox, QtCore.SIGNAL("accepted()"), self.proceed) QtCore.QObject.connect(okbox, QtCore.SIGNAL("rejected()"), self.close) QtCore.QMetaObject.connectSlotsByName(self.dialog) self.dialog.show() self.dialog.exec_() def proceed(self): global filename global nameFile if self.radio1.isChecked(): try: # This produces a scaled Airfoil with a DWire scalefactor=float(self.s1.text()) f1=str(filename) importAirfoilDAT.insert(f1,"Unnamed") try: Draft.scale(App.ActiveDocument.ActiveObject,delta=App.Vector(scalefactor,scalefactor,scalefactor),center=App.Vector(0,0,0),legacy=True) except Exception: Draft.scale(App.ActiveDocument.ActiveObject,scale=App.Vector(scalefactor,scalefactor,scalefactor),center=App.Vector(0.0,0.0,0.0),copy=False) App.ActiveDocument.ActiveObject.Label = nameFile + "_(DWire)" except Exception as e: app.Console.PrintError("Error, not a valid .dat file\n") if self.radio2.isChecked(): try: # This produces a scaled Airfoil with a BSpline scalefactor=float(self.s1.text()) f1=str(filename) importAirfoilDAT.insert(f1,"Unnamed") points = app.ActiveDocument.ActiveObject.Points App.getDocument("Unnamed").removeObject(App.ActiveDocument.ActiveObject.Name) Draft.makeBSpline(points, closed=True) try: Draft.scale(App.ActiveDocument.ActiveObject,delta=App.Vector(scalefactor,scalefactor,scalefactor),center=App.Vector(0,0,0),legacy=True) except Exception: for i in range(len(points)): Draft.scaleVertex(App.ActiveDocument.ActiveObject, i, App.Vector(scalefactor,scalefactor,scalefactor), App.Vector(0.0,0.0,0.0)) App.ActiveDocument.ActiveObject.Label = nameFile + "_(BSpline)" except: app.Console.PrintError("Error, not a valid .dat file\n") try: # delete the directory created by importAirfoilDAT for obj in App.ActiveDocument.Objects: if (obj.TypeId == "App::DocumentObjectGroup") and (obj.Name == nameFile): App.getDocument("Unnamed").removeObject(nameFile) except Exception: None self.close() # close the window def close(self): self.dialog.hide() AirfoilImporterAndScaler()

Úprava výchozího výběru
Pokud si přejete, aby vaše importované a zmenšené profilové lišty byly vytvořeny s BSplines spíše než s DWires, Marco může být předem nastaven na Bspline. To se provádí úpravou řádku -
##exampleCode## self.radio1.setChecked(True)
- a změnu -
##exampleCode## self.radio2.setChecked(True)
Poznámka k tomuto je obsažena v textu makra.
