Macro Airfoil Import & Scale/cs

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.

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.



Latest
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.

Version 1.5

Macro_Airfoil_Import_&_Scale.FCMacro


 * 1) This Macro, when run, will first provide the user with a file browser to
 * 2) locate and select a .dat airfoil text file. Once selected, a chord length is
 * 3) entered and upon pressing the OK button, a properly scaled airfoil is
 * 4) produced. There are two versions provided here. Version 1.5 should work on
 * 5) FreeCAD versions, 0.13 stable as well as all 0.14 versions. Version 2 should
 * 6) only be used with FreeCAD versions equal to or greater than 0.14 3077 and
 * 7) will work best with versions built with OCE/OCC versions 6.7 or greater (See
 * 8) the Wiki page for all available version).

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 -
