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.

How To Use - Version 2
File selection is the same as version 1.5. With version 2 you now have the choice to either have the resulting airfoil made with a Draft Wire (DWire) or a Basic Spline (BSpline). As with version 1.5, you enter the desired chord length. Additionally you can now select which type of foil you want. Simply click on the BSpline radio button or leave as is for for the default DWire.



Version 1.5
Macro_Airfoil_Import_&_Scale.FCMacro

Editing The Default Selection
If you primarily wish to have your imported and scaled airfoils made with BSplines rather than DWires, the Marco may be edited to default to the Bspline. This is done by editing the line -

- and changing it to -

A note on this is included within the text of the macro.
