Popis

Toto makro vytváří kružnici opsanou 3 vybraným bodům na kolmicích nebo ve 3D zvoleném prostoru. Body mohou být objekty jako jsou krychle, válce,..., potom souřadnicemi budou středy vybraných tvarů.


Kružnice vytvořená podle 3 vybraných bodů

Použití

Vyberte 3 body nebo tvary ve 3D pohledu a spusťte makro.
Je-li tvarem přímka, souřadnicí bude střed přímky.

Circle_on_3_points

Volby

Mód :

Defaut(přednastavený) :

Defaultní mód vytváří kružnici podle 3 bodů nebo tvarů ve 3D prostoru.
Pořadí vybíraných bodů u tvarů ovlivňuje úhly odklonu OS a zpětně odklon kružnice. V případě potřeby se lze vrátit a změnit pořadí výběru tvarů.
Souřadnice X, Y, Z s hodnotou 0 nebo zarovnání, které neumožňuje výpočet, může vrátit chybu dělení nulou se zprávou Tyto tři body jsou vyrovnány

Vue Face :

Vytváří kružnici v nárysu vybraného tvaru, 1, 2 or 3

Vue Dessus :

Vytváří kružnici v půdorysu vybraného tvaru, 1, 2 or 3

Vue Droite :

Vytváří kružnici v bokorysu vybraného tvaru, 1, 2 or 3

Alignement sur :

Forme 1, 2, 3

Tvary podle jejich výběru.

Afficher le centre :

Je-li políčko zakliknuto, bude vytvořen i středový bod kružnice

Associer les couleurs

Je-li políčko zakliknuto, kružnice přebere barvu aktuálního pohledu,
Pohled shora (X,Y) = Modrá(osa Z)
Pohled zepředu (Z,X) = Zelená(osa Y)
Pohled zleva (Z,Y) = Červená(osa X)



Skript

Soubor by měl být zkopírován do " C:/Program Files/FreeCAD0.13/ " Chcete-li jej uložit do jiného adresáře, upravte cestu k němu na řádku 53

         path = FreeCAD.ConfigGet("AppHomePath") # chemin

Tyto tři ikony musejí být ve stejném adresáři jako makro.
