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 vynraných tvarů.
Použití
Vyberte 3 body nebo tvary ve 3D pohledu a spusťte makro.
Je-li tvarem přímka, souřadnicí bude střed přímky.
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 AXIS a 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 výpoče, může vrátit chybu dělení nulou se zprávou Tyto tři body jsou vyrovnány
Vue Face :
- Creates the circle in the front views of the form chosen, 1, 2 or 3
Vue Dessus :
- Creates the circle in the top on the form chosen view, 1, 2 or 3
Vue Droite :
- Creates the circle in the view of right on the form chosen, 1, 2 or 3
Alignement sur :
Forme 1, 2, 3
- Forms, in the order of their selections.
Afficher le centre :
- If this box is checked, a point on the centre of the built circle will be created
Associer les couleurs
- If this box is checked, the circle will take the colour of the relevant view,
- View-Top (X,Y) = Blue(axe Z)
- View-Front (Z,X) = Green(Axe Y)
- View-Left (Z,Y) = Red(Axe X)
-
Circumcircle on 3 forms (front view),
-
in an orthogonal manner on the form chosen (right view)
-
-
Three bystanders orthogonal circles by the form chosen.

Here an Anaglyph view that allows you to see two different positions of the view by using glasses with filters red and Cyan .
Watch alternately with the left eye and the right eye to see the views separately.
