Description
This macro creates a circle circumscribed on 3 selected points, orthogonal manner or in 3D at the option space. Points can be objects such as cubes, cylinders,... then selected coordinates will be the centre of these forms.
Use
Select 3 points, or forms in the 3D view and run the macro.
If the shape is a line, the coordinate will be the center of the line.
Options
Mode :
Defaut :
- Mode by default, creates a circle on the three points or shapes in 3d space.
- The order of selection of fear forms influencing the angle AXIS and reverse the inclination of the circle. In this case, reverse or change the order of selection of the shapes.
- Coordinates X, Y, Z value 0 or alignment does not allow calculation, can return a division by zero error, and translated by The three points are aligned
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.

Anaglyphe
Here an Anaglyph view that allows you to see two different positions of the view by using glasses with filters red and Cyan .
