Minimum enclosing circle

Compute the minimum enclosing circle of a point cloud in the plane.

Access methods

8 Toolbar: MinCircle_32x32 

8 Menu: ComputationalCAD † Min. enclosing circle

7 Command entry: CC:HULL:MINCIRCLE

Dialog

Select points:
Select the points for which to compute the minimum enclosing circle.

Specify projection direction [X/Y/Z/Ucs/2Points]:
Select the projection direction.
<X>:             The circle is computed in the global YZ-plane
<Y>:              The circle is computed in the global XZ-plane.
<Z>:             The circle is computed in the global XY-plane. (default)
<Ucs>:          The circle is computed in the UCS XY-plane.
<2Points>:     The circle is computed in a user defined plane perpendicular to the projection direction. The following dialog occurs:

           Specify first point
                     Select the first point of the normal vector defining the plane.
           Specify second point
                     Select the second point of the normal vector defining the plane.

Notes

The 2d enclosing circle is the circle that encloses all points with minimum diameter. If the points are 3d points, the 2d minimum enclosing circle is computed for the projection of these points onto the specified projection plane.
