Region Grow Sphere
This command extracts a sphere according to seed points and visible objects.
Requirements
To extract a sphere, launch the command and click a seed on objects.
You can force the radius or the center :
Enter the XYZ coordinates in the edit controls or click on the icon
to click a point in the scene.
Set the Extraction tolerance.
Click a seed point.
Notes
Once a seed point is clicked, the computation is launched. You can cancel the current computation by pressing ESC.
Sometimes, when you compute a geometry, an incorrect extraction may occur with the point you click (ie noisy point). In that case, delete the latest point with DEL and click a new point
You can't lock all the properties at once: prefer the corresponding draw command.
