Region Grow Line
This command extracts a line according to a seed point and visible objects
Requirements
To extract a line, launch the command and click a seed on objects.
You can force the center or the axis :
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.
The Extraction tolerance corresponds to the extraction of the plane which contains the geometry (Extraction performed in two steps: plane and contour extractions).
