Hi Doug!
Thanks for answering! I checked my pickTolerance and I saw that I was using
the default value(2.0). But even though I try set it higher my picking (of
lines) still not work.
I have included some of my code. Maybe I�m doing something wrong somewhere?
Thanks for helping me.

public void mouseReleased(MouseEvent e){
if(e.isControlDown()==true) {
int mouseX = e.getX();
int mouseY = e.getY();
//Get the eye position in view space
Point3d eyePos = new Point3d();
_canvas.getCenterEyeInImagePlate(eyePos);
//Translate the mouse canvas position to view position
Point3d mousePos = new Point3d();
_canvas.getPixelLocationInImagePlate(mouseX, mouseY, mousePos);
//Get the view-to-world transform
Transform3D xform = new Transform3D();
_canvas.getImagePlateToVworld(xform);
//Transform eye and mouse from view to world space
xform.transform(eyePos);
xform.transform(mousePos);
//Save the world pick ray origin
_rayOrg.set(eyePos);
//Build the world pick ray direction
_rayDir.sub(mousePos, _rayOrg);
_rayDir.normalize();
//Set the the origin and direction on the PickRay object (_ray)
_ray.set(_rayOrg, _rayDir);
System.out.println("vector: " +_rayDir.x + ";" +_rayDir.y + ";"
+_rayDir.z);
//PickTool picktool = new PickTool(_branchgroup);
PickCanvas pickCanvas = new PickCanvas(_canvas, _branchgroup);
pickCanvas.setMode(pickCanvas.GEOMETRY);
pickCanvas.setShapeRay(_rayOrg, _rayDir);
pickCanvas.setTolerance(4.0f);
PickResult result = pickCanvas.pickAny();
//_results = _branchgroup.pickAny(_ray);
if(result == null){
System.out.println("No hits");
}
else{
Node shape = result.getObject();
System.out.println("Real hit");
System.out.println("Object: " +shape);
}
}
}//end mouseReleased()
