XLINE - setSecondPoint is not a member of AcDbXline

[ZK_BUDiKOM]

In XLine Method (http://docs.autodesk.com/ACDMAC/2011/ENU/ObjectARX%20Reference/index.html?frmname=topic&frmfile=AcDb... is "setSecondPoint":

AcDbXline Methods

Why I have an error??
"error C2039: 'setSecondPoint' : is not a member of 'AcDbXline'"

AcDbEntity* AddXline (const AcGePoint3d& firstPt, const AcGePoint3d& secondPt)
{
AcDbXline *pxline = new AcDbXline();
pxline->setBasePoint(firstPt);
pxline->setSecondPoint(secondPt);
(...)
}

How to recount AcGePoint3d& to AcGeVector3d?

AcGeVector3d vec;
vec.x=secondPt.y;
vec.y=secondPt.x;
vec.z=0;
ASSERT(vec);
pxline->setUnitDir(vec);
??

Ok, I write:

AcDbXline *pxline = new AcDbXline();
pxline->setBasePoint(firstPt);
AcGeVector3d vec = (firstPt - secondPt).normalize();
pxline->setUnitDir(vec);
return pxline;

but don't understand, why setSecondPoint is still unavailable even though it is in the documentation...
