OdGeCircArc2d::tangent Method (OdGePoint2d&, OdGeLine2d&, OdGeTol&)

Syntax

C++

bool tangent(const OdGePoint2d& point, OdGeLine2d& line, const OdGeTol& tol = OdGeContext::gTol) const;

Parameters	Description
const OdGePoint2d& point	[in] The point on the full circle.
OdGeLine2d& line	[out] Receives the tangent at that point.
const OdGeTol& tol = OdGeContext::gTol	[in] Geometric tolerance.

Returns true if and only if the specified point is on the full circle of this arc, the tangent at that point.
