Parameters 

Description 

const OdGeCurve2d& curve1 

[in] First curve to define a tangent arc.  

const OdGeCurve2d& curve2 

[in] Second curve to define a tangent arc.  

double radius 

[in] Radius of arc.  

double& param1 

[out] Receives the parameter corresponding tangency point on curve1.  

double& param2 

[out] Receives the parameter corresponding tangency point on curve2.  

bool& success 

[out] Receives true if and only if the tan-tan-radius or tan-tan-tan curve could be constructed. If false, this arc is unmodified.
