Method 
Description 
This function creates one or more entities that, together, make up the result of offsetting the curve by the distance offsetDist in the plane with normal vector normal. For many curves, the result will be a single new curve, which may not be of the same class as the original curve. For example, offsetting an AcDbEllipse results in an AcDbSpline, since the result of offsetting an ellipse does not fit the equation of an ellipse. However, in some cases it might be necessary for the offset result to be several curves. To allow for this possibility, a dynamic... more 
Returns the base point of the ray.
 
This is secondPoint, a member of class AcDbRay. 
Sets pt to be the base point of the ray.
 
This is setSecondPoint, a member of class AcDbRay. 
Sets vec to be the unit direction vector of the ray.
 
Override this virtual function in a AcDbEntity-derived class to provide your custom implementation for AcDbEntity::subGetClassID Method
Returns the unit direction vector of the ray.
