How to draw a line by direction and base point3D using C#

Hi,

Is there any function by which we can create an unbound line object by direction and a base point?

The line can be created by two points. Is there any option to create any line by direction also?

Line ln = new Line(BasePoint, SecondPoint);

Thanks in advance

Maybe, you want a Ray?

Hi,

In addition to what @norman.yuan said.

Your question is not very clear. An "unbound line" may be a Ray (which has a start point and extends to infinity in one direction) or an Xline (which extends to infinity in both directions).

Both types have a constructor which take a (start) point and a vector (direction).

A Line is a linear segment which has a StartPoint, an EndPoint and a Length property, so it can't be defined with only one point and a vector.
