update request for CivilSurface.cs

[atultegar]

Hi Paolo,

I have created a node to find out the intersection point between line and Civil surface. The inputs required are

• CivilSurface
• Point (Start point of line)
• Direction vector The Output:
• Point

Also, I have used this node in Dynamo script to create inclined anchors originating from a start point and direction vector (based on inclination angle).

Thanks Atul Tegar
