Alignment with a Line or P-line Feature

There are two cases to consider:

• Selected line feature is orthogonal to the line of movement

If the line selected line feature is orthogonal to the line of movement, then the feature line is treated as a feature point. Any position along the feature line projects onto the same point on the movement line.

• Selected line feature not orthogonal to the line of movement

If the line selected line feature is not orthogonal to the line of movement, then the intersection of the extended feature line with the line of movement becomes the new Model Editor Handle origin position. If the extended feature line and the movement line do not intersect in 3D, then the point chosen is the nearest point on the line of movement to the extended feature line.
