Line.project returns a point that is not on the line.

[Anonymous]

I have a similar function in my code and I assume it will always return 0 - since <p> is on <line>- , but that is not always the case.

can someone help me understand what I am missing.

double func(Line line)
{
    // line is unbounded
    XYZ p = line.Project(new XYZ(0, 0, 0)).XYZ;
    return line.Distance(p);
}

 Thank you.

Line.Project returns an IntersectionResult. 

I do not see any XYZ property among its members.

Should you not be using the XYZPoint property instead?
