Merge segmented lines

[lrsmns]

is it possible to merge segmented lines into one line?

i have these modellines that serve as room separator lines. However, they are segmented and would like to have it as a continuous line

As an out-of-the-box API command, merging segmented lines isn't directly available. However, you can implement a solution by checking the relationship between the endpoints of the lines and their alignment.

Key Idea:

• Verify if one or both endpoints of the second line lie on the first line.
• If both points lie within the first line, you can omit the second line.
• If one point lies outside, you can extend the first line to include the second.

See this pseudo code, not even tested, but just an example to make the idea close:

public static bool PointOnLine(XYZ p1, XYZ p2, XYZ tp, double tolerance = 0)
{
    var ab = Math.Round(p1.DistanceTo(p2), 4);
    var ap = Math.Round(p1.DistanceTo(tp), 4);
    var pb = Math.Round(p2.DistanceTo(tp), 4);

    if (Math.Abs(ab - Math.Round((ap + pb), 4)) <= tolerance)
        return true;

    return false;
}
