Interior Elevation with multiple wall segments

[inmert]

So I managed to make a button that places interior elevations properly based on boundary segments. But it places a marker for every segment, This works for most rooms but I want to optimize it so it just places one marker for the entire wall which has different segments.

1- Here is what I have

2- Here is what I'm aiming for

Could you check to see if the segments are parallel and then filter? Also using the min and max of all end points to size crop box?
