Marko,
I've changed completely the way I calculate the profile.
Used to be Lawson's Walk to get the triangle number.
Now I find the triangle and intersections by exploiting
the return of ssnamex after using the linear entity
as a fence to get the selection set.
Although in version 0.6.2.6 that change was already there.
It is very possible that there is a bug in there.
Will look at it, or maybe you can spot it before me.
I've looked at it too long now, seeing doubles
