Hi, yes I use join, this task and query was created following Pascals use of Loft on profiles that shared the same rail, saying use matchSrf where a thin gap exists, when I tried matchSrf it wouldnt run as I had trimmed the sharp corner off the loft first. and when I did the matchSrf first it created a gaping hole.
see here for this.
and my storyboard of images partway down.
i have refined the curves since by the way, it still does it !
