Hi Alberto Usually that means that you missed some cuts and there are still attachments. Occasionally it is due to a local minimum. You can try changing the distance preservation matrix to be bigger with longer range distances. Something like -distances 20 20 (out to 20 neighbors and 20 at each distance) or even largely. The defaults were set a long time ago when there was much less ram available. You can also try -dilate 1 to dilate the cuts by 1 vertex, although then you lose more of the surface
