Hi, I tried to do a new segmentation and the software returned for 4 times with a failed segmentation. I couldn’t also get the 3D reconstruction and I press “Show 3D”

@Andreza this thread is over three years old, and given our conversation in the other one probably your issues are not related to what’s covered here.
Please start a new topic and spell out exactly what you have done and where the error is coming from, the version of the software etc.
