I want to import the scene in a project but when I import it I don’t know how to edit it, the segmentation is in the 3D view but I can’t edit because I’m not finding it in the segment editor as a new segment. I want to make a new segment whit the scene I previously saved.

You need to select a master volume in order to edit a segmentation. Follow these instructions: [3D model to segmentation](https://discourse.slicer.org/t/3d-model-to-segmentation/5135/2)
