Volume measurement on imageJ


I am trying to analyse microCT scans using imageJ. I would like to be able to isolate some areas in the 3D viewer and be able to measure their volume.
I have tried to “cut out” the outer part by selecting and area and then choose “fill selection” as suggests the video on the 3D viewer user guide. However, instead of cut out the selected area as in the video, it fills it in white .
If you know how to solve this or know a plug in that could do this that wouls help a lot

Thank you

Thanks for the reply.
It doesn’t reallysolve the problem. I am working in the 3D viewer and the “full selection” by right clicking on the selection fills it with the sample color and not in black. When I change the color foreground (edit menu of the Fiji menu), it on affect the filling color of my stack view.
The “change color” option (edit menu in the 3D viewer), only allows me Tom change my sample color.
I am not sure this is clear enough, I can send pictures if someone can help me with this :slight_smile:
Thank you
