Scissors tools in 4.10.2 is indeed working. We can help you better if you can describe what is not working in more detail (e.g., your data, steps that you have done prior to scissor, any error message etc)…

</div>

sequence of steps  
loaded sample CTChest  
opened module segment editor  
created two segments  
created a mask by using threshold to seperate out the airways and lungs  
generated a 3d model using grow from seeds  
used segment statstics to generate volume of lung with airway  
tried to use scissors to cut out the lung lobes so that only the airway remains behind , but the scissors wouldnt work  
plz help

Maybe you choose the wrong segment in segmentations list. It is better you can attach the screenshot of every step.  
Best wishes,

@shivaprasad_kolur Please use a recent preview version. 4.10.2 is more than one and a half year old, and an immense amount of stabilization and improvement work has been done in Segment Editor. Let us know if it works for you.

If not, then please elaborate on how the scissors tool did not work. It would also help if we could see a video or something that helps us better to understand the problem.

Without seeing screenshots or screen capture videos, we can only guess. Just a few more guesses:

- You haven’t clicked Apply when you are finished with “Grow from seeds”
- You have chosen masking settings that allow editing the selected segment at the location you wanted to cut
- You have not selected the correct segment (Scissors only cuts the selected segment)
