Hello  
I tried to segment bones in the following scan usung “Threshold”. Unfortunately, it does not display properly in a 3D view. There is only a small 2D visible. What I’ve done wrong?

Please use the latest preview version, where there is a button says ‘Show 3D’, and also a lot of improvements with respect to 4.10.2

Can you reproduce the issue with any of the “Sample data” module’s data sets? If yes then please create a segmentation, save it as a .mrb file (small package icon in Save data window), and share it with us (upload somewhere and post the link here) so that we can investigate further. Thank you!

Thank you for your time and effort. It’s working now - It had to be a temporary problem.
