Here is the result of my bronchi after using the LungCT segmentation. May I ask how can I manually connect the small spaces and also make the model display better? This is 0.5mm thickness and I have no idea why the subbronchi doesn’t display here.

You can always use the segmentation editor to manually edit segmentations, either painting the voxels you want or using the more advanced editor tools.

Thank you so much, I think it works much better after I use the AI tools
