Hi @mohammed_alshakhas,

Thanks for reaching out.

The segmentation you are displaying may not correspond to the CT currently displayed in the 2D views.

For instance, when loading the CBCT dental surgery sample data, two CTs are loaded at the same time : Post and Pre dental surgeries.

You can change what is displayed from the data module using the eye icon next to the data or the 2D view from the drop down menu :

Probably the segmentation is not being put in the same transform.

there is no transform , and if you noticed it looks compressed and distorted. i did very low quality scans before and was perfect . so im wondering whats the cause for this
