Substracting Volumes

[[Na...]]

Hello everybody. I am quite new into Zeiss Inspect Xray 2025 Pro and after many unsuccessful tries i am addressing to this forum hoping that someone could help me.

I have two Volume data acquired with Zeiss Metrotom 800. I would like to align this two datasets first using a best fit and then make a Volume difference between them which should result in a new Volume. Of course i have tried different options, Meshing the volume at least for the alignent. WQould also love to Create a volume region from the part and maybe then the substraction works...at least in this direction i am going but still , alignment is a pain. I know volumes can not be aligned and i just need a mesh for Cad but still, any work around would be great. 

Can someone tell me a viable option that works?

Thank you in advance.

 You can align a volume to a CAD, see screenshots. If you do not have a CAD to align your volume, create a mesh from your volume, align that normal to the global axes using a 3-2-1 alignment, and then turn the actual mesh into a "CAD". Once you do that, delete the 3-2-1 alignment and the CAD stays oriented normal to the axes. From this, do an initial alignment>prealignment (volume). Now your volume is aligned normal to the axes so you can clip through normally.

thank you for your answer. now i have a CAD generated from the Volume 1 mesh (actual to CAD)  that is aligned with 3-2-1 to the global axis. The volume 1 is still somewhere else(doesnt follow the mesh). Nevertheless, i still have a Volume 2 with coresponding Mesh and no alignment. How do i align the Two volumes, or the Two meshes, or CAD to Mesh so that in the end I get some aligned data from this two different Volumes (same part, measured at different time intervals) so that i can make a volume difference (substraction) Volume 1 - Volume 2 to be able to extract the difference (volumetric) as a new Volume which is my end goal?

Best regards,

 I am not sure I am following exactly what you are trying to do, but after creating the "CAD" you align the volume to the "CAD" by doing an initial alignment>prealignment (volume).
