Automatically rotate CT-scans to be in the XY-plane
« on: November 14, 2023, 10:11:08 AM »
Hello M2M team,

I have a CT-scan of a GDL, but the geometry is not aligned with the global coordinate system in GeoDict (XYZ).
To perform now an accurate flow simulation I need the GDL to be in the XY-plane.
Is there a simple way in the GeoDict image processing to automatically rotate the GDL in the described way?

Best regards,
Erik

Hello Erik,

Yes, there is. In the 3D Image Processing dialog under the Image Processing tab unfold Image Alignment and then Rotation. Select Automatic Rotation and choose Plane from the Automation Mode pull-down menu. When clicking apply the image is automatically aligned with two major axes. If you want to see a preview of the automatic rotation first, you can just click Suggest - Plane and observe the rotation overlay in the 2D visualization of your scan on the right.

Best regards,
Janine
