Coordinates and nerve

Operating system: window7

There are a few questions about using 3D Slicer.

  1. Can I change the coordinates of the model shown in 3Dveiwer before extracting with stl?
  2. Can we match the stl model to the CT and extract the model with its coordinates?
  3. Can I view the 2D viewer as a panorama? Is there a function that can extract nerve in 3D in that state?
