Can Slicer read the coordinates of the center point of the region that he modeled?  
Let’s say I modeled the kidney ,Can I read what the RAS coordinates are for the center of the kidney region?

Slicer-4.10 returning a swig pointer (such as \_000001bfd4897340\_p\_void) is a minor inconvenience. You can still access the values using the helper function below (in the nightly version the VTK hint is there so the position is directly returned as a Python tuple). def getListFromPointer(bufferPtr, scalarType=vtk.VTK\_DOUBLE, numberOfElements=3): """Con…
