Problems with importing models from OsiriX

Models created in OsiriX have two problems when imported into Maya: they are 10x too large (see how small and far away the reference grid is in the image below?) and they have abnormal polygon normals, so the surface looks strange in Maya smooth shade mode. 

import OBJ models of skull and mandible into Maya

  • hover mouse over models and press number key 5 for "smooth shade"
  • press 4 to toggle back to mesh view, and then 5 again

these models were made and saved to OBJ format in OsiriX, so they have two problems: they are 10x too large and the polygons have incorrect "normals"

to scale models down to 0.1, shift-select skull and mandible, press button in farthest right top corner of Maya to open Channel Box/Layer Editor, shift select all of the 1s to the right of Scale X, Y, Z, type 0.1 and press enter. Shift-select the scale name attributes, then right click and "Freeze"/scale (this will reset the current scale to cm)
