title: extrusion lost when importing kmz to google maps
body: <p>I'm importing a .kmz file into google maps, however google maps only displays a 2D projection of the path and seems incapable of displaying variation in altitude. Is that simply a limitation of the program, or is there a way to retrieve and present the height (typically displayed as a transparent vertical green rectangle with vertical yellow bars running through it in google earth)?</p>
  
  <p>Thanks</p>
