Your loop says "#while (360 > 0)" which is always true, so the loop can
never end. This should work:

#declare NT1 = 360;
#declare Tower1 = union {
  cone {
    0*z, .75, 3.25*z, .25
    material {GlassTex1}
  }
  #while (NT1 > 0)  // <= CHANGE
    cylinder {
      <0,0,0>,<0,0,3.288>, .25
      rotate -8.75*y
      translate -.75*x
      rotate NT1*z
      texture{DarkMetal1}
    }
    #declare NT1 = NT1 - 30;
  #end
}
