object sliced different direction than placement

I've created a topless and bottomless box to use as a test for print quality for different speeds. The box was created on fusion 360 with the walls vertical and the open bottom down. I've chosen "make", "utility", Repetier-Host and that sends the box to a newly opened Host. When the box is placed in Host from its .STL file, it is placed with two walls vertically aligned and one wall as a bottom and the other wall as a top. That's 90 degrees rotation from the way it was designed on Fusion. I then rotate the box 90 degrees on the X axis which shows it in the same orientation as the fabrication design. When I then try to print it, there is no G-Code shown. When I go to G-Code edit, there is no G-Code shown. So, I go to Slicer, use Cura Engine to slice it and get: 

1 ; Generated with Dura_SteamEngine 15.-1
2 ;  Default start code
3 g28
4 G1 Z15 F100
5 M107  ;  Turn off fan
6 G90   ;  Absolute positioning
7 M82  ;  Extruder in absolute mode
8 M190 S50
9 ;  Activate all used extruder
10 M104 T0 S210
11 G92 E0  ;  Reset extruder position
12 ;  Wait for all used extruders to reach temperature
13 M109 T0 S210
14 ; Layer count: 50
15 ; Layer:0
16 M107
17 ; Layer:1
18 M106 S127
19 ; Layer:2
20 M106 S127
21 ; Layer:3
22 ; Layer:4
then consistent single digit increases in op nos. and Layer nos. til--
67 ; Layer:49
68 M107
69 G1 F2400 E-4.00000
70 G0 G9000 X0.000 Y0.000 Z15.000
71 ; Default end code
72 ; G1 X0 Y0 Z130  ; Get extruder out of way. Uncomment to use!
73 M107  ; Turn off fan
74 ' Disable all extruder
75 G91  ; Relative positioning
76 T0
77 G1 E-1  ; reduce filament pressure
78 M104 T0 S0
79 G90  ;  Absolute positioning
80 G92 E0  ; REset extruder position
81 M140 S0  ;  Disable heated bed
82 M84  ;  Turn steppers off
83

At that point, I go to Print Preview and hit the Print button. The display shifts to Manual Control, the heating starts on printing bed and then to extruder until the printing temps are reached. At that point printing routine starts and takes roughly 9 seconds to complete with an ETE displayed on the LCD screen and the bed and extruders start their cooling phase. So any info as to what I'm bypassing or missing or don't understand or ??? would be appreciated.

Printer is cheap CTC i3 Prusa clone using 1.75 PLA filament, 50* bed temp and 210* extruder temp, Host V2.0.5

      When ETE is displayed on LCD and cooling starts, there has been no movement on any axis, no filament was extruded and now actual printing was done...  nothing.

    You need a volume to slice an object not some walls. I guess you also see a warning about non manifold onject. It is normal that this does not work. Make a big cube and subtravt a smaller cube so that wall thickness is at least extrusion width and it should show up when being sliced.

    will give that a try. thanks for that logic!!
