Barn 3D Model with Rooster Vane Pick

Stylized barn is built in lower and 

upper sections that fit together. 

Corrugated style roof adds detail for both main hull 

and turret-style loft with cutout overlays for all walls. 

See-through window and door openings have 

frame beam overlays with nail head "show-thru" detail. 

Measure approx. 5" wide x 6" long x 8.75" tall. 

Sturdy construction allows this decoration to be used 

and stored for repeated enjoyment.

Barn 3D Model is hown here with 
the slightly-oversized Rooster Weather Vane Pick 

inserted through loft roof and anchored at bottom. 

(Assembly steps for Rooster Weathervane can be found
by following this LINK to a separate tutorial.)

ASSEMBLY: 1. Identify and cut the shapes for BARN:
(NOTE: during testing, some shapes were modified
from the shapes shown in this layout*)
A roof main shape with separate back add-on back panel
B gable beam accent with contrast show-thru (2 sets)
C roof base   D corrugated roof panel
E loft turret main shape with accent overlays
F loft roof base   G loft corrugated roof panel
H loft window frame accents (2)
I Main hull shape with separate side, back add-on panels
and front, back and side overlays
J door frame accents and contrast underlays (2 sets)
*K corner triangle post reinforcements for main hull (4)
L main hull bottom reinforcement panels (3)
M & N side, front/back interior reinforcement panels (6 each)
*O roof interior support panel
NOT SHOWN: hull rim interior reinforcement strips (see step 10),
corrugated roof tab covers (see step 36) for main and loft roofs.

2. Layer the accent card stock beams and door shapes

(with the nail head cut out details) over the "show-thru"

darker accent and glue together.

NOTE: The coloration of the cut file shows

the "base" show-thru layer of both layers of

BOTH shapes as the same grayish color.

The bottom layer needs to be contrast to show thru.

3. Prepare the main barn hull base shape by

bending back on all panel and flange perforation

lines. Also bend back the side flanges on the front/back

separate add-on panel.

4. Position the separate side and front/back panels
in position to attach on the main hull shape,
then overlap the appropriate straight edge over
corresponding flange to perforation line
and glue in place to create the complete hull.

5. Position each of the sides or front/back accent

panels over the corresponding panels on the hull shape

with .125" offset margin all around, and attach in place.

6. Position and attach the layered door unit accents
over the front and back panel door openings
and glue in place.

7. Layer and attach the 3 base reinforcement shapes

into one stack, taking care to align all cut edges

as closely as possible.

(It is recommended to use 'dry' tape roller style

adhesive to avoid warping and curling of the stack.)

8. Invert the hull assembly face down on work surface,

then position the reinforcement stack over

the bottom panel, centered, with even tiny offset

margins all around.

9. Bend two adjacent walls back into position

to overlap the straight wall edge over the adjacent

flange to perf line, and join corner seam.

Repeat to join remaining corner seams.

10. Position and attach the hull rim strips along
their corresponding wall upper edge,
centering side to side along the wall edge.
Take care to align strip and wall upper edges
as precisely as possible.

11. (NOTE: the corner post reinforcement shapes

were modified in the final cut file to be shorter and 

have a straight-cut top end.)

Prepare the post shapes by bending back on

all of the vertical perforation lines.

12. Identify the flange panel that includes the 'F'
cut mark, then form the shape into a triangular tube
with the flange directed under the opposite panel
with straight panel edge overlapped to
perf line, and glue in place.
NOTE: it may be helpful to insert a narrow dowel,
knitting needle or equivalent inside the tube
to provide a "press-against' surface during
the seam gluing process.

13. Layer and glue together the 3 duplicate shapes 

for each of the front, back

reinforcement panels to create stacks.

NOTE that the front and back panel doorway bottom

frame was modified in the final file to NOT be closed.

Repeat the stacking process described above
for the two side reinforcement panel stacks.

14. Glue the corner posts into the interior corners

of the barn hull, placing the right angle corner

 edges toward the hull corner angle,

and taking care that the post bottom end is seated

fully down onto the hull layer within

the triangle recess created there by the absent

corners of the base reinforcement stack

shown in Step 7 above.

15. Prepare the main roof shape by bending back

on all perforation lines for panels and tabs.

16. Position the separate front/back shaped panel

along the tab opposite the connected shaped panel

in mirror image, overlapping the straight edge over

the corresponding tab to perf line, adjust end to end

to make sure edge angles align with panel ends,

and glue in place.

17. Position the beam accent units over the front
and back angled panel, with edges even where
they correspond, and glue in place.

18. Bend the tab flanges down, roof panels into position

to align the first perforation angled edge with corresponding

straight edge and glue in place. Then . . . 

. . . continue to bend the next section into position
to align and attach the next two segments
to corresponding roof tabs.
Repeat for the opposite end of this same angled
seam series, and also for the opposite end panel.

19. Prepare the loft structure main shape by

bending back on all panels and long tabs,

but bend bottom edge long tabs forward.

20. Position (red) accent panels within each
panel, with offset margin all around, window
opening edges matched.
Also position and attach the window opening
frames.

21. Form the loft into a tube to overlap the straight

edge over the opposite flange to perf line,

and complete side seam.

22. Fold the gable edge tabs inward,
then bend the roof half with top edge flange
inward and glue to flange tabs underneath.
Bend second roof half into place and glue sides
and top edges to flange tabs underneath.

23. Prepare the loft roof base panel by

bending back on center perforation line.

24. Prepare the loft corrugated roof shape by

bending in accordion formation, beginning

with end flange folded back on perforation line

as "mountain" fold, then bend the next perforation line

back as "mountain" fold as well.

Bend the next perforation line in as "valley" fold

(including the attachment tabs).

Continue across to bend in alternating order,

except for final two perf lines which are bent back

as "mountain" folds (including the opposite

end flange).

25. Bend the corrug. roof section center tabs

toward backside, then insert into the centerline

slots of roof base section.

On backside of base, bend inserted tabs flat

to touch base backside, and glue in place.

26. Repeat the tab insertion process from step 5

to insert the second row of tabs into the corresponding

roof base slots, and attach underneath.

Turn the assembly to complete the third set of

tabs of corrug. roof into corresponding slots,

and glue in place.

27. At each end of assembly, bend the end flange

around base edge, making sure that roof base edge

stays snugly along the corrug. bend perforation.

28. Push the loft structure through "window" in

main roof structure, and slide loft fully into position

so that roof edges seat along loft bottom flange perf lines,

then . . . 

. . . glue bottom flanges in place.

28. Prepare the roof interior support panel
by bending forward all side flanges.
NOTE this shape has been slightly modified
at corners in the final cut file, as is shown
in next frame.

29. Insert the support panel into the bottom

opening of the roof unit, slide inward until edges

align, then glue in place.

30. Prepare the main corrugated roof panel

in similar manner to the loft roof panel in Step 24,

including bending the end flanges back with

"mountain" fold.

31. Prepare main roof base panel by bending

back on all perforated lines.

32. Insert the center tabs into corresponding

center slots of roof base panel,

and glue to underside as in Step 25.

Then continue to bend corrugated panel into position

to insert mid-way tabs, second angle tabs, etc.

until all tabs have been inserted into their slots

and glued into place.

Also bend the end flanges around roof base edges

and glue into place.

33. Slip the roof panel assembly over the loft

structure and into position, and thoroughly attach

in place.

34. Position and attach loft roof section,

centering front to back.

35. If needed (check to see if the corrugation fold

is resting on the roof base section near ends) . . . 

. . . carefully apply a dab of quick-grab glue between
the corrugated panel and the base panel,
then apply pressure until it is connected in place.

36. To cover the corrugated roof tab openings,
position and attach the smaller cover tabs over
loft roof, and larger tabs over main roof.

37. Assemble the barn by placing the roof assembly
over the barn hull, with side reinforcement top edges
tucking inside roof.
NOTE: if you wish to have the barn remain a "box",
this connection can remain un-glued.
For best results, it is recommended that the roof unit
be glue-attached to the base.

38. If desired, prepared and insert 

Rooster Weather Vane accent post "stick"

through opening in loft roof, through

the roof support panel (look through door openings

to "fish" the end around until it inserts through hole)

then seat end into the round depression

in the hull bottom reinforcement panel center.

(Glue in place if possible.)

Here is the finished barn project.
