Roof Design
ROOF DESIGN
Roof Design Challange Will consider Assembling of Front roof rail, rear roof rail, Bow roof,Center roof Rail with Reinforcement.
Before Design we need to follow some importent below conditions:-
1. Front and BAck Visbility critiria,
2. Head room clearence ,
3. Mounting of Glass arrangements,
4. Rear end Door Hinge Monting Arrangements,
5. Sunroof to be provided or not,
6.To Satisfy Snow load & Heat Distortion Calculation .
Roof Outer Design:-
Download Given Skin Data for reference and study the master section to understand the requirments.
Prepare the front and rear end flanges as per the master section and provide blends.
Miror the Prepared Surface by Using center datum plane and sew it . if sew operation fails try different Method to repair the surface and sew it again.
Now Thicken the sewed surface by .75 mm thick towards downward direction as per the master section.
FRONT ROOF RAIL:-
Take the reference surface from prepared Outer surface for front roof rail. and prepare the front rof rail operation by using master section.
Sew the surfaces and blend the surfaces.
Mirror the roof rail by using center dartum plane. sew it if fails repair the surface and sew it again.
thicken the surface by .75mm towards upward direction as per master section.
REAR ROOF RAIL:-
Take the required reference surface from prepared outer roof surface.
Start prepare rear roof rail as per the master section by different operation.and mirror and sew it .
Thicken the final surface by .75mm towards upward direction .
BOW ROOF 1&2 DESIGN:-
Take the reference surface from prepared roof outer surface for creating Bow roof design.
here one additional point to consider bow roof to be streight so suface to be trimmed from center dataum plane for creating the surfacess.
Then do different operation to get required surface and sew it and mirror the object.if sew operation fails follow the same repair operation.
IF surface are ready do thicken by .75mm towards upward direction.
Center Roof rail With Reinforcement:-
Take reference surface from the created roof outer surface.
Create the center roof rail and roof rail reinforcement surface as per master section and sew it.
Reinforcement and outer surface flanges to be maintained without any gap because it will spot welded with ditch area .
so both the surface thicken towards the upward direction.
ROOF DESIGN FINAL ASSEMBLY FILE:-
Lets go to assembly file and unhide the all parts and check the over lap surface if any repair it. and cross check the view section to refer master section.

Roof Design Calculations:
Heat Distortion Critiria,
As per Formula we need to derive the values from the object and calculate .if the values less than 2.7 bow positions are ok.
Snow Load Conditions,
Derive the values and measurements from the object as per formula requirements if Qr Value more than 3.1 all the requirements are satisfied.
