Roof Design
ROOF DESIGN
An automobile roof or car top is the portion of an automobile that that sits above the passenger compartment, protecting the vehicle occupants from sun, wind, rain, and other external elements.
The automobile roof consists of flowing parts:
- The outer panel
- Front roof rail
- Centre roof rail
- Rear roof rail
FRONT ROOF RAIL:
The front rail is created at the front side of the roof to provide strength to the roof. Headroom clearance and the driver visibility are the two important factors to be considered while designing the front roof rail is connected to the roof outer panel with the help of mastic seal.
BOW ROOF 1 :
It is used to give strength to area between the front roof and the centre roof rail. Also it is created in the area between the centre the centre roof rail and the rear roof rail to provide enough strength. It can crated in any numbers depending upon the roof length but the position of the bow roofs is to be justified by curvature study.
CENTER ROOF RAIL:
It is created at the centre of the roof. It is connected to the roof by mastic seal.
REAR ROOF RAIL:
It is created at the rear end of the roof. The fitment of the backdoor is to be considered while designing the rear roof rail.

DRAFT ANALYSIS:
In NX to check whether the sheet metal part we have designed can be deep drawn, there is an option called draft analysis. This type of analysis is performed based on colour ranges identifying zones on the analysed element where the deviation from the draft direction at any point, corresponds to specified values.
