Door Arm Rest Week 8 Challenge
Challenge 8- Door Arm Rest
Aim: To design the door arm rest Automotive sheet metal component of the car with the help of Generative shape designing of Catia V5.
Objective: To understand the multiple commands and surface designing , also how to form a closed body using the surface designing.
Design Methodology and Requirements:
Design Requirements:
- Tooling Axis
- Class A Surface
- Class B Surface
- Class C Surface
- Closed body
Design Methodology:
Tooling Axis: Tooling axis is created in all three directions i.e. x, y, z,. To design this, we intersected between the required plane and the surface and then by getting intersection curve, we construct lines in the given required direction
Class A Surface:
Class A surface was provided as a skin data with the help of which class B, Class C, and tooling direction is made.
Class B Surface:
- Top surfaces are extracted and untrimmed and then the surfaces are extrapolated to get the intersection.
- Surfaces are created with the help of sweep command and multi sections.
- Surface were offset to 2.5 mm to get the desired thickness
Extra surfaces were trimmed and the required Class B obtained.
Class C Surface
To Create Class C Surface, the straight boundary edges were extracted and the sweep operation performed at angle of 3 degree. The fillet edges were joined using connect command and gap surfaces were filled using multi sections. The gaps filled using extrapolate and trim sheet command.
Join:
The Class A and Class C surface were joined to to properly trim the Class B Surface with the join.
Finally, the join created is trimmed with the help of boundary of Class B Surface and the desired surface is joined using close surface and we get the solid part body.

Conclusion: With the help of this project, I learned about the surface designing using generative shape designing in Catia V5 and analysing various errors and rectify them.
