Week 9 - Challenge 3 - Bumper

BUMPER

A bumper is a structural and aesthetic component located at the front and rear ends of a vehicle. Its primary purpose is to absorb and mitigate the impact force during low-speed collisions, protecting the vehicle's critical components and minimizing damage.

Modern bumpers are designed to enhance safety, improve aerodynamics, and comply with regulatory standards, while also contributing to the vehicle's overall appearance.

Create the B-Class Surface:

· After determining the tooling axis, offset the A-class surface by 3 mm inward to generate the B-class surface.

· If errors occur during the offset due to fillets:

· Delete the problematic fillet surfaces.

· Use the Multiple Extract command to isolate the desired surfaces.

· Apply Extrapolate to extend these surfaces where necessary.

· Recreate the fillets on the extrapolated surfaces to ensure continuity.

Create the C-Class Surface:

· Determine the orientation of the tooling axis relative to the edges of the A-class surface:

· If the tooling axis is perpendicular to the edges:

· Use the Sweep command to create a surface extending outward with a 3-degree draft angle.

· If the tooling axis is parallel to the edges:

· Use the Sweep (With Reference Surface) command to create a surface extending 90 degrees inward to the surface.

· Ensure smooth transitions by maintaining proper curvature during the sweep.

Combine the A, B, and C Surfaces:

· Use the Join command to merge the A-class surface and the C-class surface.

· Trim the joined (A + C) surfaces with the B-class surface to form a single, continuous closed surface.
