Week 8 - Challenge 4 - Bumper

1. Bumper
The initial step is to check for any discontinuity in the class A surface model using Join or Boundary option.

Here only the outer boundary line is found. There is no discontinuity between the surfaces.

The next step is to define the tooling direction. Here the Bezel bin is more suitable for defining the tooling axis.

There is an flat face which is on the surface. Extracting that flat face and create a point on the surface. Draw a line perpendicular using that point.

Draft analysis on Class A surface:

Draft analysis is performed on class A surface to check the draft angle's of each faces

Green color on the class A surface denotes- Draft angle 3 degrees and above.
Other codes on the dialog box

Red denotes- 0-3 deg angle

Blue denotes- Less than 0 degree

Class_B_Surface_creation:

Offsetting Class A surface inward some faces were missed while offsetting. Those surfaces were created using multi section, sweep options

Class B is extrapolated from all surface edges to make it intersect with class A+C surface for trim operation.

Class_C_Surface_creation:

Class C surface is used to close class A and Class B to form a closed surface. Class C is created perpendicular to the tooling axis.

Joining Class A& Class C surface and trim with Class B surface to create a closed surface.

CLASS A+C:

Final Closed surface

Creating a solid model:

Using the closed surface option in part modeling to form a solid model.

Draft analysis on the finished component:

Green color denotes- Draft angle 3 degrees and above
Red denotes- 0 degree
Blue denotes- Less than 0 degree
