Week 9 - Attachment Feature Creation - Challenge 2

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.

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_C_Surface_creation:

Class C surface is used to close class A and Class B to form a closed surface.

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

Final Closed surface

Creating a solid model:

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

Draft analysis of finished part:
