Week 8 - Challenge 2 - Base Bracket Design

METHODOLOGY:

In this model we have focused on the following things.

1. Tooling axis
2. Draft analysis
3. Class-B suriace
4. Class-C surface
5. Making a solid model from surface

FOR TOOLING AXIS:

1. First ensure the class-A surface is properly joined and has no discontinuity on it.
2. For this we can use boundary command or join command.
3. Analyze the model manually or visually to see which direction is most suitable for tooling axis.

As in 3D view we can see 2 holes and a flat surface, we can directly take the tooling axis perpendicular to that. But to be sure,let us analaze from all the views. The below images of the front side and top views shows the areas that we have to keep in mind while choosing tooling axis. As from X we cannot see one hole so we cannot take axis along this. In Y we cannot see any holes so here too we cannot take tooling axis. But in Z we can see 2 holes and flat surface so we can take tooling axis.

Creating Class B surface

Creating Class C surface

Joining Class C with Class A surface

Trimming Class A& Class C with Class B surface

Closed Surface

FOR DRAFT ANALYSIS:
1. Go to insert< analysis< feature draft analysis.
2. Align the tooling axis with the compass.
3. Click on the surface and see that the surface is within the permissible limit of the draft values.
4. The surface should be green and in the column proper value (3deg) should be inserted
