Week 9 - Challenge 1 - Base Bracket Design

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.

FOR CLASS-B SURFACE:

We can divide the surfaces as shown below. Then we will work on them one by one.

FLAT SURFACE:

1. Extract the flat surface.
2. Un-trim the surface.
3. Extrapolate it.
4. Offset it by 2.5mm i.e. thickness.

SLANT SURFACE:

1. Extract the slant surface.
2. Un-trim the surface.
3. Extrapolate it.
4. Offset it by 2.5mm i.e. thickness.

RIBS SURFACES:

1. Extract the rib surfaces (1 rib at a time).
2. Un-trim the surface.
3. Extrapolate it.
4. Offset it by 2.5mm i.e. thickness.
5. Trim to get the desired shape.
6. Repeat it with the second rib too.

Once we have finished doing this, we have to trim the surface to get exact shape of the class-A surface (without fillet) below 2.5mm. After the trimming part is done, fillet the model. Formula for filleting= fillet value+thickness (if the surface is below). We get our class-B surface.

FOR CLASS-C SURFACE:

1. Extract the boundary of the class-A surface.                                                                         
2. Extract the boundary of the holes on the class-A surface.
3. Use sweep command on the boundaries one by one to get the class-C surface.

FINAL BASE BRACKET:

1. Join the class-A and class-C surfaces together.                                                                     
2. Trim the class-B surface with the join created earlier.                                                                      
3. Go to part design and close the model.
