REPORT

1) DRAFT ANALYSIS:

CLASS A SURFACE:

From the draft analysis on class A surface, it is very evident that all the top surfaces are greater than 3 degree.

This is concluded with the green color.

Final Plastic Component:

Initially, when i gave 3 degree on the x-axis (zx surface) dummy tooling axis, the draft analysis showed one surface as blue, indicating that the draft is less than 3 degree.

Later, I updated the sketch with an angle 6 degree so that the surface which has draft lesser than 3 degree (blue surface) turned to green indicating the draft is greater than 3 degree. Hence it is feasible to manufacture.

2) TOOLING AXIS:

Initially for YZ surface, i created a dummy tooling axis.

I used the walls to create a bisecting line ( Dummy Axis 1).

Same image without Class A surface:

Then for XZ surface, as it contained only one wall, I projected it and then created a dummy axis at an angle of 3 degree initially. Later in draft analysis i found that the surface was in less than 3 degree region.

Hence i increased the angle to 6 degree.

Same image without the Class A surface.

Using the above two dummy axis i create, main tooling axis by bisecting the two dummy axis, which i create initially.
