Tooling axis: -

The tooling axis is created by the point direction method in which the point is the point on the extract of a face and direction is the y-axis of the absolute axis system.

Draft analysis of final part: -

Observing the results of draft analysis, we can say that Class A has draft greater than 3-degree and Class B has negative draft. Class has red, blue and green regions. This is because Class C is generated with 90-degree angle with respect to Class A. Thus, the result related to Class C is expected.

Now for the draft analysis of Heat Stakes and Locators, a draft angle of 0.5 degree is selected as the upper limit.

Here we see that the features are red which indicates that their draft is less than 0.5 degree. At first glance, it can be said that the feature design is not up to the expected parameters and draft angle. But let us lower the draft upper limit just a little in steps and see the draft analysis of the features.

We see that the draft of the features is 0.48-degree, thus, it can be treated as margin of error difference and it can be concluded that the design of Heat Stakes and Locators is acceptable.
