A detailed report should be done explaining the draft analysis and the tooling axis creation

Draft analysis on Class A surface-
Step 1- Open draft analysis and move the compass to coincide with the Tooling axis as below

Step 2- Lock the compass and check the radius using the running analysis option-

Step 3- Set the color code for the draft angle i.e green for above 1-3 degrees, Blue for 0 degrees, and red for angle value lesser than 0.

Step 4- Click on the surface using light effect, if the color goes green throughout means your draft analysis is good and ready for manufacture-

Using Class A surface creating B and C surfaces, and publishing same can be observed from tree structure of the below screenshot-
First tooling axis-

2-An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method.

ANS- Tooling Axis-

Now creating the tooling axis by using bisecting line and a dummy axis-
1. open the file which contains the Class A surface, after creating a geometrical set "Tooling Axis" then select the most appropriate position, and in this select a base of the tab/pocket.

2. Then create a point at the surface extracted then draw a dummy line on the z-axis.

3. After that create a plane on the point created with reference to XY plane direction.

4. Then select the intersect tool that gives the intersection on the Class A surface.

5. Now create 2 lines using the point and direction method as shown below screenshot.

6. the Last step creates a bisecting line using the above 2 lines.

Now creating Side Core Axis-

Creating B and C surface-

B and C surface-

Final Output surface which will be getting solid -

Now creating DOg House using design Rules and given data-

Now Draft analysis on final output-
