Challenge: Week 8 - Challenge 2 - Switch Bezel Design
1- A detailed report should be done explaining the draft analysis and the tooling axis creation.
Draft analysis on Class A surface of Switch Bezel below-
Step 1- Open draft analysis and move the compass to coincide with 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 3 degrees, Blue for 0-3 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-
Now Creating Class B and Class C surface for switch Bezel-
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.
Have a look at the Screenshots
The above line is made for the Y direction and making the line for the X direction with the same procedure used above
But in this, we need to draw a line manually and keep its angle to 6 degrees-
The final step for the Tooling axis -
Bisect the lines created in sketch 9 and sketch 11 using the bisecting line command-
Color it yellow and published it.
Creating Class B surface-
1- BEZEL REST SURFACE-
2- Walls

3-Base
Final Output of B surface-
Creating Class C Surface- Using Sweep command and Class A Surface-
Smoothing the curves 
The final Surface output which will be getting solid using the close surface command in part workbench-
Draft Analysis on the solid part-
