Week 8 - Challenge 2 - Switch Bezel Design
AIM: To Create the Switch Bezel Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.
CLASS A SURFACE
CONSTRUCTION OF TOOLING AXIS
Intersection of class A surface.
Bisecting lines are drawn for the construction of Tooling Axis.
Tooling axis creation
DRAFT ANALYSIS OF CLASS A SURFACE
B SURFACE CREATION
- Extraction of class A surfaces.
- Untrim the surfaces.
- Extrapolate the surface in point continuity and check all the surfaces are intersecting each other.
- Then trim and offset them to 2.5 mm towards outer direction.
- And the class B surface is ready.
CLASS C SURFACE CREATION
- With the Multiextract command select the boundary of the class A surface and sweep with the draft angle of 3 degree.
- Extrapolate the end and trim them to make the final C surface.

DRAFT ANALYSIS OF FINAL SURFACE BODY
PROCEDURE
- First the class – A surface is checked before creating the Class –B&C surface and finally the solid body must be analysed. Both can be done by following the below procedures.
- By changing the view mode to custom view parameters – Material mode then the feature draft analysis is enabled.
- Then the compass activated and placed on the tooling axis by dragging the pointer and then locked it.
- Then, by selecting the quick analysis mode, the nominal draft value will be 3 degrees and checked for the component's draft angle.
- The green colour area shows that it satisfies the 3-degree draft angle. If not satisfied then by using the Running point tool the area is measured and then altered to get a successful draft for the created tooling direction.
- In plastic design we can keep our draft angle value from 0.5 to 3 degree.
- here I got complete green in 0.5 degree analysis.
