Week 9 - Challenge 2 - Switch Bezel Design

Switch bezel is a car part which contains switches and buttons to control different functions like window control,door lock,media etc. It is located at the inner portion of the door. The procedure used to create the part was same as the base bracket one. Class A surface was used to create the tooling axis. Class B surface was created at a distance equal to the thickness which was the identical surface of class A. Class C was formed as the wall of the model and then all the three surfaces were joined together and draft analysis was carried out.

Draft analysis report for final component :-

Class B surface creation :

• A new geometrical set with the name B surface was made and the top, side and bottom surfaces were extracted.
• The same surfaces were untrimmed and later extrapolated to carry out trim command in between them perfectly.

• After getting the surfaces, it was trimmed and made to form a single surface.

Class C surface creation :

• A new geometrical set with the name C surface was created.
• Multi-extract command the boundary was created on the A and B surface.
• It was made into a surface by using swept option and the tooling axis was considered and also the draft angle=3degrees.
• The surface was having too many marks so smooth curve command selected and replaced by the the above curve to obtain a smooth surface without marks.

• Surface A and C were joined by giving 0.003mm as merging distance.

• The last geometrical set was created and was named Final join. Surface A and C were joined to form a single surface and in the same manner surface B was trimmed taking into consideration the above mentioned surface to get the final part.
• The window was switched to part design where the hollow part was turned into a solid part by using closed surface command.
