Week 8 - Challenge 2 - Switch Bezel Design

OBJECTIVE

To Design and Develop Class B and C Surfaces from the given Class A surface
With Create Prossible Tooling Axis
To Analyse the solid component (Combine Class A,B and C) in Featured Draft analysis with Guiding Reference of Tooling Axis.

Class A Surface

Tooling Axis

From the Given Class A surface, to determine the possible direction of component to draft
Extract Base of the surface (No propagation)
Point is created on the base of the surface
then add Axis System on the ref.point
Along this axis system YZ direction Positioned sketch as to construct
Intersection of the surface along YZ direction,inclined Edges of intersection sketch two Lines
from these two lines create a Bisecting Lines of YZ Direction

Screenshot of YZ Bisecting Line

To create XZ direction Bisecting Axis of the surface, by positioned sketch
Compare to YZ Direction, XZ direction have a one side of face to intersect
By intersection on XZ Direction, One side of Inclined edges create line and
then create line on the axis system projection point (Ref.Point) and constraint to the angle of 3 degree from the Intersection line.
And the line as considered Bisecting Line of XZ.

Screenshot of XZ Bisecting Line

Both YZ and XZ Bisecting Lines, Create Bisecting Line as Tooling Axis of the component to develop Class B and Class C.
then also Featured Draft Analysis as to derive along this Tooling Axis.

Class B surface construction

Side Walls

Extracts side Walls of the Class A Surface (No Propagation).
Then Untrim those walls and extrapolate in point continuity (Propagation) with distance of 50mm.
Trim all the Walls and Offset through outward of 2.5 mm (Because of thickness of the component is mentioned 2.5mm).

Base

Arm Rest

Screenshot of Arm rest Surface

Trim all Side walls, Base and Arm rest surface and Edge Fillets are created
On Filleting the Class B surfaces, to considered the Thickness of the component 2.5mm
For Inward Fillet,Radius of the curve is 14mm minus the Distance of Class A to Class B 2.5mm and Resultant fillet radius is 11.5mm
For Outward Fillet, Radius of the curve is 15mm Add the Distance of Class A to Class B 2.5mm and Resultant fillet radius is 17.5mm

Class C Construction

From the Class A surface, Create Boundary of the surface
Then Using Sweep command, Create Class C surface at 3 degree of Draft angle and distance of 20mm in the Tooling axis Direction.
