Door Arm Rest Week 8 Challenge

AIM:- Create the Door Armrest 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.

OBJECTIVE:-

• Create Tooling Axis
• Perform a draft analysis on Class-A surface
• Creation of Class-B and Class-C surface
• Creation of the proper tree structure
• Publishing the Tooling Axis and Class A, B, and c surface.

Construction:-

• First, check the connectivity of the Class-A surface by using the boundary condition.

Construction of Tooling axis:-

• First, create a circle and point on the hole for creating the cooling axis.

• Create the Main core tooling axis by selecting the direction as a compass Direction.

• Create the Side core tooling axis by selecting the direction as a compass Direction.

Construction of Class B Surface:-

Bottom half

• First extract and surface untrim the bottom half.

• Extrapolate the surface.

• Offset the surface at a distance of 2.5 mm.

• Finally, trim the to half surface.

Top half

• Do the same for the top half first extract and untrim the surface then offset at a distance of 2.5 mm.

• Finally, trim the top half surface.

Base

• First, extract and untrim the base then offset the surface at a distance of 2.5 mm.

• Then extrapolate the base surface.

• Finally, trim all the surfaces to create the base.

Hole

• Do the same for the hole.

Grove

• Create the sweep by selecting the profile as the line and guide curve as the curve.

• Then Extrat and untrim the surface that is seen at the top in the grove.

• Extrapolate both the surface.

• Finally trim both the surface

• Offset the surface at a distance of 2.5 mm.

Final trim

• Then Trim The bottom half, top half, grove, base, hole.

Finally, give all the fillet value and the Class B surface is created.

Creation of Class C surface:-

• After the creation of the Class B surface, the Class C surface should be created. To create a Class C surface we should use the sweep option.
• Sweep the plane surface by specifying the angle.

• Create the multisection by selecting the section and guide curve.

• Extrapolate and trim, then join the surface together.

• Then, extrapolate the surface.

Final trim:-

• Finally trim the Class A, Class B, and Class C surface.

Trim Class A surface with Class C surface.

Trim Class C surface with Class B surface.

Finally, Create the solid surface of the door arm rest.

Publication of all the surface

DRAFT ANALYSIS:-

• The hole is not clearing so we can create a protrusion that comes out of the side core and create a hole in the door arm rest.

Finally the door arm rest surface and solid are created from the class A surface. The draft analysis of the component is also complete.
