Door Arm Rest Week 8 Challenge

AIM: To create Class B surface and Class C surface from a given Class-A surface of door rest arm and do a Draft analysis of the given model.

SOFTWARE: CATIA v5

COMMANDS:

• Menu> Shape> Generative shape design.
• Class A surface> Door arm rest.
• Class B surface> Construction> Tooling axis> Part A> Part B> Connecter> Bezel.
• Class C surface> Sweep> Split> Boundary> Trim> Join.
• Final trim> Closed surface.
• Publication> Tooling direction> Part A> Part B> Connecter> Bezel> Final trim.

PROCEDURE:

• Create> Points> Mid point> Lines> Bisection> Tooling axis.

• Part A> with Tooling axis> Extract> Surface untrim> Extrapolate> Trim> Edgefillet> 19.5> Offset 2.5> Revers Direction> Ok.

• Part B surface> Extract> Surface untrim> Extrapolate> Trim> Edge fillet> 29.5> Offset> 2.5> Revers Direction> Ok.

• Connecter> Point> Axis system> Sketch> Line 30degree> Muilt extract> Curve smooth> Sweep> 3degree angle> Off set> Ok.
• Extract> selected Surface> Surface untrim> Extrapolate> Ok.
• Spilt> with Lines> has Blend required> Blend> Join> Ok.

• Part A and Part B surface> Trim> Connecter> check no gaps between surface's> Edge fillets> 2.5`+-`5> Ok.

• Bezel> Extract> Surface untrim> Extrapolate> Off set> 2.5> Edgefillet> has required Measurements > Trim> required Surface> Ok.
• Trim> Connecter> Ok.

• Create class C surface> class A surface> Boundary/Multi Extract> Curve smooth> Sweep> with Tooling axis> Split with lines and points> Multi sections surface> Join> Sweep> Surface A> Ok.

• class A surface> Join> class C surface> Ok.

• Final trim> class A&C surface> Trim> class B class.

• Draft analysis> 3degree> Fix Compass> Tooling axis> Ok.

RESULT: Therefore, the tooling axis, class A, B&C are created and also, Draft analysis is performed with an angle 3degrees...
