Week 9 - Attachment Feature Creation - Challenge 2

CLASS A ANALYSIS

PROCEDURE:

Check for any openings in the given Center Console Coin Holder model by using BOUNDARY. In BOUNDARY > select edges - select the surface to create the boundary at the openings.

BISECTING METHOD:

CREATING TOOLING AXIS:

Create a point at the center of the base by using Point Definition by extracting the surface and selecting the surface Create an Axis system at the point that is created at the surface using Axis System Definition by selecting the point.Now create an intersection in the ZY plane by Intersection Definition for the Center Console Coin Holde Now using Point-Point in Point Definition extend the line to take reference drafted lines on both sides and bisect those lines to get the direction in the ZY plane.Create an intersection in the ZX plane and create a Tooling axis in the ZX plane.Bisect those two tooling axis lines, create a Main Tooling axis(Blue) , name the bisected line as Main Tooling Axis, and do the draft analysis for the Class A surface.

CREATING B SURFACE:

Now create the Plastic design for the given Class A surface of the Center Console Coin Holder by creating the Class B and C surfaces Create a Geometrical set in a tree and name it.Extract the side wall surface of the Center Console Coin Holder by Extract option by selecting the face.Select the faces Untrim the extracted surface using the Untrim option by selecting the surfaces. Extrapolate the Untrimmed surfaces using the Extrapolate option.In Extrapolate Definition: Boundaries - select the edge of the Untrim surface and Extrapolate - untrimmed surface and offset the surfaces to 2.5mm in the opposite direction to the Class A surface Extract the base surface and block and do the same process and offset the surface to a distance of 2.5mm in downward direction Trim the Excess portion of the surfaces using the trim option Do the same process for inclined walls surface and outside wall surface by extracting and offsetting the surface and trim the component Add the fillets at the wall's edges.

CREATING C SURFACE:

Create the class C surface for class A surface by using the Multi extract option by selecting the boundaries.Create a smooth curve for the extracted boundary.Select the extracted boundary Extract the outer boundary walls and Replace the Multi extract boundary with the Smooth curve Now using the Sweep option create the C surface by selecting the Subtype as - with reference surface and Guide curve as - Boundary which is extracted and Reference surface as - Extracted boundary surface and Angle of 90 - 93 degrees to maintain Draft Angle.Join the surfaces and trim the surfaces with Class B and Class C Check for any open boundaries in Plastic design and create the solid surface for the design in Part design using a closed surface option Now do the draft analysis for the solid component tooling axis and check for the draft angle as it should be in green in colour in the tooling axis.

CREATING DOG HOUSE:

Create a sketch on the extracted base surface where the the dimensions should be more than the screw boss As for the Dog house one of the sides should be opened,make one side as a construction line Extrude the sketch by using the Sweep option with the 1.5 degrees to the height of 20mm towards top and 1mm towards bottom Cut the uneven surface at the open side by extracting the opposite surface and offset it to a distance towards the open surface and split the part in Part design by using the Split option.Draft the inner walls with 0.5 degrees.Now create backside contact surface by offsetting the extracted base surface to a distance in between 3 - 6mm height (B) and Sweeped surface to a distance of 40% of the main wall thickness(C).Trim the surface.
