Door Arm Rest Week 8 Challenge

Aim : To Create a Class B & classs C surfaces from the given Class A surface of door arm rest & to draft analysis the surface of given model.

Creation of tooling axis :

Tooling for x axis

Tooling for y axis is

Then By using bisection method Bisect the resultant Lines

Now,we got our tooling axis

Draft analysis on class A surface

Creation of Class B surface

• Extract the surfaces from the Class A surface part by part except for the fillet surfaces.
• Untrim the extracted surfaces Extrapolate the surfaces if needed such that the surfaces are intercepting each other,
• Offset the untrimmed surface up to 2.5 m such that maintaining the thickness as mentioned.
• Trim the offset surfaces as per the shape of class A surface.
• Create fillets to the trimmed surfaces as per the measurements of the class A surface.The fillets are created in such a way that the outer fillet radius value is added with the thickness of the component or subtracted of the fillet is in the inner side.
• class B surface process is to be done part by part for simple trimming process.

now this is our B surface.

Creation of Class C surface

After creating the class B surface,class C surface is to be created for the class A. Class C surface is the side surface of the solid component.

Create a boundary line on the edges of the class A surface. Four boundary lines are extracted on four sides of the component.

The extracted boundary lines are sweeped,setting the created boundary lines as guide curves and the tool axis as the draft directions.The angle of sweep is given as 3 degrees so that the components is acceptable for the draft analysis.

After that few regions are created using the blend option as the sweep feature is creating error while creating the surface.

The above dia is our classs c surface

After that we join Classs A & class C surface.

Trim the Class B & C Surfaces & join the trimmed surface with class A surface.click the component such that no surface opening are formed.

After creating a close surface,fill the solid in closed surface component.
