Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

AIM

"C" is where the doghouse contacts the backside of the surface

DESIGN RULES GIVEN

• Doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ).

• The height of ( B ) should be between 3.0 – 6.0 mm

PROCEDURE

Create B Surface for given A surface

Offset the A surface and Extract surface and extrapolate the surface

And Trim the surface.After edge fillet to be followed

Create C surface by using A SURFACE

Create Boundary and sweep the boundary with Reference of class A surface

Join the CLASS A & CLASS C SURFACE

Finally Trim the CLASS B & CLASS A&C JOIN

Create Ribs and screw boss

create a sketch and extrude the sketch and thickening the surface

And Union Trim the Main body

create Sketch and draw circle and pad that inner and outer circle

Extrude the circle and ASSEMBLE MAIN BODY

Before that need to give draft for all body

Finally Edge fillet to be use in sharp corners

Draft Analysis to be followed in CLASS A , FINAL OUTPUT
