Week 10 - Challenge 2- Attachment Feature Creation (Dog House)
DOG HOUSE CREATION:
AIM:
- To Create dog house for door handle from given class A surface.
- Create solid body from final trim,and create dog house as per industrial standard dimension.
GIVEN INPUT:
CREATION OF TOOLING AXIS:
- First we need to create tooling axis,for that we need to create axis on center of the gravity of the part,then using line command click that point and z axis.
- Then using draft analysis and we finalyze the tooling axis.
DRAFT ANALYSIS OF CLASS A SURFACE:
- In draft analysis we need to give 3 deg with repect to the tooling axis.
- By color segments we are easily find out our tooling axis.
CREATION OF CLASS B SURFACE:
- For creating B surface we need to offset the Class A surface about 2.5mm as per given data.
- After offseting we got improper non conecting surface by bounadary,multiple extract,extrapolate and trim we create our class B surface.
CREATION OF C SURFACE:
For creation of C surface we use sweep command with respect to the tooling axis.
CREATION CLASS A & C SURFACE:
By using extrapolate,join and trimming we are create the class A&C join.
FINAL TRIM:
We need to trim Class A&C join and class B surface, For that we need to extrapolate the B surface and do the self intersection analysis.
CLOSED SURFACE:
By change the surface design to part design and create solid body using closed surface.
DOG HOUSE CREATION:
- First we need to decide the position of the dog house.
- Then we need to sketch the dog house overall dimension like length,width,angle and x,y coordinates.
Sketches:
- Create a sketch with ISO constrain to create the dog house.
Extrude surface:
THICKENING OF SURFACE:
SPLIT:

DRAFT ANALYSIS AFTER CLOSED SURFACE:
CONCLUSION:
From this challenge we are learned how to create Dog house attachment in plastic part and creation of closed surface from class A surface as per industrial standards.
