Week 9 - Attachment Feature Creation - Challenge 2
AIM:- To create the Dog House for the Door Trim with given Class A surface.
OBJECTIVE :-
Created a 2.5mm solid part body of door trim with the help of class A surface, and created a B-side attachment feature 'Dog House' by considering the design parameters.
TOOLING AXIS :-
For tooling axis we have created a point on the surface and created a line perpendicular to that point.
CLASS A SURFACE :-
CLASS B SURFACE :-
We have offseted our class A surface 2.5mm then we found some patches in class B surface which we have to fill.
so for the first patch we have extracted the surfaces and the extrapolate then trim and given fillet, hence we have our final patch filled.
and then for the second patch we have just use multisection to fill this and just simply join this with previous part.
CLASS C SURFACE :-
For the class C surface we have used sweep method to generate the areas.
CLASS A+C SURFACE :-
After complete formation of class C surface we have joined with the class A surface.
OPEN BODY :-
We have our open body by trimming the class C surface and class B surface.
CLOSE BODY :-
we have used the close surface (part design) for thicken the body.
DRAFT ANALYSIS :-
Draft analysis is required to check if a part has required draft or not.The Draft analysis refers to a Tool that allows us to determine if we can remove the part we designing from the Tool being used to design it.
DOG HOUSE:- Dog HOuse is an engineering feature used in plastic trim design.Dog houses are used as supporting feature. The primary function of Dog House is to avoid SINKMARK.
- For designing Dog House, firstly we have created a sketch for that.
- Then by using sweep method we have taken angle of 1.5 degree in inside direction.
- I thicken the surface outward direction by 2mm.
- After that we have given the fillets and take all the areas as per design rule.
For the lower cut we have extracted the surface and trimmed it with the solid body with the draft angle.
Our final DOG HOUSE
DRAFT ANALYSIS :-
Side core Axis
In the color bar, I gave 0.45 deg for green because the sweep angle is 0.5 deg for the outer surface.

TREE STRUCTURE :-
CONCLUSION :-
WE HAVE CREATED DOG HOUSE WITH GIVEN CLASS A SURFACE AS PER DESIGN RULES.
