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

AIM

To create door Trim and dog house and add thickness to it and generate the Draft Analysis on a solid surface final component.

DOG HOUSE

Dog house is an engineering feature used in plastic design. Dog houses are used as support feature. sometimes other engineering features like snaps, locators and screw bosses are mounted on them to increase their strength.

Dog houses are subjected to draft analysis to prevent breakage of the component during ejection from the mould cavity. Dog house and other engineering components are built on the B-surface.

CLASS A SURFACE

CLASS B SURFACE

2.5mm offsetted from B surface

CLASS C SURFACE

For creating this surface we have extracted the boundary of class A using multi-extract and then converted to smooth curve. now this smooth curve is swept along 90deg with a 3deg draft.
