Week 9 - Attachment Feature Creation - Challenge 2
DOG HOUSE is a feature which helps us to prevent sink mark ,there are mainly 3 reason for Dog house,
1.Avoid sink mark
2.Solve the length issue
3.when we have a perpendicular screw bosses from B surface
TOOLING AXIS - To create tooling axis we have to confirm the best suitable direction by using compass .the y direction is suitable for part ,becuase in this direction maximum number of parts are visible ,and create a line normal to plne
SIDE CORE TOOLING AXIS - In sda after creating dog house to give draft angle inner wall we construct it as refernce by main tooling axis in zx direction ,
DRAFT ANALYSIS- In draft analysis after tooling axis we confirm that the draft angle is suitable for part thta can easily remove from mould here some drafted part A,Doghouse
surface b ,
for complete body with dog house , 
Surface A
Surface A -it is given by engineers to work on it
Surface B - It is a engineering surface where we can attach dog house,rib or any engineering construction to get desired result.
Final surface -In this we use A+C surface to merge with b, c surface is used to join A and B it means it is a thickness of part
DOG HOUSE - In dog house we first take a plane on surface and then we construct a sketch ,to perform following operation some tools are used like
extrude,
surface thickness
boolean operation
split
trim
offset
traslate
TREES STRUCTURE FOR OPERATION'
