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

DOG HOUSE - DOOR TRIM

TOOLING AXIS CREATION

CLASS B SURFACE CREATION

add a new geometrical set for surface
offset the class a surface to 2.5mm
then find out the missing surfaces and remove those adjacent surfaces to make it 3 components
then extract, untrim and extrapolate each part and trim together to make it a whole final surface
when extrapolating do point continuity, and leave a excess surface for final trims
add a new geometrical set for fillets inside b surface
then find out the fillets for each and every connections so made and add those fillets acconding to the offset value
that will be our class b surface and publish those

CLASS C SURFACE CREATION

unhide the class A and take the boundary of the class a with 2 sections
then sweep the boundary to 20mm front and back with draft direction of tooling axis with draft of 3 deg outward
then extrapolate the the 2 ends and trim them to create a class c surface

CLASS A + C SURFACE

THE FINAL TRIM WITH B SURFACE

Trim the last trim with class b surface
becuase we had extrapolated the b surface to about max we can easily trim that with the class and c without any error

FINAL PART

DOG HOUSE CREATION

make a point on the surface
create a axis system on the point
create a line parellel to the point wrt to the axis system
extract the line that will be our base
make a rectangle on another sketch for the frame of the dog house and open one end
then sweep that skectch wrt the tooling axis with 1.5 deg draft
then close the top with offset of the extrude we made first and trim that to make one component
thicken the trimmed surface outside with 2 mm on a new body
make a side core tooling axis with the same point used for main tooling axis but with the direction corresponding to the side core tooling direction
then draft the inner surfaces of the dog house with .5 deg facing face as the neutral element and side core axis as the pulling direction
then add fillets to the inner surface
then extract the inner surface with tangent continuity
and offset the initrial extract to 3-6 mm
and inner surface inward direction of 1mm that is 40% of the total thickness
then trim that two surface and extrapolate them to exceed the part
and split that with the part
then add the draft for the cut portion of .5 mm likewise the other inner draft and add resp fillets
then do the draft analysis that inner surface clears with the side tooling axis
check the orientation of the dog house and rotate that wrt the required position
then make a copy of the body and paste special with attachment as a link then translate that to the required point
trim those two with the main part
