Week 9 - Attachment Feature Creation - Challenge 2
Door trim with dog house

Tooling axis

extract a suitable surface from the class a surface
mark a point on the surface and create a plane (x-y) on that point

intersect the plane and the class a surface then mark two line and bisect it through the above mentioned point
make a y-z plane on that point and intersect it with the a surface

then create a line like this through the point

then bisect those two line through the point to obtain tooling axis

create a line in the direction of x axis with respect to tooling axis to obtain side core axis
Draft analysis

the angle the surface have with respect to tooling axis is shown as above
dog house draft analysis

angle the dodhouse have with the side core axis is shown above
