Tooling Axis
for this component, I perform a bisecting method to find the correct tooling axis. I extract a surface from class a and create a point on it. then I introduced a local axis system, with the help of this axis system I use the intersection surface command and intersect in the ZY plan.
then I create two lines on the surface intersection line by point-to-point line creation. after that, I create a line that is bisecting both lines.
A similar procedure was performed in the XY direction
after this process I end up having two lines. so to get the main tooling axis I perform another bisecting line procedure.
Finally, I got the main tooling axis for the Dog house

Draft analysis
Draft analysis is a common tool used in CAD (computer-aided design) software to determine the angles of sloped surfaces in a 3D model. The purpose of the draft analysis is to identify surfaces that do not have a uniform angle of inclination or draft angle, which can cause manufacturing and production issues in processes like injection molding, casting, or stamping.

some areas are not clear with the draft direction (need to modification in Class A surface)


Class B surface creation
offset 2.5mm

2 fillets are not come properly

for that, I extracted these areas and then extrapolate and later trim them together.

Class C surface:
for the Class C surface, I created a boundary using the help of the class A surface. later I sweep with the reference class A surface at 87 deg outwards.
problem: with this operation, a sweep will not be created as we desire. there is some area it needed troubleshooting.

that area I remove (join command - sub-element to remove) and profile sweep with the boundary. later i joined the ends by multisection operation.

After the Profile sweep it's not joining with other end of the C surface so remove the white Circled area (join-remove sub-elements). than performed multisection.

multisection

there are other areas that also have the same issue. i performed this process there as well and finally, create a complete C Surface
