To begin, an extrude forms the main cylinder of the part. A new plane is constructed tangent to the top of the cylinder and parallel to the top plane to be used to build the hook anchor portion of the part. The hook anchor portion of the part is modeled as a large mass. Additional cut operations will remove material to achieve the correct design intent. The cut “Shape Bottom” creates a hard edge where the drafted cut intersects the corner radius. The face fillet tool rounds the edge and has the correct draft angle. Split lines will be used to add new edges to the model representing the parting line. Delete Face is used to remove unwanted faces from the model, including the fillet stop block. A variable fillet is used to model a fillet that terminates as it hits the parting line.
