To start our final project, we were assigned to create joints that we would be able to use in our final action figures. I made 2 types, one that is like a hinge and a ball and socket joint.
First i created this sketch using a rectangle and mirrored lines.
I next rotated the inner trapezoidal shape to form the first body.
I then rotated the outer pieces as a single body.
Next i moved the outer pieces closed to the middle piece.
I then sketched on the perpendicular to create a solid foundation
I next extruded the rectangles in both directions
I then sketched a large rectangle over the entire object
Finally i connected the two sides so that the middle piece could rotate freely
For the ball and socket joint, i created a sketch using circles, rectangles and lines.
Next I rotated the object to make a cup-like body
I then used an offset pane to sketch a cross
The cross was used to cut out sections so the two end pieces could stick together without breaking
The inner piece was then formed using a circle and a rectangle.
The inner piece was then rotated
The final pieces
The ball socket needs adjustments to fit the size of an action figure, but this is a start.
