A consistent vectorial draft from the THIEME Scientific Atlas, with two an­gles rotation of the right leg was also scaled ans superimposed [red].
This upholds how the mo­ve­ment centered on each ball-and-socket joint between the head of the femur and the acetabulum describes circles that announce different lenghts of the legs, such as they are designed.
I had just to ro­tate the right ver­ti­cal leg to the ex­ter­nal po­si­tion, su­per­im­pos­ing the knee (50%), to note that the lenght of the shin is short­er [dark to yel­low arc] than de­pict­ed there [yel­low leg; or that the sup­port­ing plane of ro­ta­tion [lower red arc], being exterior to the cir­cum­fer­ence from the same side of the leg, nev­er me­ets it with­in the an­gle that the leg can normally reach.
