anthropomorphic robot workspace

[brn]

I would like to draw a part containing the work space of an anthropomorphic robot, and then bind it into the robot's axieme and be able to activate it as a configuration to visually evaluate the maximum positions reached by the robot.
However it is certainly not a revolution, I tried with half revolutions and loft but I did not come to the head. Does anyone have any ideas?
Thank you all.

ps to clarify the sketch of the imported robot in the sketch of the attached part is freely made available to the manufacturer

Why do you say it's not a revolution? ? ?

It is a revolution, but certainly not 360° could be 2 revolutions at 180° or is something missing from me?

How is a robot axis 1 made? I guess. commanded by his good driver. Right?
