for what i understand my cycles settings should be at the bottom of objects menu , but it´s no where to wound, i have cycles set as renderer, what could be the cause of this . I have looked it ewerywhere but don´t findt it
As @Mr Zak suggests in the comments, the
Cycles Settings panel does not show in the object properties menu if the active object is a Camera, Empty Object, Lattice or Forcefield; regardless of how many objects you have selected.
Although it is not 100% clear from your screenshot which object is the active object, it appears that you have several
Empty's in your scene which may be the culprit, if not the camera.
