Comments
To avoid the graphic being visible during MotionSolve result animation in HyperView, set the hide_in_post attribute to {{true}}. For example: *Set(gra_link.hide_in_post, true). This option will set the graphic component's visibility to be turned off when the result H3D is loaded in HyperView.
