In answer to the issue of not being able to save the session when the free manikin has been loaded
PTC is using/proposing a product called: DRM ( Data Right Management). This allows PTC users to protect their geometry. The Manikin product is using this protection. This tool is really efficient to protect your product. it would block all saving activities even if you remove the protected object from your session. After the first implementaiton we realized that it was too restrictive for the manikin and mainly for the manikin light. Therefore we removed to some extent the DRM session saving restriction.
Starting in WF4 M0100 the user will be able to laod the manikin light and manipulate it. The manikin can still no be saved without the license but after removing the manikin from the session. the user will be able to save his session.
