thanks for your attention to my query.
looking at the Spotlight Workspace, selecting any icon in the Spotlight Palette (tools) window does not activate the tool. Instead, a window opens stating: ?The plug-in tool ?X? could not be selected. Check to make sure it is in your ?Plug-ins? folder.?
Such is the case for any Spotlight tool selected.
Within my drawing (dwg) I can select and move any fixture, but I can not place anything new.
Four examples are: ?Light Position Obj.vso?, ?Curtain Object.vso?, ?Accessory Insertion Tool.vst? and ?Inst Insertion Tool.vst?.
The plug-ins are located inside the plug-ins folder; I can see them, why can?t Vectorworks 12.5.0?
i am working on a borrowed computer and do not know the history of the VW installation. could it's provenance be an issue? except for this stumbling block, all seems well.
