VectorScript plug-ins are created with the VectorScript Plug-in Editor, which can be opened by selecting Tools > Scripts > VectorScript Plug-in Editor. The plug-in editor provides access to all the settings needed to define any type of VectorScript plug-in, and can be used to edit existing plug-ins as well. The editor interface provides a listing of all plug-ins currently available to VectorWorks, as well as tools for managing individual plug-in items.
Once a new plug-in has been created using the Plug-in Editor, it is made available for use in VectorWorks by adding it to one or more workspaces with the Workspace Editor.
See Creating or Editing a Workspace Once the item has been added to a workspace, it is available to any open file in VectorWorks without the need for importing the associated script into the active file.
