Has anyone written a CAD standards plug-in? I can find no documentation on how to do this. The 'IAcStPlugin' interface declared by the 'Autodesk Standards Manager Type Library' (AcStMgr.dll) looks interesting, but I don't know which methods I have to implement in what way. Also, it looks like you only get access to system variables and symbol tables. The block tables (where all entities sit) are empty. Greetings, Ken
