I have been working on developing some workflows using the same AutoCAD building layout and then placing it as an XRef into different AutoCAD sublayouts. These workflows work great for the FDS Standard version, but I have discovered a problem when syncing to Inventor. For some reason it won't let me sync from Inventor to AutoCAD because it wants to overwrite the XRef files. It would be much easier to simply see any XRef files as references also in Inventor and not attempt to overwrite them during the Sync process. That way a master layout overlay could be used multiple times in a large comprehensive design. If you have any questions, please do not hesitate to contact me. Hope all is well and have a most blessed day!
Peace,
Pete
