I would like if Inventor could store Page Frames and Title Blocks in an external library as it does for symbols since 2016 release.
With the normal Zone Border command, inventor cannot fulfill requirements of ISO 5457 (attached). Therefore the only workaround at the moment is to design static frames and replace them by page size change. Unfortunately ISO 5457 conform page frames A4 to A0 will make your IDW template about 0,5 MB big, and this will be replicated by each newly generated IDW in your company, without any real need for it.
The full solution of this problem also requires some additional VB development to replace the frame when the page size is changed, but storing company frames in an external library (as it happens for symbols since release 2016) would for sure help most of users keeping their IDWs more clean, better organized and easier to maintain.
And if doing it for PageFrames, why not to do it for TitleBlocks as well?
So if you like the idea, just vote it
