  • Re: NORMA for Visual Studio 2022 (and future versions)

The project resolved about 80 issues which included upgrading NORMA to VS2017 and then to VS2019.

  • Re: ORM Solutions' ORM Viewer

    Hmm, an interesting approach. The purpose of .orm files is to help people to store and to re-use editable information models.  So I'm curious to understand the problem that can be solved with un-editable .jpeg files? It seems to me that generating .jpeg files from orm files removes 99% of their usefulness and value (if not ...

     Hi Jerry, I tested the link and yes, the link is broken. (I  have emailed Terry about this.) In the meantime, have you encountered a problem in re-creating the model yourself? Ken
