Hi, Yes you are correct, there should be a way to do it and there isn't. ORM's Rmap algorithm stipulates that in relational-mapping a 1:1 fact type like yours with mandatory constraints either on both roles or on neither roles (as in your case), the user needs a way to input his / her preference as to which table that 1:1 should be ...

Dear all, Please note the inclusion of the recently posted macro -- which updates ORM2_Draw2 object-type and fact-type shapes -- in the latest version, 21, now up. Thanks, Andy  

Roger, Unlike the template I sent previously, the attached places the predicate text exactly where it was before the fact-type update. However, it does not try to shift the text to compensate for the re-location of an up-arrow to the right-end of the text (from the left-end, where it sits in pre-v8 fact-type shapes). Cheers, Andy

Hi Roger, You have brought to light a significant issue: In general, the macros that have been added to ORM2_Draw2 depend, for their functioning, on having the (macro's) current version of the object-type / fact-type shapes to work on.      That being the issue, it really is useless to try to bring the new ...

Roger, Yes, the same question had occurred to me, and I did include some thoughts about this in the v20 readme file. But let me summarize and somewhat amplify - and add a new thought, at the end:     It's much easier, for most people anyway, to move your diagram to where the macros are, than move the macros to where your ...

Hi Roger, Well, "fate", which smiled upon you, has indeed played some funny games with version 18: I just discovered that the final version of the unary f.t. shape did not find its way into version 18, somehow. This has now precipitated version 20. Cheers, Andy

Hi Roger, If you were the first to download version 18, would you please re-download? Since that download, I found and fixed a bug in the code that re-glues connections made to the (nested) entity types. My apologies for this, I thought it would be better to go ahead and fix this and re-upload as version 18, rather than make a new ...

Dear all, Please note that version 18 of ORM2_Draw2 is up and available: http://www.ormfoundation.org/files/folders/visio_stencils/entry2862.aspx Cheers, Andy

Hi Roger, Thanks -- as usual -- for your thoughtful, helpful comments. I've now added one more thing, the lack of which hopefully you didn't notice: role-level arity-change in (also) the "adjustable" fact-type shapes (complementing, not replacing, their fact-type-level menu). This addition makes the ...

Hi Roger,  The attached "test drive" is pursuant to the hypothetical requirements I listed in the last message. Please see how well you think this fills the bill, and let me know if you find any bugs.    However, I do hope you're using a version later than Visio 2002: a bug in that version prevents the ...
