Im aware of the difference. Whe I refer to "the same tag" is the same
tagname from the same tagset. This, according to the MicroStation
manual, is invalid, but only for interactive purposes. After my mail I
wrote a program that ataches two instances of the same tag to one
element and the result is alright from the dgn structure point of view.
Interactively I get only one tag and tag reports give a "tag-mix", but
programatically I can manage all the tags perfectly with the mdl
functions provided (That is what I want). The problem is: Is it safe to
work according to dgns structure or we have to addopt the limitation of
the interactive tool?
Maybe you are asking yourself: "Why this guy needs to do so?", well I
have elements that refer to one plant item but others refer to multiple
plant items and the simpler, more natural and more flexible way I find
to do this is using several instances of the same tag attached to the
Thank you for your answer Ill keep searching.
