API: getting 3d entities info from their Drawing counterpart

I have been asked to write an add-in that does this:
loop through the entities of a drawing view and for each of them get
the associated 3d entity (typically an edge)

I have no Solidworks API skills.
Looking at the documentation and the available examples I have inferred
that I can easily access entities in a drawing view calling
IGetPolylines5.
The problem is that I could not find how to associate each of these
lines, arcs, etc. to their corresponding 3d edges (or even to the
related features)

This info seems to be available for driven dimensions
(Annotation::GetAttachedEntities2) while this apparently does not work
for driving dimensions as they don't return any associated entity.

Could someone please help me ?

Thanks in advance

 

I have this to say: good luck!

I looked at doing this a few years ago, so I don't know if there have
been any improvements in the API to help with this. What I found is
that there is really no easy and straightforward way to do this. The
best solution that I could come up with was to get the sketch entities
and the 3d model edge entities and then use the model to drawing
transform to mathematically compute which edge matched up to which
sketch entity. Not too fun. In the end I never implemented this
because we decided that it was not worth it.

If you come up with anything better, let me know.

Before we focus on the solution, can I ask what you are looking to
achieve with this add-in?
