API Cable from-to

[roberto.scroccaro]

Hi,
I'm trying to get info about cable's connections between wires (lines) and bloks.
I've found a report 'Cable From-To' (WD_CABLE_RPT) that gives me all these info but I
would like to get them via API (I don't need a report file).
I'm able, using .NET and c#, to loop through the BlockTable, LayerTable, entities, attributes and so on
but I cannot find the appropriate object/api that contains these information.

PS: another way could be, if possibile, read directly to the database table "WFRM2ALL" and "WNETLST" 

Could you please help me?
Thanks in advance, bye.

Hi Roberto.

I saw you raised this question at Autodesk support also, so I'll put my answer here also, for future reference:
"As you've found out, there's no way to get connection information directly using the API.

Unfortunately, the connection information in the project database is also poorly documented, as you're not supposed to do much there manually.

However, Nat Holt (the father of AutoCAD Electrical) has documented the wire data for us, in this blog post:

So, you CAN manually parse this information and recreate the connection information from this, but depending on what you create, going through a report might be quicker."
