Andrew,

The URL given I knew about already.
But YES - It is because of this added V18 functionality that I am posting the thread.
I would like to see the block diagramming to be extended on.
It would be great if the blocks can be referenced in a bill of material table.

The ideal is to think of these 2D blocks as if parts in the 3D enviroment.
These 2D blocks is then used on multiple 2D sheets (like Excel sheets) as if a 3D assembly.
Each of the 2D blocks have their own parameters (example 0.55kW vs. 1.1kW motor) just like family of parts.
Some links between connections/sheets may exist that give this 2D sketches added "dimension".
Each wire used should have its own unique number too - so it is a "part" too.
Now if each wire is auto numbered according to ISO standards - GREAT.

Maybe someone already has an add-on program that is at least capable of counting each of the block types used in one project (many 2D sheets).
That should be easy for some to develop?!

Maybe someone already has developed some library blocks one could use.
For example a Siemens S7-300 CPU 313C connection.
Anyone ready to share libraries / knowledge / comments?

WB :-o
