What's the difference between ObjectID and PpObjectId ?

214860559 — Sun, 05 Jul 2020 11:07:07 GMT

I met problems as follows:

1) What's the difference between ObjectID and PpObjectId ?

2) What the rowId get from dlm.FindAcPpRowId(pnpId) stand for? how to understand the rowID?

The SDK has no detailed message of the managed Classes , thus it is hard to understand some member and method， thanks very much for your reading.

ObjectId is the standard unique identifier for all AutoCAD objects - line, circle, block, etc.

PpObjectId is the unique identifier for rows in the Plant 3D database.

2) What the rowId get from dlm.FindAcPpRowId(pnpId) stand for? how to understand the rowID?

Row ID is an integer value which is the same as PpObjectId - see more info here.

Thank you very much for your reply, but i get a little confused after I complied the link program, does it mean the PpObjectId and rowID used only in PID not in the piping part of P3D?

Each PnID object AND each P3D object have a unique rowId/PpObjectId.
