AEC vs AECC

[ilia.borisov]

Can someone explain what is the difference between AEC and AECC object and what they are actually.

[Jeff_M]

AEC= Architectural base objects
AECC = Civil base objects, many of which derive from AEC objects.

[ilia.borisov]

Ok but which are aec and which aecc?

I would think that if you opened up a civil drawing with vanilla AutoCad you could tell quite quickly.  Just select a few objects and note what Properties Dialog box "says".

I just to read something more in detail about this objects not only what autocad return in answer

They are all custom objects created by Autodesk for those respective disciplines. Here's a link to the latest (C3D 2012) COM API which includes most AECC objects (some have been added after C3D 2012):

As for the AEC objects, you'd have to look at the Architectural API.
