Where is vertical product API documentation?

[sinc]

Where can I find the API documentation for LDD and Civil Design objects (2004 versions)? I'm trying to write something that needs to access point, alignment, and profile data, but the online ActiveX and VBA Documentation seems to only include the base product's objects.

Hello,
I don't have the civil product but would guess that they are in
CHM files in the help directory under the directory where
Autocad resides. That's where the ADT customization stuff is.

Thanks. Apparently what I neede is there in the aec-autoreference.chm and land-autoreference.chm files, so I can get to the help I need by typing

(help "land-autoreference")

For some strange reason this help isn't accessable from the default menus, although it's easy enough to add a menu item that can run the above command. It seems strange that the help would be "hidden" in this way, but whatever. I know how to get to it now.

This hidden help resource also told me how to get the objects I need into the VBAIDE object browser by enabling AEC and Land types in Tools->References. Thanks for the pointer. I should be set to start coding now.

You're welcome.
Its inconvenient to get to the ADT automation help files also. They
are relatively well written though. Good luck.
