Topic: Does anyone know where to find Grading Groups in the Civil3D API??

[stevenh0616]

Hi,

I've been looking through the API for Civil3D trying to access Grading Groups. It seems like there would be a method under Sites to access Grading Groups IDs, but there is nothing there that I have seen. Been looking elsewhere like the CivilDoc as well, but can't seem to find them.

Does anyone know where they would be? Thanks in advance.

The Grading & Grading Group objects have not been exposed by either of the C3D API's. My guess is that since these are still quite unstable without us messing with them, they don't think we should be trying to manipulate them. If you want to see these in the API, I suggest making sure to give your input in the API Wish List Survey which will be closing June 11.

Using a bit of lisp to quickly check what a grading object is, shows us that these are special Parcels. But listing the Parcels in a Site does not include the Grading Parcels.

Ahhh... not what I wanted to hear. And all I wanted to access was the name and description.

Bummer. Definitely will go and vote, but I agree they are unstable. We've had some strange things happen with them.

Thanks.
