LISP to create Civil 3D surface from Point file

[hakangus]

I want a LISP routine that creates a TIN Surface in Civil 3D from a specific CSV-file. Is that possible?

To clearify my needs with a little more info.

Backkground:
We store our height points in an Oracle database. To search them out we draw a polygon, check it in the database with FDO Connection and use it like a boundary. Then SQL creates a CSV file with points that is renamed and copied to the working folder.
That, we have accomplished in LISP and it is a one-button-click.

Wishlist:
The last thing, that we don´t know how to do, is to create a Surface with a certain CSV file in LISP. If we could do that we´ve made it really easy for our users to do their work.
