AutoCAD to a Second Life surface

[dboheman]

This is my first post to any forum of any kind. Please be patient with me.

 

I'm a design engineer in the US who logs onto SL (Second Life). I created a stormwater facility there by laboring through the terraforming tools available on that site. I'm looking for a way to create a surface in AutoCAD Civil 3D and upload it into SL. A web site I visited said to use programs named Terragen and Bailiwick to move a surface (grayscale to heightmap) as a .RAW file to SL. I have a copy of both programs including Bryce 7.1. CADTutor provided a method of moving AutoCAD meshes to Bryce; however, a program named Key Terra-Firma was mentioned as a way to achieve this. I guess I have 2 questions. One is Am I going about this the right way? The other is How do I acquire a copy of Key Terra-Firma and the price of it?

The simplest conversion most software supports is 3d faces , Civil 3D Surfaces, Utilities, Export objects from surfaces you must have mesh displayed for it to work select in tick box.
