Download Lands Design
Lands Design works as a plugin for Rhino. If you don’t have Rhino, you can download the Complete Package which includes an evaluation version of Rhino.
You can get better results by using Lands Design and Flamingo nXt together. If you already have Rhino but you don’t have Flamingo nXt, you can download the Render Package which includes the Flamingo nXt Evaluation version.
