SplineLand is a plugin for Autodesk 3ds Max that helps to generate topographically accurate terrains from a set of splines and lay roads.
Without SplineLand it is almost impossible to achieve such accurate results in 3ds Max. Now you can do it quickly, in just a few clicks your topographical data in form of splines can become a terrain.
