Landscaping add-on for ARCHICAD®. Introducing LAND4 Composites making it possible to link information about Building Materials to terrain surfaces.

Fast, flexible and precise terrain modelling.
LAND4 offers enhanced, direct and accurate control of your terrain model in ARCHICAD and saves you a lot of time.

With powerful tools like easy import, dynamic Spot Levels, Fall Lines, Contour Lines, and LANDSurfaces (the LAND4 terrain model), combined with a new Category functionality, LAND4 will help you optimise your workflow right from the import of surveyor data and all the way through to your final project presentation.

Easy Spot Level configuration
- Basic, automated Spot Level configuration.
- Dynamic, interdependent Spot Levels.
- Fall Lines.
- Interpolation between two Spot Levels.
- Interpolation between three Spot Levels.
- Gradient interpolation.
- Constant gradient interpolation.
- Point Slope to terrain model (LANDSurface).

Dynamic LANDSurfaces
- Create dynamic terrain surface models (LANDSurfaces) from Spot Levels.
- Control the terrain surface with Ridge Lines (break lines).
- Create organically shaped holes using the ARCHICAD Fill Tool.
- Show Contour Lines with height distances of your choice.
- Turn a LANDSurface into an ARCHICAD Mesh and vice versa with just a couple of clics.

Simple and safe import and export of data (XYZ)
- Import XYZ data from CSV, TXT or XYZ files directly into LAND4.
- Turn imported XYZ data into dynamic LAND4 Spot Levels in seconds.
- Export your own LAND4 XYZ data to CSV in a few clicks.
