Creating a ground surface

The Ground tools, located in the Common Tools group on the Home page, provides options to import 3D ground data from various file formats.

Model_Ribbon_Home_Common_Ground

Selecting the Ground menu opens a drop-down menu with four options to generate a ground surface.

Model_Ribbon_Home_Common_Ground_Expanded

hs-caution

Ensure that data in the file to be imported is in the same coordinate system as data in the model.  
If not, the model may become unresponsive / fail if the extent of the model is too large.

•Ground From LAS - creates a Ground surface from a LiDAR (*.las) file.  

•Ground from ASC - creates a Ground surface from a ESRI ASCII GRID (*.asc) file.

•Ground from TIN - creates a Ground surface from a ASCII TIN (*.tin) file.

•Ground from CAD - creates a Ground surface from a CAD (*.dwg/*dxf) file.

Once data from the file is read, this data is automatically converted into a triangulated surface that is added to the Ground layer.
