LandXML/DEM Model Import
lets you import land development data into 3ds Max Design. Civil engineering
data, from XML, DEM (digital elevation model), or DDF files, is
used to create a 3ds Max Design model.
Import dialog allows for interoperability
with Autodesk products such as Land Development Desktop 3, Land Development
Desktop 2005, Civil 3D™, and CAiCE Visual PE. Once imported, the
models are ready for high-quality photorealistic rendering and animations.
LandXML File Types
There are three file
types you can import with the LandXML/DEM Model Import dialog: XML,
DEM, and DDF.
- XML is the most
robust file type for LandXML import. In addition to surface elevation
data, XML files can also contain Alignment (road) and Parcel data.
- The DEM (digital
elevation model) file type is the most commonly available large
area surface data type supplied by the USGS and other government
and private organizations. DEM files contain only surface data.
- The DDF file type
is an SDTS (spatial data transfer standard) format grid surface.
DDF files are very similar to DEM files; however, DDF information
is shared across multiple files.
The LandXML/DEM Model
Import utility searches for the key DDF file in the selected directory,
which is identified by the following pattern: xxxxCEzz, where xxxx is
usually numeric and zz typically 'L0'.
Like DEM files, DDF files
only contain surface data.
