Creating Surfaces From Survey Data
AutoCAD Map 3D 2011 allows you to create GeoTIFF raster surfaces from
point data. You can enter point data in a variety of text formats as well as
from AcDb point data and block references in your drawing. AutoCAD Map
3Dalso supports LandXML data sources that include a surface element; you
cannot use a LandXML data source that contains only points.
If you are adding data from an ASCII point file and your text file contains
lines that do not represent point data, enter a # character at the beginning of
such lines. AutoCAD Map 3D ignores all text lines that begin with the #
character.
AutoCAD Map 3D creates a raster surface in GeoTIFF format from the data
you enter and adds it to your map as a feature layer. You can then style your
surface using all of the visualization and styling tools of the Display Manager.
You will also see a new Raster connection in the Data Connect window.
To create a surface from a source file
1 In the Tool-based Ribbon Workspace, click Create tab > Surface panel >
3D Surface or enter MAPCREATESURFACE at the command line.
