You can also export point cloud data to the Autodesk SDF format. You can
connect to a point cloud SDF file as you would to any SDF data store. Exporting
your point cloud data to SDF format is useful for creating geospatial features
from LiDAR data.
NOTE Because point clouds can contain millions or billions of points, SDF files
created from point clouds can be very large. Before you export your point cloud
to SDF format, filter the point cloud down to the smallest usable size. For best
performance, filter the point cloud down to one million points or fewer.
NOTE You cannot export point cloud data from an index file created using
AutoCAD commands (.PCG file).
To export point cloud data to LAS or ASCII formats
1 Right click the point cloud or point cloud layer you want to export, then
select Export Point Cloud. The Export Point Cloud dialog box appears.
2 Select the file type to which you want to export your point cloud data
in the File of Type field.
3 Specify a file name and save location.
4 Click Save.
To export point cloud data to Autodesk SDF format
Before you export point cloud data to SDF format, use the Point Cloud Manager
(page 1897) to create a filtered point cloud containing only the necessary points.
For best performance, filter your point cloud down to one million points or
fewer.
1 Right click the point cloud or point cloud layer you want to export, then
select Export as SDF. The Export Point Cloud as SDF dialog box appears.
2 Specify a file name and save location.
3 Click Save.
Mapping Drawing Attributes to Feature Class Properties
You can map drawing attribute properties to feature class properties when
you export DWG data to the SDF format. You can also map specific values of
the AutoCAD drawing properties .COLOR, .LINETYPE, and .LINEWEIGHT to
specific feature class property values. For example, you could specify that all
