+Similar to raster and vector layers, point cloud layers can be saved in a different
+format and/or reprojected to a different coordinate reference system (CRS).
+This allows you to export a point cloud layer to vector or point cloud formats.
+Current supported formats are: Temporary scratch (memory layer), GeoPackage, ESRI Shapefile,
+DXF and LAS/LAZ point cloud.
+In addition to the common parameters listed above, exporting point cloud layers includes the following options:
+
+* :guilabel:`Filter by Polygon Layer`: Allows you to filter the point cloud data based on a polygon layer.
+* :guilabel:`Elevation Range`: Enables filtering of the point cloud data based on a specified Z range.
+* :guilabel:`Limit number of points`: Provides an option to limit the number of points exported from the point cloud layer.
