Points File (.txt) Export

Saves points to a delimited text file.

Both point coordinates and RGB color values (x,y,z,r,g,b) are exported.
For point objects, the color is taken from the point object's color.
For point cloud objects, if the point cloud has point colors, these colors are used. Otherwise, all points use the point cloud object's color.

On the File menu, click Export Selected or Save As.
In the dialog box, the Files of type list displays the currently supported file types for export.
In the Files of type box, select the supported file type.
In the File name box, select or type a file name.
Specify what is to be saved.

Options
Save small	Though clearing the render meshes makes the file smaller, it will shade and render more slowly the next time you open the file.
Save geometry only	Saves geometry objects only. No layers, materials, properties, notes, or units settings are saved. This is similar to exporting the objects. A new file is made, but it does not become your active Rhino model.
Save textures	Embeds external textures used by materials, environments and decals into the model.
Save plugin data	Saves data attached to objects or the document by plug-in applications.

If the export can be configured, click the Options button to specify export settings.
If the file type creates only mesh objects, in the Polygon Mesh Objects dialog box, specify the mesh settings.
