AutoCAD (.dwg, .dxf) import/export

A binary file format used for storing two and three-dimensional design data and metadata. It is the native format for several CAD packages including AutoCAD.


To open, import, insert, and attach a file as a worksession

  1. From the File menu, click Open, Insert, Import, or Worksession > Attach.

  2. In the dialog box, select a supported file type.
  3. Click Open and configure the settings.
    When you open a non-3dm file and save the model, its filename will be the default 3dm filename.

DWG/DXF Import Options

Import unreferenced layers

Imports empty layers.

Import unreferenced blocks

Imports unused block definitions.

Import unreferenced linetypes

Imports unused linetype definitions.

Convert wide polylines to surfaces
Ignore thickness
Convert regions to curves
Mesh precision

If the mesh imported from DWG/DXF is too big or too far from the origin to work properly as a single-precision mesh, Rhino will import the mesh as double precision.

Double precision
Single precision
Model units
Layout units
Set layer material to layer color

Assigns a material to each layer that matches the layer color.

Always use these settings. Do not show this dialog again.

Saves the current settings and turns off the dialog display.

Command-line only option

VerboseOutput (Yes/No)

Set yes to display information of bad objects reported by the Check command in the command-line. Bad objects will not import. It is recommended to leave this option off unless you have a reason to turn it on.

Import notes


To save as or export a Rhino model

  1. On the File menu, click Export Selected or Save As.
  2. In the dialog box, the Files of type list displays the currently supported file types for export.
  3. In the Files of type box, select the supported file type.
  4. In the File name box, select or type a file name.
  5. Specify what is to be saved.
  6. 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.
  7. If the export can be configured, click the Options button to specify export settings.
  8. Mesh file types export NURBS surfaces as meshes either with the specified meshing options, or the document render mesh settings.

Edit Schemes

Opens the AutoCAD Export Schemes dialog box.

Export DWG/DXF with an external scheme file

To ensure all Rhino users in a corporation export dwg/dxf files with the same scheme settings, use the scriptable version of the Export command: -Export

To prepare the scheme file

  1. Use the AcadSchemes command to create a customized scheme.
  2. Click Export... to save an AcadExportScheme File (*.ini) file.
  3. Open the ini file in a plain text editor, for example, Windows Notepad.
  4. Change CurrentOption=n to CurrentOption=y.
  5. Save the file.

To use the scheme file to export

  1. Start the -Export command.
  2. Type the file name, for example, my.dwg or my.dxf.
    The full path of the file can be included.
  3. At the Write file using scheme... prompt, select the FromIni option.
  4. Browse to select the scheme file or enter the full path of the file.
  5. Continue to finish exporting the dwg/dxf file.
