Files

Tools > Options > Files

The Files options manage templates, backup files, file saving and locking.

Template files

Location

Specifies the location of the template files.

Default

Defines the name of the template file Rhino uses when it starts. If a file is specified, this template is used when Rhino starts. If no template file is specified, a template list appears each time Rhino starts.

Save

Create backup (*.*BAK) files when saving or exporting

When enabled and a model is saved or exported to overwrite an existing file, the original file is renamed with an extension of .*bak.

  • The 3dm backup file (.3dmbak) can be opened by Rhino.

AutoSave

Save every ___ minutes

Turns on the Autosave feature and defines the save interval. When Autosave activates, a copy of the model you are working on automatically saves to the Autosave file.

Autosave file

Defines the name and location of the Autosave file. If a model has been saved, the Autosave file name will include the model name.

Always save before

Sets a list of commands that will save the file before the command starts.

Save render and analysis meshes in autosave file

If this setting is off, the model will save without meshes.

File Locking

Enable file locking. Creates *.RHL files

Rhino lock files <filename>.3dm.rhl are created to let other instances of Rhino know that a file is in use. Lock files are created when a .3dm file is opened or when an unnamed file is saved as a .3dm file.

  • If the extra dot in the locking file extension causes a problem on your system, in Advanced settings, setting Rhino.Options.FileSettings.RemoveDotFromRhlFiles=True changes the extension to .3dmrhl.

Display read-only warning

Displays in a warning message to a second user who tries to access a locked .3dm file with Rhino.

Note

  • Lock files do not prevent the file from being opened; they are only used to get information about who is using the file.
  • This information can display in a warning message to a second user who tries to access the .3dm file with Rhino.
  • If a lock file exists, Rhino lets other users open the related .3dm file only in read-only mode.
  • The lock file is automatically deleted when Rhino successfully closes the .3dm file.
  • If the Rhino file does not close successfully, abandoned .rhl files may prevent re-opening the associated Rhino file.
  • Abandoned .rhl files can be deleted.

Imported file layers

Controls how Rhino manages layer names when Rhino imports an external model into an existing model.

Ways to "import" an external model into the existing model include:

Example

Current model = ThreeStooges.3dm

Import models named CurlyHoward.3dm, LarryFine.3dm, and MoeHoward.3dm with the following layer structures.

ThreeStooges.3dm CurlyHoward.3dm LarryFine.3dm MoeHoward.3dm
Layers Layers Layers Layers
Name Name Name Name

Stooges

Curly

Larry

Moe

Faces

Curly

Faces

Larry

Faces

Moe

Use complete layer tree from source file

Rhino will create a copy of the imported model's layer tree in the existing model.

Result

The imported layers Curly, Larry, and Moe are merged into the same-named layers in the current model. The layer Faces is not merged.

Moe

Use existing layers with matching name

If a layer in the existing model has the same name as a layer in the external model, Rhino will add everything on the external layer to the existing layer.

Result

The imported layer Faces, with sub-layers Curly, Larry, and Moe below it, is imported without merging.

Clipboard

Allow copy and paste to version 7.0

When objects in Rhino 8 are copied and pasted to Rhino 7, new data in Rhino 8 will be converted or lost. Please make sure important information is not lost.

On exit

Specifies action to take when a large amount of data is in the Clipboard when Rhino closes.

Keep

Keeps data in the Clipboard for use in another application.

Delete

Clears the Clipboard.

Prompt

Prompts to keep or delete Clipboard data.

Recent files list

Clear Recent Files List

Removes file names from the list of recently-used files.
