Checkpoint

Lets you save and load versions of the current .wire file. You can use checkpoints to manage different versions of the model you are working on.

For example, checkpoints let you:

Quickly revert to a previous point in your current modeling session, such as an earlier version of a design.
Experiment with different iterations of your model in a non-destructive way.
Quickly make comparisons between different versions of a model.

By default, all checkpoint files get saved to the _checkpoints folder in your Alias directory. For example: C:\Users\<username>\Documents\Autodesk\Alias\_checkpoints. Depending on whether the files are auto-saved or manually saved, they are added to sub folders in the _checkpoints directory as follows:

Auto-saved: _checkpoints\Checkpoints\AutoSave
Manually saved: _checkpoints\Checkpoints.

Checkpoints Autosave options

Enable

Activate Checkpoint

When on, you can save checkpoints automatically according to the Interval Settings and at the Set Location.

Also, the following options display in the application title bar.

Auto Save - Saves a checkpoint automatically according to the Interval Settings and at the Set Location. By default, auto-saved checkpoint files get saved to the _checkpoints\Checkpoints\AutoSave folder in your Alias directory. For example: C:\Users\<username>\Documents\Autodesk\Alias\_checkpoints\Checkpoints\AutoSave.

Interval display \ Save Checkpoint Now - When you mouse over the interval display, Save Checkpoint Now appears. Click this to save a checkpoint of the current .wire file. By default, these checkpoint files get saved to the _checkpoints\Checkpoints folder in your Alias directory. For example: C:\Users\<username>\Documents\Autodesk\Alias\_checkpoints\Checkpoints.

Interval Settings

Checkpoint Interval Type

Choose the criteria used to trigger a checkpoint save when the set Interval Value is reached.

Commands - Saves a checkpoint based on the number of executed commands. Pick-related commands, such as Pick CVs, are not counted as a command execution.
Minutes - Saves a checkpoint based on minutes.

Checkpoint Interval Value

Sets the number of executed commands or minutes between each checkpoint save.

Disk Settings

Use these options to manage the disk space used by the set Checkpoint Directory.

Max File before Overwrite/Max Disk Usage (Mb)

After these numbers are reached, older checkpoints are deleted to make room for new ones.

Current Disk Usage (Mb)

The current amount of space used on disk for all checkpoint files.

Set Location

By default, checkpoints files get saved to a _checkpoints folder in your Alias directory. For example: C:\Users\<username>\Documents\Autodesk\Alias\_checkpoints. When you specify a custom location for your checkpoint files, Alias creates a subfolder called Checkpoints. The user and auto saved files are saved to this location.

Important: Alias 2024 and Alias 2024.1 Update users note the following:

If you used Checkpoints in these versions, be sure that the Checkpoints directory is not set to the same location as your working files. Otherwise, by default, these will be deleted along with the checkpoint files when you exit Alias.
If you set your Checkpoints folder to a custom location, you need to move them to either the new Checkpoints or _checkpoints directory in Alias 2025. Otherwise, they will not be visible in the Checkpoints window.

Set in General Preference

Click this to set the directory path for the Checkpoint File Location. This option is located in the File Paths section of the General Preferences window.

View Directory

Opens the currently set Checkpoint File Location. Use this option to access the directory for deleting checkpoint files if necessary.

More Settings

Delete Files on Exit

Deletes all checkpoint files when you exit Alias.

Attempt Save on Crash

Saves checkpoint to the current to the Checkpoint File Location if Alias exits unexpectedly.

Note: This option works similar to the way that MSave files get created when Alias exits unexpectedly, but it does not replace them. When on, files are saved to the Checkpoint File Location and MSave File Location simultaneously.

Checkpoint Files

Displays the list of autosaved and manually saved checkpoint files with filename and timestamp.

Turn on Auto Saved Files and User Saved Files to display these in the list. Choose either Newest First or Oldest First for the order in which files appear.

Open Selected

Lets you open multiple checkpoint files from the list. Use Ctrl - select or Shift - select to choose multiple files from the list.

Save a Checkpoint

Saves a manual checkpoint of the current .wire file. By default, these checkpoint files get saved to the _checkpoints\Checkpoints folder in your Alias directory. For example: C:\Users\<username>\Documents\Autodesk\Alias\_checkpoints\Checkpoints.
