Model Files

When you create or edit a model, it is displayed in the working window. The filename of the model is displayed on the status line. If you have not yet given the model a filename, the default name new model is displayed.

You may:

Create a new model in the working window using a template (\new)

Open and edit an existing model (\open)

Open and edit from an existing model (\openas)

Save the model under any filename on your disk (\saveas)

When you open an existing model, you are actually working on a copy of the file and not on the original disk file. If you save under another filename, the original file remains unchanged. If you save under the original filename, the original file is replaced. If you regret the changes you have made, you may leave the file without saving it.

By saving under different filenames, you may create several different versions of a model, each based on the same original but stored in its own separate file.

A typical working process is shown in the following example:

	Action	Result
Work Session 1	Create Model
	Save model under name Project1	Model is stored on disk
Work Session 2	Open Project from disk	Model is copied from disk
	Edit the model
	Save under original name Project1 or	Original model on disk is updated
	Save under new name Project 2 or	Original model project1 is unchanged New model project2 is saved on disk
	Exit without saving	Original model project1 is unchanged Current editing is abandoned

Filenames

ARC+ stores each design in three model files. These have the filename that you specify and file extensions .ddd, .iii and .adb. If you wish to copy or delete a model outside the ARC+ environment, be sure to include the .ddd, .iii and .adb files.
