Rename Model: Rename the selected model in the project. This option exists only when the model is associated with a project.
Remove Model: Remove the selected model from the project. You will be prompted to remove the model from the disk.
Choose Yes to delete the model from your hard drive.
Choose No to remove the model from the project but not from the hard drive. It is saved in the project folder and can be added back to the project or to another project at a later time.
This option exists only when working with a model that is associated with a project.
Project files
This following covers topics that are related to working with project and model files in the file structure on your hard drive.
Project folders
When you create a project, a project folder is created in the chosen location and a project file (.pjt) is created within the project folder.
Note: When you enter the name of a project in the Create New Project dialog box, the project folder takes on the same name. Changing the project name using the Rename Project function will also change the folder name.
The following figure shows a typical project folder on the hard drive. The folder contains the
“parent” project (.pjt) file and the “child” model (.mdr) files.
A project folder and its contents
You should use Modeler software to manage projects and models whenever possible.
Moving, renaming and deleting project and model files in the file structure on your hard drive is not recommended. For example, to copy a model, use the “Duplicate Model”, or
“Save Model As...” functions in Modeler software rather than copying the model file on your hard drive.
Renaming, moving, and deleting model files
A project file (.pjt) must be located in the same folder as its “children” models in order for Modeler software to recognize and open the project. Actions carried out in the file structure may cause the project to be “out of sync” in Modeler software. Moving, renaming, or
deleting “child” model files (.mdr) in the file structure of your hard drive will cause an error message when opening the “parent” file in Modeler software.
Renaming a file
If you rename a model file (that is associated with a project) on your hard drive, Modeler software will be unable to find the model when you open its “parent” project. You will be prompted to locate, skip, or remove the model file from the project. For example, suppose you renamed the “Design 2” model in the previous figure to “Design 3”, as shown:
Renaming the Design 2 model
When you open the “Small Theatre” project in Modeler software, you will receive the Project Error message:
Project Error message
Locate...: Will allow you to search for the model file.
Skip: Will open the project without the “Design 2” model. (If you select skip, you will receive the same error message every time you open the project until the model is either located or removed).
Remove: Will remove the model from the project.
Moving a file
If you move a “child” model file from its project folder and then try to open the “parent”
project in Modeler software, the program will be unable to locate the model file. You will receive a Project Error message. Clicking Locate... will allow you to find the file on the hard drive. Once located, the model will be added to the project.
Deleting a file
Deleting a model file from a project folder on the hard drive will also cause the Project Error in Modeler software when you try to open the project. You will be prompted to locate, skip, or remove the model from the project. If you select skip, you will receive the same error message every time you open the project until the model is either located or removed.
Renaming, moving, and deleting project files
A project file (.pjt) must be located in the same folder as its “children” models in order for Modeler software to recognize and open the project properly.
Rename: You can renamea project file in the file structure, but it is recommended that you rename projects in Modeler software. If you rename a project file in the file structure of your hard drive, the project will still open properly and all models will remain associated to it. However, the project folder will not be renamed, and will retain the original project name. This may cause confusion when working in Modeler software.
Move: If you move the project file from its folder to another location, and then open the project, Modeler software will be unable to locate the “child”
models because they are no longer in the same folder as the “parent”. You will receive an error prompting you to locate, skip, or remove the missing model files. If you select skip, you will receive the same error message every time you open the project until the models are either located or removed.
Delete: If you delete a project file, you will be unable to open the project. You will need to create a new project and add to it all models previously associated with the deleted project.
