How to create, edit and delete project properties in p:IGI+

Project properties let users add fully functional properties to a project so they can view, calculate and use custom/proprietary data not accommodated in the IGI property model.

Creating project properties

Step 1: Create the project property

Go to Data Project property… New

Choose the property type:

- Standard Text

- Standard Numeric (numerical properties without indicators)

- Gas Numeric (numerical properties with gas indicators)

- Molecular Numeric (numerical properties with molecular indicators)

Complete the required fields in the creation dialog for the chosen type:

- Give the property a short & long name

- Choose the Analysis Group in which you’d like the property to reside
  - Custom is recommended to differentiate user and IGI properties

- If your property is a ratio, select Property is a ratio quantity

- Choose the relevant unit details for your property

- If applicable, enter an equation
  - Define all equations in a direct a/b form
  - Any properties for ratios existing across several analysis groups cannot be created by the user.

- Click OK to add the property to the project

After creation, project properties behave like any built-in property.

Note: Project properties exist only inside the project (it is not possible to upload them to a Metis database). Project properties can be transferred to other projects via exporting/importing artefact templates.

Editing project properties

It is possible to edit the name and/or equation for a project property. If further edits are required, it would be necessary to create a new project property, copy any data to this new property and delete the original.

Step 1: Editing a project property name

Go to Data Project property… Edit names…

Select the required project property

Only project properties will appear in the property selector

Make the required changes to the New short name and/or New long name fields

Select OK

Step 2: Editing a project property equation

Go to Data Project property… Edit equation…

Select the required project property

Make the required changes to the equation

Edits to the equation are accompanied by a validation to ensure equations are viable.

Select OK

Deleting project properties

Follow either Step 1 or Step 2.

Note: If you delete a project property, artefacts that use it will also be deleted unless you first remove the property from those artefacts.

Step 1: Deleting a project property immediately after creation

To remove a project property immediately after creation, use Undo (Ctrl+Z or the Undo shortcut icon). This will fully remove the property and any associated data.

Step 2: Deleting a project property not immediately after creation

Go to Data Project property… Delete

Choose the relevant project property

Click Analyse

This will return a list of all artefacts that are using the project property

Click Delete
