This article describes how to create attributes for use with items and parts. 


For issues, the process of defining attributes is the same except that they are created in a CMS project, and not in the swArchitect.


Prerequisites


For creating attributes for items and parts, log in to the server using the swArchitect client and navigate to the Attributes tab. 



To create an attribute, right-click in the pane and select Create



The Create Attribute Type dialog provides a number of settings for defining the attribute. They are described below. Make your selections and click OK to save. The new attribute will be included in the list of attributes in the Architect.



SID: The attribute's unique identifier. Can include letters, numbers and special characters (maximum length: 8 characters) although it is recommended that only letters (A-Z) and/or numbers (0-9) are used. (required)

Name: Name of the attribute as seen by the users. (required)


Tip: Keep in mind that the length of the attribute label display is limited in Overview, in order to allow for sufficient room for display of values. Therefore, attempt to keep labels short and concise but, if attribute names are similar and do get truncated, place the differentiator at the beginning. Example:


Data type: Defines both the data dimension and the attribute type. Data type is required and the data dimension and data type options are: 


SingleThe attribute can have one value.
ArrayThe attribute can have several values. Allows duplicates.
SetThe attribute can have several values from a validated list called a "Range".


A drop-down list of available types is provided. A selection is required and the following types are available:

Optional

The following standard settings are optional:

Info: A text box used for administrative information, e.g., the purpose of the attribute, who created it and when. 


Default value: Set a default value upon creation of new items or parts of types that have the attribute as a default attribute. The table above shows whether a default value is supported or not for each attribute type.


Allow empty value: Indicates if empty attribute values should be acceptable or not. Check the box to allow an empty value. If a value is not set for an attribute where an empty value is not allowed, a warning icon will display to indicate that a value should be set. 


Editor width: Sets the default width for displaying the attribute values. 200 is a good starting point. This option is available for all attribute types.


Editor min height: Sets the min height for displaying the attribute values. Applicable only to Text type attributes where there may be multiple rows of text. 


Editor max height: Sets the max height for displaying the attribute values. Applicable only to Text type attributes where there may be multiple rows of text. 


Restricted: Check this box to hide the attribute from users in the standard views. Such information would typically be visible in some other form.


Fixed font: Used in special cases to indicate that a fixed size font like Arial should be used for presenting the value. An example can be attributes used for code snippets. 


Deprecated: When selected, indicates that the attribute is no longer used. Users can still view the attribute, but will see a warning icon next to the deprecated attribute. 

To hide the attribute, use together with the Restricted option. 


There may be additional settings available for specific attribute types. They are described in separate articles.
