unique_attribute is a non-copyable attribute. The value of the attribute is never copied to another part. For example part checking status attributes usually cannot be copied.



Attribute name, used to find the attribute value.

Ensure that Tekla Structures does not already use the attribute name you use. Consider using a prefix that ensures the name is unique, for example, your initials, or an abbreviation of your company name.

The attribute name is case-sensitive. Do not use spaces or reserved characters in attribute names. The maximum length of the name can be 19 characters.

To include the attribute in a report or template, add the name of the attribute to your layout in the Template Editor. When you run a report or create a drawing, Tekla Structures displays the current value of the attribute.
