The property pane and many dialog boxes contain user-defined attributes (UDAs) for various objects, including beams, columns, bolts and drawings. Tekla Structures displays these fields when you click the More button in the property pane or the User-defined attributes button in a dialog box. For example, comment, locked, and erection status are user-defined attributes.
When you define new user-defined attributes
The user-defined attributes are managed in the objects.inp file. To define new user-defined attributes, create your own objects.inp file in the model, project or firm folder. After adding your own user-defined attributes, you need to run the Diagnose and change attribute definitions command to update the definitions in the model.
When you define new user-defined attribute , make the definition of the user-defined attribute unique. This is because a user-defined attribute cannot have different definitions for different object types, such as beams and columns.
The object.inp files are merged so that if there are user-defined attributes in any of the files, they are displayed in the user interface. Tekla Structures merges the files in a way that eliminates duplicate attributes. If Tekla Structures encounters the same attribute name in different objects.inp files, the attribute from the first read objects.inp file will be used.
If you need to have several objects.inp files in the same folder, you can use a suffix in the file name to use all the files. This enables having several objects_<suffix>.inp files in the same folder. The file name could be objects_precast.inp , for example.
Do not copy the objects.inp file in the ..\environments\common\inp\ folder. Copying the file creates unnecessary duplicates and later objects.inp updates by Tekla Structures can be lost.
