The name should be changed to distinguish the new profile map from the copied one, but it can be changed in the new row or in the Settings window from clicking the Edit button.
Edit
Clicking the Edit button allows editing of a newly created profile map or an existing one from the profile map Properties page. The Edit Properties page has two sections: the top section for defining the profile map name and type and the main section which contains a grid for setting the relationships between the part’s properties and the values in Tekla Structures.

The profile string for the L Beam has the form “LBEAM a*b*c*d*f” where each letter represents a property in the beam’s cross section. Each letter’s position in the string is the index value to be entered in the the Index/Value column.
The properties for the beam’s cross section from Tekla Structures can then be related to the properties in the profile map window. For example, the Overall Height in Tekla Structures is represented by the Symbol 'a' in the profile string which is the first value in the string, so the Overall Height property in the profile map window will have an Index of 1. This value is variable so the checkbox in the Is Constant column will remain unchecked. The indices for the rest of the properties are added in the same way.

Once all fields and values are added in the window the Okay button must be clicked to accept the new profile map. Then, the Okay button on the Supported Profiles Settings window must be clicked to add the new profile map to the list of supported profiles.
