SUBTYPE
This is a template attribute. Template attributes can be used in filtering, or to retrieve data from the model to use in drawings and reports. For example, when you create a report, Tekla Structures replaces the attributes added in the report template with the corresponding object property values.
This template attribute shows the subtype of a profile. The subtype options vary depending on the profile. For example, for fixed steel profiles, the subtype could be cold rolled, hot rolled, or welded.
For parametric profiles, the subtype usually lists the profile parameters (or property symbols) in a formula-like format, for example, s*h-b*h2*h1 for RCX concrete ledger profiles.
