1. Introduction

This document describes the workflow how to add a classification code to objects with Organizer Categories and how to export the code with the objects to an IFC file.

The IFC export writes classification information to assemblies and cast units, but not to parts.

2. Classify model objects in Organizer

Create the classification categories that you need in the Property category section in Organizer Categories. Add assemblies or cast units to the categories.

Property categories have circular icons.

3. Create custom property for classification code

In Organizer Settings, create a custom property that corresponds to the classification system you want to use. Custom property is a UDA. To see the custom property in the User-defined attributes dialog box, you need to add it in the objects.inp file.

Now all subcategories under this root have the same custom property. The lowest subcategories will add it to the objects with the given values.

9. Add classification code to IFC export

To open the Tekla Structures Project dialog box, go to File > Project properties > User-defined attributes.

Add the name of the classification system that you used. It should be the same name that you have in Property field in the View Property dialog box.
