How to add classification code to objects in Organizer and export it to IFC

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.

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.

Add Name, Property (no spaces) and change Property type to UDA.

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

6. Set value to custom property to add it to objects

Open the Category Properties dialog box of the lowest levels of the tree.

Add a value to the custom property that you want to write to the objects in the selected category.

7. Synchronize category tree to write to objects

Right-click any category under the root and select Synchronize the category to add the custom property and its values to the model objects.

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.

You can add only one classification code to the IFC export this way.

10. Export to IFC

No special settings here.

The classification code is exported with the assemblies or cast units.
