# AdapterForIfc

**AdapterForIfc** extracts graphics and attributes from *Industry Foundation Classes (IFC)* files and saves them in a `.upvc` file. This file is then used as input for the **Builder** to create UPV models.

Note: As of version 2026.3.4, the AdapterForIfc correctly decodes the IFC GlobalId to the internal UID.
If you would like to keep the previous behavior, please add the following entry to the INI file located in %appdata%\CAXperts\IFC Adapter\<username>.ini:

```
[IFC Adapter]
DecodeUidFromGlobalId=0
```
