{% hint style="warning" %}
If an iProperty is missing in a *Custom iProperty* section of the document, it is necessary to check the option *Create property if needed (or just update existing)* in the bottom left corner of the settings window).
{% endhint %}

{% hint style="info" %}
Only document-relevant iProperties will be created/updated in the document. It means that e.g. sheet metal properties will not be created/updated in the assembly file.
{% endhint %}

The iProperties will be automatically created after saving the document.

### Workflow example

Given the specific settings for the assembly file depicted in the images above, four iProperties were automatically added to the document: *Filename*, *LastSaveDate*, *LastSavedBy*, and *Mass*.
