# Automatic iProperties

“Auto iProperties” contains features that will allow you to create, fill, update, and synchronize the Inventor document iProperties automatically in the background, without your further intervention. This feature can **save you up to 100 % of the time** normally spent on custom iProperties updates.

{% hint style="success" %}
You start with an empty set of default iProperties, but when you click the Save button, all important iProperties get populated and/or created for you automatically. With each subsequent save of the document, the properties are automatically updated.
{% endhint %}

## Select or define your required iProperties

1. Go to Be.Smart T4I (ribbon) -> Be.Smart T4I (panel) -> Edit settings -> Auto iProperties tab and from the tabs `File`, `Physical`, `Drawing`, and `Sheet metal` select the iProperties you want to be automatically created/updated in the `Custom` tab of the document’s iProperties (see the examples at the bottom of this page).

{% hint style="warning" %}
Don’t forget to check the `Create property if needed (or update existing)` at the bottom left corner of the window.
{% endhint %}

{% tabs %}
{% tab title="FILE tab example" %}
For the assembly and part files only (in this case), `LastSaveDate` and `LastSavedBy` iProperties will be created/updated automatically.

{% endtab %}

{% tab title="PHYSICAL tab example" %}
The mass of the model (part or assembly) will be stored in the `Mass` iProperty (three decimal places, units included), and the dimensions of the part file bounding box (units in a separate iProperty, two decimal places) will be stored in `MaxDimensionX`/`Y`/`Z` iProperties.

{% endtab %}

{% tab title="DRAWING tab example" %}
A drawing paper size and the first view scale will be stored in their respective iProperties. Also, the `LastSavedBy` and `Mass` iProperties will be created/updated.

{% endtab %}

{% tab title="SHEET METAL tab example" %}
A flat pattern dimensions (extents) will be stored in the `SM_Extents` iProperty (length x width; two decimal places), and the individual sheet metal flat pattern dimensions thickness, length, and width will be stored in their respective iProperties (length and width will be stored as numbers).
