# Linework

Lines and arcs included in families are imported into Revit.

To control their appearance, assign a subcategory to the curves that matches one of the subcategories available in the Revit family template. 

{% hint style="info" %}
For example, assigning the subcategory \<Hidden Lines> will display the curves using that style inside Revit.
{% endhint %}
