Filters can be created, edited and saved in the **Edit characteristic filter** window. The window is only accessible when a drawing sheet is open. Then click on **Filter characteristics** ({{:en:infra-convert:user:interface:icon_filter2.png?nolink&15|}}) or **Edit characteristic filter** ({{:en:infra-convert:user:interface:icon_arrow_down.png?nolink&10|}}) directly next to it in the main toolbar.

==== Structure ====
The current filter criteria can be viewed and edited in the main area of the window **(3)** . The management tools are located in the header on the right **(2)**. The name of a filter is displayed on the left **(1)** if it is a saved filter. An asterisk (*) next to the name indicates that the currently set criteria differ from the saved criteria, i.e. they are not saved.
