# Interface Overview
Welcome to Paragon Materials! Let's dive into the different sections of the interface.

**Note**
Access to certain features and functionality may be restricted by your plan type.

## Home Screen
The interface is pretty simple and consists of three columns.
* Lumber Lists
* Plate Lists
* Hanger Lists
At the top of each column you will find a `+` button that allows you to add a new list.
## Lumber List
This interface is fairly simple with options to create a new lumber set or edit/delete an existing one. There are also options to Make this the default, rename a list, duplicate or archive it.
## Plate List
The interface allows you to define specific groups of plates to use for component designs. It is possible to create multiple plate lists per manufacturer or take advantage of ComboPlate which involves creating a single Plate List with plates from multiple manufacturers allowing you to swap out plate during fabrication.
Similar to the Lumber List, there are options to Make this the default, rename a list, duplicate or archive it.
### ComboPlate
Use `Make this a ComboPlate List` for additional flexibility during fabrication. [ComboPlate](https://docs.paragontruss.com/design/explanation/comboplate) allows you to create plate lists with different plate manufacturers. When you run plate upgrades on a truss, plates will be checked for the lowest common denominator design values at the joint, and all included types will be reported on the Truss Design Drawing, shop drawings, reports, etc.

Tip
When building your plate list, use the `Filters` to reduce the number of plates presented to you making it easier to select plates by Manufacturer, Type, and Size.
Use `Hide unused plates` and Size when reviewing and modifying your plate list.
{% endhint %}
## Hanger List
The interface allows you to select from a list of supported hanger products. Hanger products that are included in the project's materials will be available for selection in Paragon Design.
Similar to the Lumber and Plate Lists, there are options to Make this the default, rename a list, duplicate or archive it.
