# 4.3 Feature Pattern Interior Conditions
## Description
This module covers how to select a feature pattern truss and modify its interior conditions to accommodate a tray ceiling.
## Objectives
* Demonstrate how to select a feature pattern truss during component creation.
* Locate the Interior Condition settings tools.
* Customize and apply interior conditions to a truss.

Video Transcript:
Welcome! In this video, we will discuss feature pattern interior conditions and the tools for modifying them. Let’s get started.
Open the Component Creation panel and navigate to the predefined truss shapes. Select the feature pattern truss to move on to the feature pattern shape details. Here you will see some of the same inputs as profile trusses, such as length, depth and slope, but you will also see some new tools specific to feature pattern trusses. In this video we are going to focus on the Interior Conditions tools. This is where you can modify and define the interior conditions for your truss.
Within Shape Details, we provide a selection of commonly used interior conditions. You can apply multiple conditions to your truss simply by editing the settings. As you select these options, additional settings will become available that are relevant to the interior condition. Let’s take a look at the tray option for this example.
First we need to specify the distance the tray will be from the left side of the truss. Input 4 feet and hit tab to move on to the Step Up Distance. You should see the truss update in the scene. Now, we will leave the width at 8 feet but update the step up and down distance to 10 inches. Great, now we have a tray in our truss. At this point, you can select any other type of interior condition and it will save the changes you made for the tray and allow you to add an additional interior setting. If you need to edit or remove an applied interior condition, simply select the condition and make changes to the settings or click the delete button.
That wraps up this quick explanation of the interior condition tools available to you. We hope this gives you a better understanding of the tools at your disposal when designing feature pattern trusses. See you in the next one!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://training.paragontruss.com/c1-intro-to-paragon/4.0-creating-editing-and-analyzing-components/4.3-feature-pattern-interior-conditions.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
