## Description

This module demonstrates how to use `Flip Envelope` to align the left end indicators for similar truss envelopes. The video covers adjusting the orientation for a single truss envelope and for multi-selected truss envelopes.

Be sure to use `Flip Envelope` to finalize truss orientation prior to designing trusses.

## Objectives

* Explain why it's considered a best practice to align the left end indicators when possible.
* Demonstrate how to use `Flip Envelope` for one or more selected truss envelopes.

## Additional Resources

* Training Plan 3 accessible from Choose/Create Project > OPEN SAMPLE

## Learning Activity

<summary>Video Transcript:</summary>

In this video, we’ll show you how to flip a truss envelope to ensure each truss envelope has the correct left end defined. The left end is marked by a green triangle, known as the left end indicator.

Let’s get started. We’ll pan over and zoom into the fireplace area. Here, you can see the bottom-most truss has the left end indicator on the opposite side compared to the other three trusses. To fix this, click to select the truss, then go to the Properties panel and choose Flip Envelope. Now, all the left end indicators are aligned.

As a good practice—and to match the completed training file—we’ll also adjust the valley trusses over the garage, so that their left end indicators are on the opposite side. This is more of a personal preference, but it helps maintain consistency.

Let’s Ctrl click and move the mouse. Doing so, the multiselect menu appears. Here we will select Truss Envelopes from the menu. Then, while holding down Ctrl, click and drag across the garage valley trusses to select them. Once they’re selected, go to the Properties panel and click Flip Envelope. Now, all of the valley trusses are aligned with the orientation of the reference file for easy comparison.

Let’s take one final look in the 3D view. Everything looks great.

Aligning the left end indicators consistently across similar trusses improves accuracy and makes your layout easier to follow. We hope this quick video gave you the confidence to make these adjustments and keep your trusses aligned correctly.

Thanks for watching!
