The video covers adjusting the orientation for a single truss envelope and for multi-selected truss envelopes. {% hint style="warning" %} Warning Be sure to use `Flip Envelope` to finalize truss orientation prior to designing trusses. {% endhint %} ## 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 Watch video and follow along within the Paragon Design App. {% embed url="" %}
Video Transcript: 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!

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/c3-intermediate-layout-and-design/5.0-create-truss-envelopes/5.6-flipping-truss-orientation.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.
