→ Select **Load Roof/Floor Truss Types** directly from **Truss+** menu

* The command loads truss system grids, structural trusses and other structural framing families into the project.
* The command loads sample schedules into the project.
* Mark Definition Schedules allow to predefine or edit marking of elements at any time.
* To avoid this time-consuming operation, the user can save file as a template after loading families.
* Visibility settings depend on Detail Level.
* Other schedules can be used for scheduling trusses and structural framing elements in standard view and assembly views.
* Those sample schedules can be used as templates for truss assembly schedules.

You can find the families in **Project Browser** → **Families** under **Structural Framing**, **Structural Connections**, **Annotation Symbols** and **Generic Models** categories.

The command **Load Truss Types** loads:

* Truss System Grids
* Structural Trusses
* Nested Structural Framing families of Truss System Grids
* Structural Framing families of Truss Webs and Chords.
* Structural Framing families of Rafters

{% hint style="info" %}
**Note** Family name begins with “I\_Truss\_” for imperial units and with “M\_Truss\_” for metric units.
{% endhint %}

Default Metric and Imperial libraries are located here:

*C:\Users\user name\AppData\Roaming\TOOLS 4 BIM\2020 (or other version)\Wood Framing Truss+ RT\20.34.10627.0 (or other version)\Truss+\Libraries\Metric or Imperial\Library*

If you modify these families in the future, then you can hold them in your company template or place them in this catalog for upcoming projects.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.besmart.software/3d-modeling-and-design/metal-framing/feature-descriptions/truss-metal-framing/load-families.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
