# Virtual Intersections
**Top & Bottom Virtual Intersection** - virtual intersection means that elements do not actually intersect but they would if extended. So, you have to use Min and Max distances to search for possible virtual intersection with selected Category elements and Types.
{% hint style="info" %}
This applies to **analytical lines** of elements, for example, **Structural Framing analytical lines**, which may not align perfectly due to modeling settings or analytical adjustments.
Note that **Structural Framing analytical lines** can be shifted vertically using the **Z Justification** parameter — this can affect how intersections are detected.
{% endhint %}
***
**Left & Right Virtual Intersection** - same as above, but searching direction is different.
When selected **category f**or Left & Right Virtual Intersection **is “Structural Framing”**, an **additional feature** becomes available called ***Intersecting Detail Orientation***.
This feature allows users to specify the **orientation of the structural framing elements** — for example, studs or joists — as either **horizontal** or **vertical**. The chosen orientation determines how framing elements interact with other parts in the model and how nailers or other connection components are assigned.
**Functionality Overview**
* **Horizontal Orientation:**
* Use this setting when framing elements (such as studs or beams) run horizontally.
* When selected, ensure the **layout is applied** to manage the **distribution of elements** along the layout path.
* This allows for even spacing and proper alignment of intersecting details or connection parts.
* **Vertical Orientation:**
* Use this when framing elements run vertically (e.g., typical wall studs).
* This orientation ensures that connection parts (like nailers or plates) are correctly aligned and attached to the corresponding vertical members.

## 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://docs.besmart.software/3d-modeling-and-design/smart-connections/configuration-window/adjust-layout-by-searching-for-other-elements/virtual-intersections.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.
