Take a list of Honeybee Rooms closed breps (polysurfaces) and split their Faces to ensure that there are matching coplanar faces between them.

This matching between Room faces is required in order to contruct a correct multi-room energy model since conductive heat flow won't occur correctly across interior faces when their surface areas do not match.

### Inputs

* **rooms \[Required]**

A list of Honeybee Rooms or closed Rhino breps (polysurfaces) that do not have matching adjacent Faces.

* **cpu\_count**

An integer to set the number of CPUs used in the execution of the intersection calculation. If unspecified, it will automatically default to one less than the number of CPUs currently available on the machine or 1 if only one processor is available.

* **run \[Required]**

Set to True to run the component.

### Outputs

* **int\_rooms**

The same input Rooms or closed breps that have had their component faces split by adjacent geometries to have matching surfaces.

# Agent Instructions: 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:

```
GET https://docs.ladybug.tools/honeybee-primer/components/0_create/intersect_solids.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
