# Creating and Managing Projects

{% embed url="<https://youtu.be/cXJBVl62I1o>" %}

{% hint style="info" %}
Each Hamina project is designed to model one building at a time. Use separate projects when working with multiple buildings for most accurate results and greatest performance.
{% endhint %}

To create a new project, click on the **Project drop-down menu**, and then the **+ New project** button at the bottom of the menu.

The **Create First Project** window will appear, which contains several settings.

#### Project name

Defines the name for the project. If you are working on a named building, this is a good place to put it.

#### Country

Defines the regulatory domain of the network, and will determine which Wi-Fi channels are available for use.

#### Environment

The **Environment** configures two aspects of the project:

1. How much attenuation to apply to the map if the prediction mode is set to **Env Type (PLE)**. This usually only happens when there aren't any walls or attenuating objects on the project. Learn more about switching prediction modes in [Heatmaps](/hamina/basics/heatmaps.md#simulation-models).
2. Sets the minimum ceiling height on maps in the project that haven't been added to the building with the **Align floors** tool. Learn more about this in [Managing Maps and Floors](/hamina/guides/maps-floors.md#ceiling-heights).

{% hint style="success" %}
While the environment type and "blanket attenuation" is good for rough AP count estimations, for true network designs, we recommend drawing walls and attenuating objects.
{% endhint %}

{% hint style="info" %}
If you need to model free space (such as a network in an open field), choose the **Free Space** environment type, which not apply any blanket attenuation to the project.
{% endhint %}

#### Project folder

Projects can be grouped together with folders. You can use folders to group together projects on a campus, by larger project, or by customer.

Folder and sub-folders can be created by adding forward slashes. For example:

`Area A / Campus A / Building 1`

`Area A / Campus A / Building 2`

`Area A / Campus B / Building 1`

<div align="left"><figure><img src="/files/UvPtQBwrTevurNIqU2V1" alt="" width="375"><figcaption></figcaption></figure></div>

{% hint style="info" %}
If the project is shared with another user (either individually or as a team), they receive the same folder structure. You will also receive any edits made to the folder structure.
{% endhint %}

# 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.hamina.com/hamina/basics/creating-and-managing-projects.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.
