# Prompting

> Choose a model, connect an application, attach references and send your request.

Write what you want Ideatura to do in the message box at the bottom of a chat. Before sending, choose the application and references it needs.

## Choose an AI model

Click the model name beside the message box and select a model from the list. Keep the current model for your first task; you can change it for a later request in the same chat.

Where available, the arrow beside the model opens its thinking-level choices. A higher level gives the model more time to reason and can increase usage. It can help with complex geometry or a task that needs several decisions.

## Select a connected application

Open **Connected Apps** and select the open document you want AI to work on. Check the filename, especially when you have several projects open.

![Connected Apps menu with the open Revit document and Full access.](https://mintcdn.com/ideatura-preview/1xcbXOsazSQ_i7ak/alpha/images/setup/connected-current-project.svg?fit=max\&auto=format\&n=1xcbXOsazSQ_i7ak\&q=85\&s=92699adf8deffb6db9383f2b4e10bc0b)

The access label tells you what Ideatura may do in that application. **Full** permits changes. Use the options available for your connection; some modes offer only Full access. For a task using only attached documents, choose **No apps**.

If your application is missing, open its document first. If it still does not appear, follow the [add-in checks](https://beta.docs.ideatura.ai/alpha/essentials/updates.md#check-the-add-ins).

## Attach a reference

Click **Attach file** and choose the PDF, image or other document you want to use. Explain its role in your message:

> Use the attached PDF as the source for the room names. Update the names in the connected Revit project; keep the existing room numbers.

![Message box with an image attachment, the Attach file control and a request about the attached detail.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/image-attachment.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=0c4221b749fec4489403ae9df755d5b8)

You can also attach a markup from a viewer to point at a particular part of a drawing. Use **Skills for this message** to add reusable instructions; see [Standards and skills](https://beta.docs.ideatura.ai/alpha/essentials/standards-and-skills.md).

## Send and follow up

Click **Send**. Read the reply and inspect any drawing or model changes. You can continue in the same chat to answer a question or refine the result.

Click the square **Stop** button to interrupt a running request. This stops further work; it does not undo changes already made in the connected application.
