# 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.

![Full Studio window with Connected Apps open and the Garden Office Revit document selected.](https://mintcdn.com/ideatura-preview/A4P0pD6lf12o5ClV/beta/images/studio/windows/portrait-integrations-revit-connected.png?fit=max\&auto=format\&n=A4P0pD6lf12o5ClV\&q=85\&s=6e3f5063a72b2201956c797b4a6fce98)

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/beta/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:

> Review the attached cabinet drawing. Check the dimensions and flag any missing information before I issue it.

![Full Studio window with Cabinet\_Review\_Rev\_B.pdf attached and an unsent request to review its dimensions and missing information.](https://mintcdn.com/ideatura-preview/A4P0pD6lf12o5ClV/beta/images/studio/windows/portrait-composer-real-pdf-attachment.png?fit=max\&auto=format\&n=A4P0pD6lf12o5ClV\&q=85\&s=8b34138bc2c286e543b19856fce99d4e)

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/beta/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.

![Full Studio window with an active demo request and the native Stop button.](https://mintcdn.com/ideatura-preview/A4P0pD6lf12o5ClV/beta/images/studio/windows/portrait-composer-stop-button.png?fit=max\&auto=format\&n=A4P0pD6lf12o5ClV\&q=85\&s=7c514280c95465cc01fb1a1fd14291ca)
