# 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.

![AI model and thinking-level controls beside the message box.](https://mintcdn.com/ideatura/V8OOHfG85Urp1laS/images/studio-tour/model-effort-closeup.svg?fit=max\&auto=format\&n=V8OOHfG85Urp1laS\&q=85\&s=7a6762f93c5d2a2991b441708e9a4176)

## 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/ikzSFCYeQEUdwMtU/images/setup/connected-current-project.svg?fit=max\&auto=format\&n=ikzSFCYeQEUdwMtU\&q=85\&s=267bc83e65db6addf1ccf9cc95bf3398)

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://docs.ideatura.ai/v2/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/EJ_V0rHUL0H7t8B0/images/viewers/image-attachment.svg?fit=max\&auto=format\&n=EJ_V0rHUL0H7t8B0\&q=85\&s=afe1220e935a1dea7a534ad023e98a22)

An attached reference appears above your request. This example uses an image to ask about a detail.

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://docs.ideatura.ai/v2/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.

![A running request with the square Stop button marked 1 at the bottom right.](https://mintcdn.com/ideatura/tQ9E6REhgvkf2Hho/images/studio-tour/stop-request.svg?fit=max\&auto=format\&n=tQ9E6REhgvkf2Hho\&q=85\&s=dd04a6dd91483e31faa898fe01ff465a)
