Build a simple house directly in Studio. This example needs no Revit, AutoCAD, Rhino or Blender connection and no existing model. [Install Studio and sign in](https://docs.ideatura.ai/v2/essentials/installation.md) before starting. ## Send first prompt After your first sign-in, Studio opens an empty **New Conversation**. You can type your first request here. If you already have a conversation open, click the pencil button at the top right to start a new one. ![Complete Studio window with an empty New Conversation, sidebar, model picker and message box.](https://mintcdn.com/ideatura/wAMHb3mEOTJ5C3fT/images/v2/studio-first-conversation.png?fit=max\&auto=format\&n=wAMHb3mEOTJ5C3fT\&q=85\&s=1c1ca82ee7c85c8487beb5e1f8bb974e) Studio after first sign-in: an empty conversation, with the message box below and the viewer closed. Open **Connected Apps** beside the message box and leave **No apps** selected. Choose a **Sol** model in the AI model picker for this example. Your account needs access to it. The house below was generated with **GPT-6 Sol** in **Direct** mode; your model list may show a newer Sol version. Paste this into the message box and click **Send**: > Create a simple single-storey house as an IFC model. Use metres: an 8 × 6 m rectangular footprint, a ground-floor slab, four external walls 3 m high and a gable roof with its ridge along the 8 m direction. Use light walls and a dark roof. Keep this first version simple, with no interior partitions, doors or windows. Give me the IFC file and open a 3D view so I can inspect it. ![Complete Studio window with the house prompt entered once and the Send button at the bottom right.](https://mintcdn.com/ideatura/wAMHb3mEOTJ5C3fT/images/v2/studio-first-prompt.png?fit=max\&auto=format\&n=wAMHb3mEOTJ5C3fT\&q=85\&s=971346940a3e46643bb2e47d9faec0ba) The request in Studio's message box, ready to send. The model picker above it shows the model available to this account. Wait for the reply and file card. AI may ask a question; answer it in the same chat. Your file name and some modelling details may differ from this example. ## Open and inspect the result Click **Open** on the IFC file card if the viewer has not opened beside the chat. Use **Fit scene in isometric view** to see the whole house. Choose **Orbit** from the navigation menu to look around it, and use the mouse wheel to zoom. ![Actual Studio conversation and generated IFC house in the 3D viewer.](https://mintcdn.com/ideatura/MJ3FvHQFVwvFuYO5/images/v2/house-first-result.jpg?fit=max\&auto=format\&n=MJ3FvHQFVwvFuYO5\&q=85\&s=411ca53bb1aaedb0d020eded7050270e) The first result: a simple house with light walls and a dark gable roof, generated in Studio with No apps selected. Check that the slab, four walls and roof are present. Use **Structure** to find elements and **Details** to inspect a selected element's information. Read the reply for any assumptions, such as roof pitch or wall thickness, that the prompt left open. ## Refine it in the same chat Ask for one specific change: > Change the roof colour to terracotta red. Keep the house dimensions, wall colour and geometry unchanged. Return the updated IFC file. Open the updated file card and inspect it. Keep using this chat to refine the same house; start a new chat for a separate task. ![The follow-up prompt beside the IFC house with a terracotta roof in Studio.](https://mintcdn.com/ideatura/MJ3FvHQFVwvFuYO5/images/v2/house-refined.jpg?fit=max\&auto=format\&n=MJ3FvHQFVwvFuYO5\&q=85\&s=e1d92ddb2b48e0b09f6a24e3ed723827) The same house after a follow-up request to change the roof colour. ## Download the IFC With the result open, click **Download and export** in the viewer's top bar and choose **Download source IFC**. Save the file on your computer. ![Studio's Download and export menu with Download source IFC selected for the house.](https://mintcdn.com/ideatura/MJ3FvHQFVwvFuYO5/images/v2/house-download.jpg?fit=max\&auto=format\&n=MJ3FvHQFVwvFuYO5\&q=85\&s=fd14d25b7803414464e8697ef2d3a1e6) Download source IFC saves the building model. The other options export the visible scene as GLB or glTF. You now have a model you can reopen in Studio or use in another application that reads IFC. > **[Explore Studio](https://docs.ideatura.ai/v2/essentials/studio-overview.md)** > > Find your files, mark up a view and organize your work. > **[Try a Revit task](https://docs.ideatura.ai/v2/quick-starts/revit.md)** > > Connect a Revit plan, add dimensions and save an automation.
