> ## Documentation Index > Fetch the complete documentation index at: https://beta.docs.ideatura.ai/llms.txt > Use this file to discover all available pages before exploring further. # Viewers and markup > Inspect references beside the conversation, capture views and add markup. Use a viewer to read a drawing beside your chat. Mark the part you mean, then ask a specific question or describe the change you want. For example, circle a roof junction and ask Ideatura to explain its layers. ## 1. Side panels Open a file beside the conversation to read it while you work. Use the file tabs to switch references and the panel boundary to adjust the space. Closing a preview leaves the file in place. ![PDF side panel with file tabs and close-preview control.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-tabs.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=d7d1445b5c36ecf1cc4f72d775996ad5) An image attachment can also open over the conversation. Click it to inspect the image, then close the preview with **X**. ![Image attachment preview over the conversation with the close control labelled.](https://mintcdn.com/ideatura-preview/zrlaBDxcT398OXQa/alpha/images/studio-tour/reference-preview.svg?fit=max\&auto=format\&n=zrlaBDxcT398OXQa\&q=85\&s=c517ebaa0d55fedf872a2a377059907f) ## 2. Capture a view Connect your application, then click **Connected App screen capture** at the upper right of the message box. In the live-view tab, click **Capture** to open an image of the current view in a new tab. This example captures the Revit plan **DOCS - Grid dimensions**. ![Captured DOCS - Grid dimensions Revit plan in Studio, with the Capture control labelled.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/revit-capture.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=23062f38459c9c05b24ce7ee5266ed06) For a drawing or photograph saved as a file, use **Attach file** in the message box and add your request. ![Image attached to a Studio request with an Attach file control and architectural question.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/image-attachment.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=0c4221b749fec4489403ae9df755d5b8) Use **Fit page** to see the whole drawing, or **Fit width** and **Fit height** to fill the viewer in one direction. Zoom in when you need to read a detail. ![PDF fit menu with Fit page, Fit width and Fit height.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-fit.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=f264149d5cdd8e519fc5b1c2be325d44) Choose **Clip** and drag around the detail you want to discuss. The area outside your selection dims, helping you check what the crop includes before attaching it. ![Clip enabled with the WC detail selected and the area outside the crop dimmed.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-clip.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=e5c867d2678361266a4a745587edf48d) ## 3. Add markup Use **Pen**, **Text** or a shape to mark the detail you want to discuss. Choose a contrasting colour and add a short request, such as “Explain the clear space around this WC.” For a change, say what should move or change size and include exact dimensions where needed. ![A rectangle drawn in Studio around the turning-space detail, with shape and colour controls and selected markup with resize handles.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-markup.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=21d978b8d0571ec639bdc16aaa506366) ## 4. Edit markup Use **Eraser**, **Undo markup** and **Redo markup** to correct your marks. **Clear markup** removes them so you can start again. Review the marked detail before sending your request. ![Marked WC detail with Eraser, Undo, Redo and Clear markup controls.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/markup-edit-controls.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=560b911329816cb3a53ac59b45293b9d) ## 5. Viewer actions Use **Attach** to add the visible image or PDF area, or your selected crop, to the next message with its markup. **Pin** keeps the file available throughout the conversation; **Unpin** removes it from that context. **Clone** makes your own copy in Workbench. Check the attachment before sending. ![Expanded PDF viewer actions showing Attach, Pin and Clone.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-actions.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=874b97d4e8329fb814758a909605c2f1) ## 6. Save viewer files Use **Download** in the viewer’s top bar to save the file to your computer. Download is also available for formats Studio cannot preview. For model downloads and temporary section views, follow [IFC viewer](https://beta.docs.ideatura.ai/alpha/overview/ifc.md#save-drawing). ![PDF viewer top bar with Download labelled.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-download.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=f27a0c95a420a5398008509eb1a040b8) ## 7. Read a PDF Use **Previous page**, **Page number** and **Next page** to find the drawing, then fit or zoom the page to read it. Name the page or diagram in your request. Here, Diagram 18 in *Approved Document M, Volume 2: Buildings other than dwellings*, with 2024 amendments, is on printed page 51 but PDF page 53. ![Approved Document M Volume 2 open on PDF page 53, printed page 51, with Fit page, zoom and page number controls.](https://mintcdn.com/ideatura-preview/1ZBJlJYn0qj3l5_m/alpha/images/viewers/pdf-viewer.svg?fit=max\&auto=format\&n=1ZBJlJYn0qj3l5_m\&q=85\&s=ae9c4f5563cd08b25afc2ea1d5ec1f67) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
