# Troubleshooting

<details>

<summary>My floor plan will not upload. What should I check?</summary>

First, confirm the file format is supported: DXF, DWG or PDF for Lite mode, and DXF or DWG for Pro mode. Check that the file is not corrupted by opening it in another application. For DXF/DWG files, ensure the drawing is not excessively large or complex (very large files may take longer to process). For PDFs, confirm the floor plan is drawn to scale with a clear dimension reference. If the issue persists, contact <info@laiout.co> with the file attached and a description of the error.

<summary>In laiout Pro, I clicked Mark as Complete but received an error message. What should I do?</summary>

The error message indicates what is missing before you can complete the floor plan setup. The most common requirements are: adding a region where laiout will generate layout options, marking the external space outside the floor plan boundary, and drawing at least one corridor. Review the error message, address the missing element, and try marking as complete again.

<summary>The generated layout does not match my preferences. What can I do?</summary>

Check that your preferences are correctly set in the Preferences panel before generating. Make sure you have clicked Apply after making changes. If the layout still does not match, try adjusting your corridor position, as this has a significant impact on how the algorithm distributes space. You can also try Enhanced Precision mode in Advanced Preferences, which gives the algorithm more processing time to fulfil complex requirements. If specific room types are missing, check whether your floor area is large enough to accommodate all requested spaces.

<summary>I cannot find my saved favourite. Where is it?</summary>

Favourites are saved per floor. Navigate to the floor where you saved the favourite and click on the 3 dots on top of the floorplan card and select the star icon where you will find the saved floorplans for that floor.

<summary>The 3D view is not loading properly. How do I fix this?</summary>

Ensure you are using a supported, up-to-date browser (Chrome is recommended). 3D rendering requires WebGL support, which is enabled by default in modern browsers. Check that your internet connection is stable and that you are not connected through a VPN that may limit bandwidth. Try clearing your browser cache, disabling browser extensions that might interfere with graphics rendering, or switching to a different browser. To verify WebGL support, you can visit a WebGL test website. If the issue persists, contact the laiout support team for assistance.

<details>

<summary>My exported file looks different from what I see in laiout. Why?</summary>

Some visual differences are expected between the in-app view and exports. CAD/DXF exports contain all spatial data and layers but may not carry the same colour rendering as the app. Revit exports map elements to Revit families, which may display differently depending on your template settings. PDF exports should closely match what you see on screen. If you notice significant discrepancies, ensure your preferences are set correctly before exporting and contact the laiout support team if issues persist.

<details>

<summary>The platform is running slowly. What should I try?</summary>

Platform performance depends on your internet connection, browser, the complexity of the floor plan, and the size of any custom furniture models you have uploaded. Try closing other browser tabs, clearing your cache, or switching to Chrome if you are using a different browser. Very large or complex floor plans (particularly those with many layers in DXF/DWG format) may take longer to process. If you are connected through a VPN, try disconnecting to improve connection speed. If performance issues persist, contact the laiout support team.
