Hi there! I see you're having trouble with CamToPlan showing a "detection problem" and no grid appearing. To help you better, could you please share a bit more about when exactly this issue happens? For example:

- Are you trying to scan a particular surface or area?
- Does the app open your camera fine but just not show the grid?
- Have you recently updated the app or your device software?
- Are you using any kind of protective lens or any unusual lighting in the area?

Meanwhile, I can guide you on some common things to check that often resolve detection grid issues:

1. Lighting and Surface: Make sure you're scanning a flat surface with good, even lighting. Sometimes very shiny, reflective, or dark surfaces confuse the detection.

2. Camera Permissions: Verify that CamToPlan has full permission to use your device camera. On Windows with a WebKit browser, check your browser's camera access settings.

3. App Reload or Restart: Close the browser completely and reopen CamToPlan, or clear browser cache related to the site to refresh the session.

4. Camera Focus and Lens Clean: Ensure your physical camera lens is clean and the camera is focusing properly on the surface you want to measure.

5. Try a Different Area: Sometimes trying the app on a different surface or area can help rule out environment-specific issues.

If those don't work and you're still seeing "detection problem" with no grid appearing, let me know which exact step you've tried already, and we can explore deeper settings or alternative solutions to get this sorted for you!

I've already tried all of this. All I see are yellow dots when I try to scan

Thanks for the extra detail about the yellow dots appearing during scanning. That helps a lot!

The yellow dots you’re seeing typically represent detected feature points in the environment that the app uses to understand surfaces and depth. When the app shows only yellow dots without the grid, it usually means it’s detecting points but cannot form a stable 3D surface or plane to generate the measurement grid.

Given you’ve tried the basics already, here are a few advanced tips to help resolve this:

1. Check for LiDAR or Depth Sensor Support: On Windows devices using WebKit browsers, the depth sensor or built-in LiDAR (if any) might not be fully accessible or supported. CamToPlan often relies on depth sensing or AR frameworks that may have limited functionality in this environment. Unfortunately, this can cause detection to be limited to feature points (yellow dots) without a real grid forming.

2. Reposition and Rescan: Slowly move your device closer and then away from the surface while keeping the camera steady. Sometimes this motion helps the app better calculate distances and surfaces.

3. Surface Texture: The surface scanned should have some texture or pattern for the app to detect planes. Completely smooth, glassy, or uniformly colored surfaces often result in lots of yellow dots but no grid.

4. Browser and Device Compatibility: Since you’re using a WebKit-based browser on Windows 10, ensure your browser is updated to the latest version. Also, if possible, try using the dedicated CamToPlan app on a supported device like an iOS or Android smartphone with ARKit or ARCore support, as that often resolves sensor-related issues.

5. Allow Browser Access to Sensors: Some browsers limit access to camera features or sensor data (like accelerometer) needed for AR mapping. Double-check your browser settings to enable full permissions for the app’s site.

If after these steps you still only see yellow dots and no grid, it might be a limitation due to the device and browser environment, as the full AR plane detection needs hardware and software support that’s better on mobile AR platforms.

Would you like guidance on trying the dedicated app on a smartphone? Or should I help you check your browser and sensor permissions in detail on your Windows device? Let me know how you’d like to proceed!

I am using Camtoplan on an iphone

Thanks for letting me know you're using CamToPlan on an iPhone! That helps clarify things quite a bit since iPhones with ARKit support generally provide much better AR surface detection.

To help you get the grid working and the detection issues sorted on your iPhone, here’s a simple step-by-step guide on using the CamToPlan app effectively:

1. Ensure App Permissions: Make sure CamToPlan has full access to your iPhone’s camera. Go to Settings > Privacy > Camera, and confirm CamToPlan is allowed.

2. Good Lighting and Surface: Position yourself in a well-lit area and point your camera at a flat surface with some texture (avoid plain white walls or glass surfaces). The app needs recognizable features to detect planes.

3. Move Slowly to Calibrate: When you start the app, gently move your iPhone camera around the area you want to scan. This helps the AR system map the environment by detecting multiple points.

4. Look for the Grid: Once the app detects a flat surface, it will overlay the measurement grid. Yellow dots indicate feature points, so initially, seeing a few is normal, but after a moment the stable grid should appear.

5. Restart if Needed: If the grid never appears, try closing and reopening the app, or reboot your iPhone. This can often refresh sensor calibration.

6. Keep iOS Updated: Make sure you have the latest iOS version installed since ARKit updates can impact performance.

7. Optional - Watch a Demo: If you'd like visual guidance, this CamToPlan demo on YouTube shows how to measure vertically and horizontally with the app.

If you’ve done all this and still only see yellow dots but no stable grid, it could be worth reinstalling the app or checking if your specific iPhone model supports the needed AR functionalities, especially LiDAR if you have a Pro model.

Does this help you get the grid working? Would you like me to guide you through checking your iPhone’s AR capabilities or troubleshoot specific app settings next?
