Common Questions

Can I measure distance in a scanned PDF?

Yes. Since we use a visual overlay, you can measure distance on any visual element, even if it's a scanned image.

Is it accurate for blueprints?

For standard scale drawings on A4 paper, it is very accurate. For other scales, we are adding manual calibration soon.
