 XYZ Differences. Measure the distance between two points in the model, and view the XYZ differences when measuring. When you tap and hold a point, guides appear to help you make accurate measurements. A magnifying glass icon focuses on the area beneath your finger. Use it to measure with precision and see areas that might otherwise be obscured. You can then snap to a surface, corner, or edge.
