What you can do with your LAZ file

View the scan in 3D

Turn the point cloud with the mouse or touchpad and zoom in on any part. Front, Top and Isometric views are one click away.

Measure distances

Measure Distance shows the distance between two points you pick in the cloud.

Cut a section

Section cuts the cloud with a plane to show one slice of the scan.

Check the extent

Bounding Box draws the overall size of the scan. The Information panel shows its dimensions and the number of points.

Convert the points

Export the cloud to PLY or ASC on the converter pages or in the free desktop app, where Scans to Mesh also builds a mesh from it.
