Creates point type object snapping to point cloud
Draw new line by snapping to point cloud
Opens automatic feature extraction settings
Extracts a corner line between point cloud planes, by selecting click1 and click2

Automatic feature extraction settings

Step size value should be 3-5x bigger than point cloud density (distance between neighboring points).

A Bigger step means, a bigger distance between point cloud points for plane extraction. By selecting a bigger value, you will be able to extract large planes (for example: walls, columns, roof plane windows frames)

A Smaller step means, a smaller distance between point cloud points for plane extraction. By selecting a small value, you will be able to extract smaller planes (for example: windows frames, door frames)

Resets step size to default
Curvature Tolerance. If the surface is bumpy or curvy by increasing tolerance you will be able to create a detailed mesh and capture small bumps and curves.
Keep Vertical means that the extracted plane will stay in the vertical position.
– Select initial point location to extract plane
– Extracted plane scale function
– Extracted plane rotate function
– Extracted plane press&pull function
– Finds and creates surface mesh according to extracted plane

Example: Plane Recognition settings

Well recognized plane (Step size 0.04 m) Badly recognized plane (Step size 0.24 m)

Example: Surface creation with small step size

(Step size 0.34 m)

(Step size 0.34 m) increased “Curvature tolerance”

Detailed ground mesh created until first bigger bump Detailed ground mesh created in all areas

Example: Surface creation with bigger step size. A Bigger step means a more decimated mesh without small bumps and curves.

(Step size 1.34 m)

(Step size 1.34 m)

Detailed ground mesh created until first bigger bump Detailed ground mesh created in all areas
A ground surface mesh can be created from an unclassfied point cloud
