CAD drafting Global Searching for Features 6 Command line: PC_FEATURES

 

The command searches for features in the point cloud using the RANSAC method: planes, spheres, cylinders, cones, tori.

The command options are set in the Properties bar.

Options:

DetectPlanes

DetectSpheres

DetectCylinders

Whether to search for the specified geometry shapes

MaxCylinderRadius

Maximum permissible radius for cylindrical shapes to be recognized.

DetectCones

DetectToruses

Whether to search for the specified geometry shapes.

Group Tolerance

The size of the conditional cell in drawing units. For large clouds, recognition times may be unacceptably long. To speed it up, the number of points considered is reduced by averaging coordinates and attributes in cubic cells of a specified size. The larger the cell size, the fewer points are taken into consideration and the higher the recognition speed will be.

If value = 0, grouping is not performed (disabled).

Epsilon

Epsilon surface of the form. Determines how far points belonging to a surface can be from this surface.

Bitmap Epsilon

The maximum distance between points at which they are considered to belong to the same feature.

NormalThreshold

The threshold value of the form validity criterion when the form is considered found.

Probability

The threshold value for the feature reliability criterion at which a feature is considered found.

MinSupport

The minimum number of points in a feature at which it is considered found.
