Fit Cylinder

Geometry

Type of created object.

Data source

Point clouds: geometry is generated in two ways:

1. The user selects an area containing points, and the program immediately attempts to construct an object and display a preview. The Searcher parameters panel opens, allowing you to refine the selection parameters for greater accuracy:

·              Thickness tolerance — maximum deviation of points from the geometry

·              Maximum gap — search step/distance between points

·              Region size — radius of the search area from the geometric center of the initial selection

2. The user selects one or more points from which the search will begin. A preview of the object will not appear until the points necessary for construction are found or selected.

Points: geometry is constructed exclusively from the selected points. The program does not analyze the entire cloud; the user controls which points are included in the construction (the points may be scattered and unconnected).

Threshold distance (axis)

The maximum deviation of the point cloud’s positions from the ideal. That is, the spread of coordinates that can be ignored in order to consider the points as belonging to a single line, surface, edge, etc. The threshold distance should be greater the less accurate the scan is and the worse the object’s surfaces and edges are expressed. However, if the threshold distance is increased excessively, the probability of inaccurate cylinder axis placement increases.

Threshold distance (point on axis)

The maximum deviation of the point cloud’s positions from the ideal. That is, the spread of coordinates that can be ignored in order to consider the points as belonging to a single line, surface, edge, etc. The threshold distance should be greater the less accurate the scan is and the worse the object’s surfaces and edges are expressed. However, if the threshold distance is increased excessively, the likelihood of inaccurate cylinder placement increases.

Draw solid

Specify whether to create the cylinder solid during this and subsequent command sessions.

Number of closest points

The number of cloud points in the nearest neighborhood to calculate the surface normal.

Number of axis iterations

The number of iterations used to determine the direction of the cylinder axis. A higher value increases calculation time but also improves the likelihood of finding the correct direction.

The parameter value must be greater than 0.

Number of points on the axis iterations

The number of iterations used to determine the point on the axis and the cylinder radius. A higher value increases calculation time but also improves the likelihood of finding the correct direction. The parameter value must be greater than 0.
